The Sierra Vieja mountains are forty-two miles northwest of Marfa in western Jeff Davis and northwestern Presidio counties (centered at 30°27' N, 104°40' W). They extend sixteen miles south from just east of the Van Horn Mountains and four miles southwest of Chispa, U.S. Highway 90, and the Southern Pacific Railroad. The highest elevation in the Sierra Vieja is 6,450 feet above sea level, some 2,700 feet above the Coal Mine Ranch, four miles west. Shallow, stony soils in the Sierra Vieja support live oak, piñon pine, juniper, and grasses. Sierra Vieja is Spanish for "old mountains."
