Ridgecrest, formerly known as Crumville, was incorporated as a city in 1963. It is located in the Indian Wells Valley in northeastern Kern County, California adjacent to the Naval Air Weapons Station China Lake (NAWS, or China Lake). Ridgecrest is the only incorporated city along US 395 in Kern County. The population was 24,927 at the 2000 census and reached 30,151 in 2008. The city of Ridgecrest is a largely "company" oriented (China Lake, above) community big enough to provide plenty of fine schools, shopping and health care.

Ridgecrest is surrounded by four mountain ranges; the Sierra Nevada on the west, the Cosos on the north, the Argus Range on the east, and the El Paso Mountains on the south. It is approximately 80 miles (130 km) from the Lancaster/Palmdale area and approximately 115 miles (185 km) from both Bakersfield and San Bernardino, the three nearest major urban centers. Air travel in and out of the city is provided through the Inyokern Airport.

Ridgecrest is within two hours of the highest and the lowest points in the continental U.S.[2]



Before this little town was called "Crumville", it was a farming community. The settlement began as Crumville in 1912,[3] honoring James and Robert Crum, local dairymen.[3] The first post office opened in 1941. By 1943, Ridgecrest had grown to 115 homes and 196 residents. NOTS (Naval Ordnance Test Station) was established in November 1943, providing a strong job base for the years to come.[3]

Downtown Ridgecrest, California

Ridgecrest incorporated in 1963.[3] During this era the growth of Ridgecrest was governed by the continuing needs of the high tech industries coupled to the Naval Stations programs for testing arms and guidance systems.


According to the United States Census Bureau, the city has a total area of 20 square miles (52 km2), of which 14 sq mi (36 km2) is land and 0.3 sq mi (1 km2) of it (1.54%) is water.


1995 Ridgecrest earthquake

The area, associated with the Eastern California Shear Zone (ECSZ), has experienced numerous earthquake swarms in the past (groups of several thousand quakes under magnitude 6.0 or so) often with no obvious mainshock. The 1995 Ridgecrest earthquake sequence started on August 17, when a magnitude 5.5 quake, centered 18 kilometers (11 mi) north of the town of Ridgecrest, shook the area and spawned over 2,500 aftershocks over the course of the following five weeks. Then, on September 20, 1995, the second large quake struck the area: it measured magnitude 6.0, and was at that time the largest earthquake to hit southern California since the January 17, 1994 Northridge earthquake.
