Tom Green County comprises 1,540.5 square miles in west central Texas. The county seat, San Angelo, is centrally located at 31°28' north latitude and 100°26' west longitude, 301 miles south of Amarillo and 258 miles west of Dallas. The county has a 235-day growing season, an average temperature range of 32° F in January and 97° F in July, an average annual precipitation of 18.2 inches, and an elevation variation of 1,717 feet to 2,480 feet. The principal river in the county is the Concho, which is formed by the convergence of the North, Middle, and South Concho rivers. The North Concho River and its tributaries, Bald Eagle, Chalk, Dry, Grape, Little, Mulberry, and Walnut creeks, drain the northwest portion of the county. The Middle Concho and its tributaries, Brushy, Dove, Dry Rocky, East Rocky, West Rocky, and Spring creeks, drain the west central and southwest portions of the county. The South Concho and its tributaries, Burks and Pecan creeks, drain the southern part of the county. And finally the Concho and its tributaries, Catelan, Erica, Hog Marsh, Kickapoo, Lipan, and Snake creeks, drain the southeastern part of the county. There are three major impoundments, O. C. Fisher lake, Twin Buttes Reservoir, and Lake Nasworthy. The major soil types in the county are silty clay loams and stony clays. The county has two distinct physiographic regions: the Osage Plains and the Edwards Plateau. In the central, eastern, and southeast sections, the plants are typical of the Lower Osage Plains and the High Plains, including buffalo, grama, wheat, and Indian grasses, with scattered mesquite and zerophytes. The northern, western, and extreme southwest parts of the county have the short grasses and scattered timbers typical of the Edwards Plateau and Hill Country, which include live, shinnery, and red oaks mixed with buffalo and mesquite grasses. There is also algerita, cat's claw, chapparal, prickly pear, yucca, and cacti. Mesquite trees thrive throughout the county, and pecan trees are present in great numbers in the river bottoms. In general, agriculture is dominant in the Osage Plains and ranching in the Edwards Plateau region. San Angelo is the largest processing and shipping center for the wool and mohair industry in the United States. In 1990, 200,000 of the county's one million acres were farmed, including 15,000 irrigated acres. Commercial minerals include caliche, limestone, and oil and gas in the south central and northwest regions of the county. Major archeological sites are scarce in the county. Some scattered artifacts and graves have been discovered, including fifty smooth rock basins near the head of Dove Creek. The most famous aboriginal site in the region is that of Painted Rocks in Concho County, west of Tom Green.
