NUGENT MOUNTAIN. Nugent Mountain is in the Chisos Mountains four miles southeast of the Big Bend National Park headquarters at Panther Junction in southern Brewster County (at 29°16' N, 103°11' W). The mountain, at an elevation of 4,783 feet above sea level, rises 1,650 feet higher than the park road, 1½ miles northeast. Nugent Mountain is a hard mass of intrusive igneous rock that has been exposed by erosion. On its southwest slope are crown-polished boulders that were used by prehistoric people in dressing animal skins. The local soils are shallow to deep sandy loams and support grasses.
