The former Mirage Lake Glider School was located at El Mirage Dry Lake about 14 miles west of Adelanto and 18 miles northwest of Victorville, San Bernardino County. The US Army Air Forces acquired 1,292.72 acres of public domain land from the Department of the Interior by Public Land Order No. 110, dated 14 April 1943. The remaining 644.19 acres acquired were privately owned land and were leased by the War Department.
The mirage Lake Glider School site was used as an advanced glider training school for the Victorville Army Flying School (Victorville Army Air Field and later George Air Force Base). According to the Corps of Engineers, letter dated 6 December, 1946, there were no War Department constructed improvements on this land.
The Army declared the Mirage Lake Glider School land surplus to the requirements of the war Department. A letter dated 6 December 1946 from the Army to the BLM stated that there are no War Department constructed improvements on this land and restoration thereof is not required. The transferred 1,292.72-acre area was disposed of by relinquishment to the Department of the Interior, effective 6 December, 1946, and retransferred by Public Land order No. 529 dated 24 November 1948. The leases totaling 644.19 acres were canceled during the period of 17 July 1946 through 2 September 1946. Approximately 1,298 acres of the land is presently managed by the Bureau of Land Management. The BLM land is open area for recreation use (i.e., off-road vehicles). The remaining land has been subdivided and belongs to private individuals. The private land has not been developed.
