HEELTAP BRANCH. Heeltap Branch rises about four miles southeast of Clarksville in south central Red River County (at 33°34' N, 95°00' W) and runs southeast for seven miles to its mouth on Burkhand Branch, seven miles north of the Sulphur River (at 33°29' N, 94°57' W). Most of the local soil is clayey; near the mouth of the creek, however, there are bands of fine sandy loam on either side. The area is heavily agricultural, with pastureland and fields interspersed with some heavily wooded areas. Originally the local timber comprised a wide variety of hardwoods, including oak, ash, walnut, and hickory, but in the mid-1980s post and blackjack oaks predominated.
