ROCK CREEK (JACK COUNTY)
ROCK CREEK (Jack County). Rock Creek rises in southeastern Jack County near the Parker county line (at 33°01' N, 97°59' W) and runs south for twenty-four miles to its mouth on the Brazos River, four miles southwest of Millsap in western Parker County (at 32°42' N, 98°02' W). It crosses gently undulating to steep terrain surfaced with shallow to deep sand and clay that support grass and timber. For most of the county's history the area of mixed timber and open prairie has been used as rangeland and for local mineral production. In 1918 a dam was built on Rock Creek to form Lake Mineral Wells.
