Early start...

Many of our mines were first opened for extraction in the 1930s. During WWII, the Canon City area played a major role in steel production due to the large deposits of mica and feldspar found here. Following the war in the 1940s our mining efforts turned to decorative, hard aggregate.

The Rocky Mountains and Colorado's Front Range contain some of the greatest concentrations and varieties of hard aggregate found in North America.  Our local area is well known for its fine quality deposits of quartz, feldspar and granite.
