Ebooks for Rockhounds – Information at Your Fingertips

Our portable electronic devices have memory that allows them to store thousands of pages of information in the palm of your hand. To a mineral collector a century ago, it would sound like total magic. By storing a library of field collecting sites in the palm of your hand on the Kindle or other device, you’ll never run out of places to go. Perhaps to your surprise, many great guides are available in digital format so you don’t have to bring stacks of field guides or a cumbersome library of dated, out of print texts with you when you get muddy. The rockhound ebook revolution is happening now. Let’s take a look.

Check out all the ebook field guides listed for sale on Amazon!

As you can see, there are some great choices for guides on Amazon. Just by searching “rockhounding” in the Kindle ebooks section of Amazon, I got 55 results, most of them being informative guides to collecting sites and prospecting methods. Imagine how much information you can have at your fingertips! Mineral collecting books tend to be really affordable, I had a hard time finding one that cost $20 or more. Although the feel of a paper text is nice, you can’t beat the price and field-usefulness of these ebooks.

Searching “mineral collecting” brings up less field guides, but still a lot of them. Notice a trend? Seems like digital versions of field guides are getting popular! Take advantage of this.

Searching “mineral collecting” brings up one of the best recent field guide for collecting minerals in Southern California — Rockhound Barstow: Mineral Collecting in the Mojave Desert by Justin and Brandy Zzyzx. This great guide to collecting a wide variety of material gives you tons of sites that are currently open to the general public where you can find mineral specimens and lapidary material! If you had read some field guides, they will provide directions and info on sites, but note that they are closed to collecting. This great guide gives you places in SoCal you can actually visit and dig.

Another thing to mention, are PDF files of old texts and surveys available for free online. Museums, universities, personal websites of collectors, and state and national government geological surveys are some places where you may find many old texts that have been digitized for your convenience. Looking at these types of resources is a good way to find old localities. These types of texts often include sites that the newer guides do not, and while they require a bit more fishing around in terms of actually finding them and acquiring permission, the rediscovery of an old site might produce some amazing results.

Here is an example: https://www.des.nh.gov/organization/commissioner/gsu/documents/nh-mines1960.pdf

Screenshot of the PDF of this classic guide.

This classic guide by Philip Morrill, published in 1960 is notoriously difficult to find in print but known among NH collectors for the unique, often forgotten localities described within it. This book is something you probably wouldn’t want to bring into the field with you because it would be hard to get another copy. Now you can have the info in your digital library and bring it with you without trashing your copy

Ebooks and PDFs are a powerful tool for the collector looking to get themselves into new areas or sites. The advantages modern collectors have over previous generations due to the amount of technology and convenience available have allowed for a lot of new discoveries and rediscoveries of old localities. If you haven’t been using these resources and are itching to find a new place to hunt, then it’s time to step on board the digital library revolution!

Product Review: Cut That Agate- Speedy Tumble Rapid Refil Kit – Tumble Stone Polish Kit

Paid Review By Jeremy Zolan
Insta: @leaverite_tycoon

Speedy Tumble is a product released by Cut That Agate that provides the rough material and everything you need to tumble a wide variety of stones to a high, professional looking finish in under 1 month time. The only thing not provided are the tumbler itself, water, and optional Ivory soap. In essence, it is the fast food of tumbling- an inexpensive, highly consistent product that can be made in a comparatively short time. Unlike fast food, the quality of the product is great and I am very satisfied with the fact that there were probably over 50 different kinds of rough in my assortment. You get 4 pounds total. Speedy Tumble also includes a bag of one pound of premier material too. I think my bag had some almandine garnet. I think it’s amazing what they give you for only $30!!

Notice the awesome container they give you as well as the colorful, high quality printed materials and instructions. This is a great looking set!!

To test Speedy Tumble, I decided to take the minimal amount of time it instructed to tumble for. So from start to finish, three weeks and one day total time. For my tumbler, I decided to use the most convenient option I could find. That meant I decided to take a trip down to my local Harbor Freight and purchase their Chicago Electric 3lb. rotary rock tumbler. It proved to be surprisingly well made, rigid, and perfect for getting the results I desired. Definitely a surprise.

I decided to leave some headspace in the tumbler barrel, and filled it about two thirds of the way with stones from the set that I lightly prewashed. It’s a bad idea to totally fill the barrel, so the stones can move freely and let the grit work them.

I added about 3.5 tablespoons of 400 grit, added some water, sealed the drum, released pressure after 3 hours, then tumbled for one week uninterrupted.

One week later I opened the barrel, placed the rough in a strainer and carefully rinsed off the grit. The material is looking nicer!

Strained and Cleaned of grit, the material is already looking much nicer!


Back into the tumbler with the 800 grit for a week. I repeated the same procedure as that for the 400 in terms of amounts.

Getting more tumbled! I washed this material well and then added about half the envelope of cerium oxide powder and more water.

After a week with cerium oxide, I washed the material well and added a small chunk of Ivory soap and tumbled with a little water to get a higher gloss. There you have it! It’s finished! Let’s take a look:

Here is a handful of the beautifully glossy finished product. Ready to go for a craft project or just to enjoy!

Summary: Overall I really like Speedy Tumble and I think the value is amazing. Not only do they do the dirty work for you, but they include the grits you need to finish the job. You get a ton of material and the quality is great. I found many semiprecious stones in my assortment including amethyst, rutilated quartz, agate, sodalite, and turquoise. The only thing I can really criticize is I wish the premier material was something a little more colorful, but I can’t even really complain because of how well executed everything else was. Great job on making an interesting product for all ages, Speedy Tumble

Rocks and Minerals Very First Issue! – Free PDF of this Mineral Magazine

Many years ago we came across a fun find – one of Peter Zodac’s leftover copies of Rocks and Minerals first issue published in 1926.

This magazine is now and has been for decades, a bold, colorful magazine, since 1979 under the direction of Marie Hunzing.

Back in the 1960’s it was a digest sized black and white magazine with short articles and monthly articles devoted to sand and fossils.

Here is the very first issue, purchased from Alfredo Petrov, who got it from Tony Nickischer, who got it from Peter Zodac’s house.

Rocks_and_Minerals-1926-September

It is a curious document, showing that the first issue was heavy on personal advertising, more of a catalog than a magazine.

Every mineral collector and rockhound should have these books by John Sinkankas

Cover of the Book Mineralogy

Rockhounding is a great hobby, rewarding and full of adventure. Few people know that to progress in knowledge about this hobby is easy as can be, it just take a little bit of reading and we have the perfect selection of books to talk about today, ones that will give you a full understanding of minerals.

All of these books were written by Captain John Sinkankas, a well noted and respected author who has a way of explaining things that many thousands of people have enjoyed and understood.

The most important thing about this article is the perception of mineral information, versus the reality. Guidebooks like the National Audubon Society Field Guide to North American Rocks or the handy Smithsonian Handbook, well, they just do not do a good enough job, in our opinion. Sure, they are colorful and glossy, most starting collectors will have one or the other at some point in their life. However, if you have more than just a passing curiosity about rocks and minerals, there is a better way.

Cover of the Book Mineralogy

John Sinkanas’ book “Mineralogy” is our #1 pick for must have mineral books



Mineralogy
is the #1 book that we recommend to all mineral enthusiasts. The writer, John Sinkankas, has an easy way of explaining how atoms form crystals, and why the crystals different properties make them look different from each other. It is technical mineralogy explained in a way that most anyone can understand. The book can be treated as a college level book on the subject, yet, can be enjoyed casually with chapters devoted to different topics including over 300 photographs and line drawings, this is the must have book for everyone interested in the subject. You can find this book on Amazon and eBay. It was originally published in the 1960’s, any edition is worth owning. You will find it as a “Used” book, it typically retains value as it is a book that all mineral and rock collectors have loved for decades.
Cover of the book, Gem Cutting: A Lapidary's Manual, by John Sinkankas

Gem Cutting: A Lapidary’s Manual, by John Sinkankas



Gem Cutting: A Lapidary’s Manual
is John Sinkankas’ perfect tome devoted to all the basics of lapidary. The mystery of most every lapidary art is reveled, along with photographs and drawings to guide you to understanding the complete basics of lapidary arts. In the first chapters you are introduced to sawing, grinding, lapping, sanding, and polishing. Rock drilling is a common question, this book gives you the knowledge on that, plus, all the tumbling, cabbing, faceting, sphere-making, carving and engraving and mosaic and in-lay work information, including tools of the trade, tips on techniques and so much more. When I need to know what polish to use when I’m tumbling stones, I look to this book. This has an amazing wealth of information on this subject. The second edition is the edition we suggest and the big paperback edition is a great addition to any library.

Book cover of Prospecting for Gemstones and Minerals

Prospecting for Gemstones and Minerals is the best book to teach you about mineral collecting


Prospecting for Gemstones and Minerals is a perfect primer to understanding where to find rocks. Deposits are explained, how to find them, what is inside of them, and how you can get crystals out of the ground. This book serves as a primer to all topics on the subject of rockhounding. Over 350 pages of quality information, that, if you were to read, would put you in the ranks of the top collectors.

All three of these books are easy to read and understand, teach you the basics and the nuances of each subject are highlighted and explained. To read and understand these three books is to have a near complete general knowledge on this subject of rock and mineral collecting.

Petrified Wood Near Colorado Springs – Pairing Old Information with New technology!

Cover of Gems and Minerals, August 1967 with a stone horse on the cover.

Rockhounding is a hobby that anyone can pick up, with very little in the way of costs besides time and transportation. Colorado is a wonderland of mountains, forests and rocks. Petrified wood is always fun to find and in many places around Colorado, abundant. Let’s show you a fun way to research locations from old data sources.

Cover of Gems and Minerals, August 1967 with a stone horse on the cover.

Available on eBay, Amazon, and at mineral shows across the nation, old magazines are full of rockhounding information!


By old data sources, we mean, old magazines, books and pamphlets about collecting minerals. Rockhounding was very popular in the 1950’s, 60’s and 70’s, which lead to the production of all sorts of printed material for rockhounds and lapidary enthusiasts. Today, even if rockhounding was nearly as popular as before, the internet is the land of independent media, yet, the information from those sources is so niche, it takes people specialized in transferring that information over to bring it to light, instead of waiting around for others to research and publish, you can take charge and research many things from your computer, using information from sources like this one, The August 1967 edition of “Gems and Minerals”.
article in 1967 Gems and Minerals about collecting Petrified wood in Colorado

Click to see at full size


The article, entitled “Petrified Wood in Eastern Colorado” by Eugene M. Beason, describes a large wash where petrified wood is plentiful. Due to the nature of these alluvial rock deposits, every year new material is churned up by erosion by wind and rain, so if there was ample material in 1967, there would be ample material in 2016. Property ownership is always evolving and changing and must be verified by any possible explorer.

Map from 1967 Petrified Wood in Colorado Article in Gems and Minerals

Original Map to the Petrified Wood Collecting area in the 1967 Gems and Minerals article.

Many things have changed since this article was printed, nearly 50 years later. Instead of the turn being the “Skelly Station”, we can see the map is pointing to “Peyton Highway”, which runs north to go over a mountain pass and turns hard left (west) on “County Road 74/82”, which parallels the wash that is talked about in the article. I do not think there is any need to stop at the farmhouse listed in the article to ask for permission, as the ranch land gave way many years ago to the need for housing, as the populations in nearby Denver and Colorado Springs swelled, so did the growth out into the nearby countryside. 50 years ago there were just cows and a couple windmills, now there are hundreds of houses dotting the landscape. The issue is that the property in Colorado has two things going against it – Waterways can be included in property lines and property does not have to be POSTED to give first refusal to entry, as in most states in America.

map showing petrified wood collecting area north of Peyton Colorado

This map shows the area as shown in the illustrated map above.

As we searched google for information on this location, the terms “Peyton Petrified Wood” were coming up nearly blank. We did find an entry for it on Mindat.org, but it did not show anything directly from this location. Additionally, PeaktoPeak, a well known website for Colorado collecting, has a bit about petrified wood from that general area. Digging through field guides to Colorado, we could not find this location listed, could it have been one of the locations that simply slipped through an information hole, getting a two page article and then just…relegated to maybe popping up in a mention in a local club newsletter. It IS possible to contact the property owner, Tim Richardson, at timothy.k.richardson@gmail.com for guided tours of the petrified wood deposits.

map showing the distance between denver and colorado springs and petyon colorado

as you can see, Peyton is not a far drive from Denver or Colorado Springs

Researching where rocks are found is necessary and interesting – don’t neglect to inspect old magazines and field guides from 40, 50, 60 years ago. You never know when a good location has simply fallen through the cracks and is waiting for you to find it and come explore! You’ll find that property ownership has changed over the years, however, don’t neglect to contact current property owners about that old information – many people are excited to find colorful rocks and minerals and are surprised they are underfoot.

So, when ever the rain is hard in colorado, new material is unearthed!

Jewelry Making – Tips and Techniques covered in two new books

Over the past two months, I have given several lectures on both coasts of the United States, and during that time, had a chance to investigate two books by the authors.

Brad Smith, one of my early mentors in the Culver City Gem and Mineral Club, published a book called “Bench Tips for Jewelry Making”. One of the things about Brad is for a time he could not make it to many of the meetings as he was busy teaching jewelry making at LAUSD in Santa Monica. I did not know what to expect out of this book, so it was surprising to find out that it is, basically, my favorite kind of book for technical information. Full of short tips covering a wide variety of jewelry making, so much I was inquisitive about, so much that is not just for jewelry makers! Using Alum to remove a broken drill bit might be helpful to jewelry makers, but putting that idea in my head about removing broken bits of metal from non-metallic items, using Alum, was something I did not take home from science class 20 years ago. I’m going to keep it next to my copy of Gem and Mineral Data Book by John Sinkankas, both books, full of great tips!

Bench Tips for Jewelry Making - Available on Amazon.com

Los Wax Casting – Available on Amazon.com

While serving as the guest speaker for the Eastern Federation of Mineralogical Societies twice yearly Wild Acres Retreat I had the opportunity to visit with the classes and instructors. During this beautiful mountain retreat, classes in different lapidary and metal working are offered. I took a class on Geology, while others learned soapstone carving, wire wrapping, gem faceting and my roommate was very excited to take a class on Lost Wax Casting. He planned on making a setting for a beautiful gem yellow idaho opal. When I went to check on him, four days later, he confessed, this was not something you could just JUMP into and showed off his much simpler designs, sans opal. That class visit was fun, the instructor, Fred R. Sias Jr. took the time to run me through all the basic steps of casting in a couple minutes. Looking at the projects the class was working on, I can see this is not something you can do repeatedly, well, without some practice and experience. Fred has a book, which I can highly recommend, that speaks about the methods of wax casting, providing an amazing overview for someone who has never been introduced to this ancient art. For those who are already wax casting this might not provide a lot of new content, Ashanti casting might be something you have not been taught, and Fred Sias does a great job of illustrating this primitive technique.

Rockhounding 101 – How to REALLY FIND minerals and rocks!

[sg_popup id=1]Rocky Rockhammer MascotOn this website we are sharing information about locations that some of the various contributors to this site have gone to. All of us find out about these mineral locations from various sources. Many locations have been talked about in every media format available, some published locations are so well known it is common to run into another collector at any time, some of the locations published are visited less than a couple times a year, if at all. By media, I mean, printed in magazines, books, club newsletters, posted online in forums, websites, on homemade video, on professional video and on television. Some collectors will grumble that all this publicity will make the location run dry. It makes local officials either look forward to increased tourism, or look for ways to restrict access, as if rockhounding was a hobby that allows one to retire early (on public gains!), rather than typically be retired to enjoy! Mineral collecting is a truly patriotic hobby! Knowing and understanding minerals and the deposits has always been a matter of national security, public knowledge and scientific outreach.

While many websites will tell you about what tools you need and speak of rock hammers, backpacks and boots, our #1 tool is knowledge. First hand, published and in modern mythic tales, obtaining information about locations is something that is the first step to find out as much as possible about a location before ever visiting it.

Field Guides are a great resource, as well as magazines focused on rockhounding, from now all the way back into the beginning of the 20th century! Old magazines like “Rockhounds” and “The Mineralogist” are great resources, as well as old and current issues of “Rocks and Minerals” and “Rock and Gem”. All of these can be found for sale on eBay and at various mineral shows around the united states. You never know when you are going to come across a great article about a location you had JUST heard about! One of the most amazing online databases is the complete run of “American Mineralogist” on http://www.minsocam.org/msa/ammin/toc/
The older issues have articles that have lead me to locations that might have been completely forgotten about.

Mindat.org is an amazing database that many of you are already familiar with, however, we often forget to think about just how amazing this database is, including lists of references for corresponding articles and books about the subject.

Geology Departments of the state you live in or adjacent to you, has produced several state reports on mines and minerals, which will often include information that can be very useful now. In the early 1900’s, feldspar was an important commodity, unlike now. Knowledge of mineral deposits will tell us commercial feldspar deposits also had garnets and schorl tourmaline, sometimes quartz or even topaz. Often an entire hardcover book has been produced, detailing the minerals and the locations they are found, across the state. California has at least THREE editions of this kind of text and I’m sure there are several people planning the next edition.

Road Atlas are great to have when you are planning and while you are en route. I personally love the DeLorme series, nice large print maps that have helped guide me to countless locations. The BLM has a program you can use, the LR2000, but my personal favorite database is the MRDS, Mineral Resource Data System, detailing the principal and secondary ore and location of all working, placed and closed mines and mineral locations. Just load the map and locate your location. I think you’ll be surprised what you might not know about the mines in your proximity. While traveling through Utah and Colorado, our Road Map was invaluable, showing BLM land that was open for public camping.

Clubs are a real mixed bag, but as such, you will inevitably come across information from all directions. Both of my favorite beach and fossil collecting spots were told to me by a lady at the Searcher’s Rock Club in Anaheim California. Right now in 2013, I’m cleaning minerals and going field collecting with a friend I made from attending the Culver City Club back in 2004. That is a collecting friend who has gone on dozens of collecting trips with me over 9 years. I’ve learned about so many parts of this hobby from mineral clubs and it has been an enlightening experience in many ways. You can get a complete list of mineral clubs here.

We loved this idea so much, we made it. The Mineral Search Page located Right Here on WheretoFindRocks.com, is something that we made from our LOVE of the general searches for states, countries and forms on eBay. The idea behind this is that if you check out the eBay results for your state, or general area, you’ll come across people who have gone out collecting at public locations and put something on eBay. This can easily lead you to general areas to collect minerals. It is a great first step in researching current producing locations.

Museums and local collections are great resources. You’ll find the museums thing to be easy, if not a long term task. Searching out collections, both old and current, are wonderful sources of information. For instance, if you wanted a good run down of California locations, the Natural History Museum of Los Angeles has an entire wall devoted to very beautiful representations of our state, as well as the California Mining Museum in Mariposa. I LOVED the Wagner Free Institute which had this amazing OLD collection, untouched for a century. In the same vein, the Natural History museum of Prague featured minerals that had not been updated in decades, revealing a great deal of history that is so often removed from the more mainstream commercial museums. Local collections require a bit more finesse and luck. For example, getting to visit private collections can be mind expanding, as many long time private collectors have seen things that were so common for a small amount of time and now virtually unheard of. However, without some sort of recommendation from someone of some sort of personal relation ship with a private collector, most of them are not exactly looking for random visitors. However, if you had been a member of the Mineralogical Society of Southern California, you would have had the chance to visit with several outstanding collections belonging to members of that club. Which takes us back to Mineral Clubs, and why it is a wise idea to be involved with at least one of them.

Going to mineral shows is a great source of information, as the display cases often reveal locations that are open to collection. In fact, the name tags in the cases often match up to the club member’s name tags, the people running the mineral show, and often you can strike up a conversation about their display case.

Libraries all around have lead me to some wild collecting adventures. Your local library is going to have a couple things for sure, often books about the geology of the area, as well as a collection of the state’s publications on geological topics. A great for instance is back in the very beginning of my collecting days, some friends of mine discovered the 1962 edition of “Mineral Collecting in Pennsylvania”, which drove us in a search for the “Azurite” included quartz crystals of Kunkletown. The book was wrong, but there is nothing wrong with Anatase included Quartz, which we found. My most recent discovery of Lawsonite on the beaches of Southern California due to a geological sand sample report. You can read all about that in my upcoming blog entry.

Google Maps and Google Earth are to powerful tools that everyone has at their fingertips. You can do amazing amounts of research with both of these tools, locating mineral locations right down to their visible mine tailings! Understanding the various uplifts, errosion patterns, depressions and faint roads to nowhere are very useful for today’s mineral collector. A simple test, pick your favorite collecting area and look at it on google earth. You will see things you might have never noticed on foot.

Now, my secrets are revealed to you. I hope you use them wisely!

I want to leave you with this note, written by Rock Currier in the publication, “About Mineral Collecting” released by the Mineralogical Record.

Field collectors are a remarkable and accomplished breed. They are perhaps the rarest and purest kind of mineral collectors. They hearken back to the very beginnings of what we now call the earth sciences, and in many ways they embody the simple thrill and youthful joy of the treasure hunt. If you look you will find them “out there” trekking over just one more mountain, digging down just another foot, and hoping for just a little bit longer that they will find something. But remember, the first law of field collecting states: “The best to be found is still in the ground and the best that has been found has be ground!” (that is, ground up into powder in the mill and processed into metal)

2012 Christmas Gifts: Ideas for the Rockhounds in your life!

Gift giving season is officially upon us and for the RockHounds in your life, we made this list of our top 10 suggestions for gifts this year! From stocking stuffers to the item that will make a certain someone squeal with joy, everyone in the office had our eyes set on a few of these items.

#10. Mindat.org Sticker Book – A few years ago Mindat.org published this cute stickerbook and the sticker sets were somewhat difficult to put together. The 10 sticker set is fun, one sticker for each number on mohs hardness scale. For $8.00, these are fun stocking stuffers for kids and adults!

Mindat.org Sticker Book

#9 Colored Mineral Tack – We love this idea, tinted mineral tack. One of the best ways to stabilize a specimen for display, the goal of using mineral tack is to hide it from view. The stark white color makes this task difficult, but these tinted tacks can be a close match for the matrix or crystal color, allowing you to not worry as much about the white tack being the thing distracting from your crystals. In little lumps of colored tack at $1.49 each, you could visit this eBay store and select a few colors and make a set. Every mineral collector NEEDS mineral tack, you can’t go wrong with giving a rockhound mineral tack!

Colored Mineral Tack

#8 The Mineral Art of Hildegard Konighofer – Hildegard Konighofer’s art is shockingly realistic, capturing the spirit of each crystal she paints. This book features dozens of her paintings, which feature a wide array of selections and locations. A beautiful way to cross the worlds of art and minerals together, these limited edition books are sure to be a long treasured item for any mineral collector. Available from Blue Cap Productions for $170.00

DVD set Find your own Diamonds in Arkansas
#4 Magazine Collection/Vug Book – For the book collector that has it all, we can certifiably say that they do not have a full set of The-Vug.com Quarterly Magazine. These sets were HARD to put together, as some of them were only available in Europe, some of them had very small print runs and they were all distributed around the world at different mineral shows. The publisher has made a few complete sets available, but it might be a wise option to buy the full reprint book instead. The magazine (and book) have tons of beautiful photos, articles, maps and information. Any rockhound would love to get this book as a gift! The Original Magazine set is $229.99, the book reprint of the entire series is $34.95

Mineral Website Magazine Book Reprint
#3 All in One polisher – The classic, workhorse all in one flat lap. The perfect item for so many various uses for the rockhound, from grinding matrix, making things display better, polishing cabochons, making freeforms, putting a window on an agate, polishing a face on a quartz crystal, the all in one flat lap is a great gift item for the rockhound in your life! A model like this one, with a series of different grit wheels, runs around $549.99 new. They hold their resale value for many years.

Ameritool All in One Universal Grinder
#2 Blue Cap DVD Sets – Blue Cap Productions produces these fantastic, high quality, in-depth videos of minerals, mineral shows and subjects related to the hobby. I have been witness to what happens when these DVDs are played in a room of mineral collectors…silence. Everyone is so fixed on the screen, looking at the beautiful crystals being presented. These DVDS are awesome, you can put them on anytime, you learn by experiencing all these minerals shown by the people who know them best! Blue Cap productions has these sets of DVDs, one that has all of the What’s Hot in Tucson DVD’s and the other has EVERY DVD produced by Blue Cap, with some great topics! We highly recommend these. $145.00 for the What’s Hot in Tucson Set and $315.00 for the whole production line, the most complete documentary of mineral collecting in the last decade.

Near the border of Archuleta County in Colorado, Wolf Creek Pass and Treasure Mountain contain a deposit of silicates and zeolites that have made their way into mineral collections around the world. The collecting area, spread out over the rocky mountainside, is often referred to as Wolf Creek Pass. However, Wolf Creek Pass is actually a 10,000 foot mountain pass that wraps around Treasure Mountain and follows the Wolf Creek. The mountain does not bear gold or jewels, but the volcanic basalt deposits are near a very photogenic waterfall, Treasure Falls. Surrounded by scenic views, this basalt deposit is one of the most thrilling areas of Colorado. Hotels.com has great deals on hotels around Wolf Creek Pass, Colorado

Treasure Mountain is named after the legendary stash of gold, left behind by a French expedition in 1790. Several search parties have tried to find the fortune of gold bars acquired from a gold deposit near the Peak of Treasure Mountain, but none have been successful in finding the bars or the deposit.

Much of the collecting area is adjacent to highway route 160 and in the boulders and exposed rock of the mountainside just north of the falls. The mineralized area is fairly large and boulders containing the material have been distributed across the area, both naturally and due to the construction of route 160 and Wolf Creek Pass. In fact, due to the close proximity to Archeuleta county to the south, part of the deposit crosses this manmade border separating the counties which only serves to cause confusion in geographic labeling of specimens from this deposit.

Rounded amygdaloids fill the voids in the volcanic deposit of basalt, as with many occurences. These host crystals of quartz and about half a dozen zeolite minerals.

The quartz and agate are similar to that found in many other volcanic silica deposits. The agate is typically clear, white and/or shades of blue, often with alternating layers that make it desirable for lapidary use. Some have crystallized centers. Typically the crystals form on a layer of agate, which varies in thickness from miniscule shells to thick rinds. Sometimes the crystals are amethyst, making attractive specimens on dark colored volcanic matrix. Though the agate and quartz found here do not rival that found at many other locations, it is one of only a few still open for collecting.

Of course, the zeolite species are what makes the location a true Colorado classic. Analcime is typically found as very small crystals usually below 1 cm in size. However, at one location, analcime is found up to 3.5 cm. Chabazite occurs here, but not in crystals larger than a few millimeters in size. Heulandite is sometimes found as crystals up to 5 cm across. However, typically the crystals are only millimeters in size, lining the cavities and serving as matrix to other minerals. One such mineral is mordenite, which is found as well formed clusters of white fibers. These clusters, up to a few centimeters in size, were referred to as being one of the best locations for the species in the United States for many years.

Other associated minerals include globular common opal, small rhombs of calcite, and small pyrite crystals. The locality is also a classic locality for the clay minerals celadonite and nontronite, which form in abundance. Laumonite, natrolite and wellsite also occur in the deposit, but they occur rarely and only as small crystals

Due to the vast deposit and mountain conditions, this source of colorful quartz, agate and zeolites will always exist in the mountains of Colorado. Maybe the lack of gold is a bit disappointing for a mountain with such high aspirations, but to many mineral collectors around the world, the real treaures are the mineral collecting opportunities and the often-visited Treasure Falls.

Field Guide Review: Minerals, Fossils and Fluorescents of Arizona

Minerals, Fossils and Fluorescents of Arizona is a thick field guide to 90 locations across the state of Arizona, most still available for collecting in 2012!

Originally published in 2006, this book contains complete, easy to follow maps and directions to each location, along with colorful photos by Jeff Scovil.
For the absolute beginner, there is a nice chunk of informative reading in the front of the book, giving the basic information for several minerals, along with global mineral information like cleavage, hardness and luster. A bit of time is spent on rock formations and geologic conditions, which will help understand the basics behind why minerals are found where they are.

The copy we have has been used to travel to nearly half of the locations in the book. The book gives clear instructions for reaching a location, along with GPS directions, which are easy to punch into google maps while en-route to a location. In addition, each location pinpointed in the book has produced the material described and only once has there been claim markers up on a location showcased. We have collected Hematite crystals, UV minerals, Dendrites, Calcite, Selenite, and Serpentine. Several trips inspired by this book have resulted in fine specimens that are in our permanent collections.

There are a lot of field guides to choose from, each with their own unique features. In addition to the easy to follow directions, colorful photos and the accuracy of the information presented, the book also does a great job covering the state, listing collecting spots all over the state, with close proximity to other states. For instance, the residents and visitors to Saint George Utah might be surprised to find that a deposit of Gypsum/Selenite is available in the hills stretching out into Arizona, available from the back roads connecting through Utah. More locations spill across into New Mexico and several of them are a perfect distance between Los Angeles and Phoenix.

Many field collecting guides are simply shelf filler, this book has a wide variety of information, collecting options and we can not recommend another mineral field collecting guide more.

Maryland’s Chromite Deposits – A Mineralogical Monopoly

[sg_popup id=1]The Serpentine Barrens of Central Maryland produced an interesting landscape for a 19th century business monopoly on chromite ore, being the sole resource for world looking for new metal alloys. In addition to the facinating story of this legacy of chromite ore, the mines also produced a line of fine minerals, brucite, antigorite in fine crystals and the gem variety of serpentine known as “wiliamsite”.

Today, much of the serpentine deposits in Maryland and Pennsylvania serve as a wildlife sanctuary. The serpentine rocks and their serpentine soils were not fit for cultivation, providing a natural host for sparse grasses, scrub brushy oaks and acid loving pine trees. In addition, rare wildflowers are found only in these uncommon serpentine soils. Because these areas were never fit for cultivating, only nice flat farm land has been turned into housing developments, leaving these woodlands free from destruction. At one point in time, these areas of scrub oaks and rocky soil would have looked barren in comparison to the rich tree heavy forests surrounding that land. Now, in contrast to the houses and civilization popping up in every direction, the serpentine barrens are a rich forest
