PANTHER MOUNTAIN. Panther Mountain is two miles northwest of Arroyo Segunda in southern Presidio County (at 29°25' N, 103°59' W). Its summit, at an elevation of 4,922 feet above sea level, rises 722 feet above the surrounding desert. It stands in the Bofecillos Mountains, an area characterized by volcanic deposits of lava and ash-flow tuff and sedimentary deposits of conglomerates and sandstones. The topography of the area is desert mountain terrain of steep, rocky land with loose surface rubble. Area vegetation consists primarily of sparse grasses, cacti, and desert shrubs of conifers and oaks. Panther Mountain was named for the wild cats that once inhabited the area.
