Near the city of Globe Arizona, the Salt River flows. In the canyons around this important waterway, there are several outcrops of serpentine with various stringers of fibrous Chrysotile, the safest variety of the fiber form minerals processed into asbestos materials. Alternating veins of calcite\/aragonite, serpentine and chrysotile created a valuable ore to be mined for a period of time. The mines were so profitable that various buildings were erected to serve the miners of the salt river valley. <\/p>\n
