JORDAN GAP. Jordan Gap is 5½ miles east of Alamito Creek in east central Presidio County (at 29°57' N, 103°55' W). The gap, at an elevation of 4,424 feet above sea level, rises 134 feet above nearby Paradise Valley. It stands in the area of Cartwright Mesa, characterized by desert mountain terrain and canyonland of volcanic deposits. The land surface includes light reddish-brown to brown sand, clay loam, and rough stony areas. Local vegetation comprises sparse grasses, cacti, and desert shrubs of conifers and oaks. Jordan Gap was named for the Jordan family, early settlers in Presidio County.
