PANTHER CANYON. Panther Canyon, a valley traversed by an intermittent stream with the same name, rises near Panther Spring 2½ miles southeast of Panther Mountain in southeastern Presidio County (at 29°23' N, 103°57' W) and runs south for eight miles to its mouth on the Rio Grande, eleven miles west of the Brewster county line (at 29°19' N, 103°58' W). Its course crosses the volcanic tuff, flows off the Bofecillos Mountains area immediately west of Santana Mesa, and terminates in the gravel terrace of the Rio Grande floodplain. The soils in the area are generally light reddish-brown to brown sands and clay loams, often rough and stony. The vegetation consists primarily of sparse desert shrubs. The canyon and creek were named for Panther Mountain.
