These unusual rolling hills and sand washes, located 10 miles west of Hwy. 86 on Hwy. 78, are designated "Open Area D" by the BLM. The area consists of 4,800 acres adjacent to Ocotillo Wells Vehicular Recreation Area. Part of the area was used for training by the Army Tank Corps in the early part of World War II. The area has been cleared of most dangerous material, but it is still possible to find old ammo buried in the sand. Anything found should be left alone and reported to the BLM or Rangers in the area.
