From earliest times, prehistoric people benefited from Moore County’s geological resources by developing the first industry in Texas through mining flint deposits along the Canadian River. Items made from these quarries have been found over a large portion of the western United States. Slabs of dolomite from the area were used to build sturdy, warm homes, and interiors were coated with a mixture of sand, clay, and caliche, an advance uncommon in prehistoric North America. In modern times, people established 31 industries based on oil and gas to take advantage of geological riches untapped by ancient people.
