city, Hutchinson county, northwestern Texas, U.S., in the Texas Panhandle, near Sanford Dam, 45 miles (72 km) northeast of Amarillo. Part of the Borger-Phillips-Bunavista tri-city industrial complex in an area producing oil and gas, Borger was founded in 1926 and incorporated the same year with the completion of the first oil well. Overnight it became a boomtown of tents and shacks; it was named for A.P. Borger, a land investor. Major industrial products include (in addition to petroleum and natural gas) carbon black, printer's ink, and synthetic rubber. With increased irrigation, diversified farming and cattle ranching have become economic assets. The city is home to the Hutchinson County Museum and Frank Phillips (community) College (1946). Nearby, on the northern edge of the Llano Estacado, is the Lake Meredith National Recreation Area. It includes Lake Meredith, impounded by Sanford Dam, and Alibates Flint Quarries National Monument. The monument, established in 1965 and occupying about 2.1 square miles (5.4 square km) commemorates and preserves the ruins of 12,000-year-old Indian quarries, which are accessible only by prearranged guided tours. Inc. 1926. Pop. (1990) 15,675; (2000) 14,382.
