CASTLE MOUNTAIN (Crane and Upton counties). Castle Mountain, on the Crane-Upton county line six miles south of Crane (at 31°18' N, 102°17' W), reaches an elevation of 3,151 feet at its summit. The mountain received its name from early Spanish explorers who thought it resembled a castle. It is composed of limestone and calcareous clay mud substrate with shallow, dark clay soil. Juniper, oak, grasses, chaparral, and cacti grow on it. Castle Gap divides Castle Mountain and is a landmark and spring-fed watering place that has been used by travelers for centuries. In 1968 a 100-acre park at Castle Gap was given to Upton County by the family of Caton Jacobs, owner of the property since the 1930s.
