Cowboys drove cattle herds to market at the railroad centers in the: Midwest. The hard top layers of buttes, called caprock, resist weathering and erosion. Sets at the southwestern margin of the Mountains Rise more than 6,000 above. This distinctive profile is a legacy of the range's remarkable geologic history and the structure of its bedrock. Mt. The hump of Camelback Mountain is made mainly of granite, which forms via volcanic activity underground. Secondary copper enrichment and oxidation have yielded minerals with even higher copper concentrations, including chalcopyrite, chalcocite, azurite, malachite and chrysocolla. Today, we know these blocks as Camelback Mountain and the Tempe Buttes. The Santa Catalina Mountains north and northeast of Tucson contain the Wilderness Granite, which formed as an intrusion 14 miles below the surface.
