LA VIUDA MOUNTAIN. La Viuda Mountain is two miles northwest of Tascotal Mesa in east central Presidio County (at 29°43' N, 103°59' W). With an elevation of 4,080 feet above sea level, its summit rises 420 feet above the Marfa-Lajitas Road at the east edge of the mesa. La Viuda is an intrusion of volcanic basalt surrounded by sedimentary deposits of sandstones and conglomerates in the Alamito Creek valley. The topography of the area is desert mountain terrain and rugged canyonland with loose surface rubble. Vegetation consists primarily of sparse grasses, cacti, and desert shrubs of conifers and oaks. Viuda is Spanish for "widow."
