GEMELO MESA. Gemelo Mesa is 1½ miles northeast of Cartwright Mesa in east central Presidio County (at 29°59' N, 103°52' W). Gemelo Mesa's top, at an elevation of 5,065 feet above sea level, rises 833 feet above the unpaved road at its base. The mesa stands in the area of Paradise Valley and is composed of volcanic deposits of welded tuffs and conglomerates. The surrounding area is desert mountain terrain and rugged canyonland with loose surface rubble. Local vegetation includes sparse grasses, cacti, and desert shrubs of conifers and oaks. Gemelo Mesa is made up of two similar-sized buttes; gemelo is Spanish for "twin."
