Hidden Hills Lake Test Annex
The former Hidden Hills Lake Test Annex
is located in Inyo County, California approximately 50 miles
west-southwest of Las Vegas, Nevada. The site originally consisted
of 2480 acres. The 2,480 acres of the Hidden Hills Lake Test
Annex were transferred to the US Air Force (USAF) from the U.S.
Department of the Interior through Use Permit LA-1280 dated 9
February 1961, and Special Land Use Permit LA-0168990 dated 13
Hidden Hills Lake Test Annex was used by Edwards AFB as an emergency
landing field and aborted mission area in conjunction with a
continuous tracking radar range. The radar range was capable
of tracking the X-15 research aircraft and obtaining a real time
evaluation of various parameters as they occurred in the aircraft.
No permanent structures were built on the site; all facilities
used at the site were portable.
The 2,480 acres of Hidden Hills Lake Test Annex were retransferred
to the U.S. Department of the Interior on 8 February 1971, pursuant
to the date specified in Special Land Use Permit LA-0168990.
A notice of cancellation of lease was given to the U.S. Department
of the Interior on 12 March 1971, indicating the Department of
the Air Force exercises its rights reserved in said permit and
will quit, relinquish, and give up said premises on 8 February
1971. Currently, the site is controlled by the U.S. Department
of the Interior, Bureau of Land Management (BLM). The site is
undeveloped desert land with most of the site located on a dry
lake bed. No USAF improvements were observed on the site.
