Ridgecrest is a city in Kern County, California, United States. It is located along U.S. Route 395 in the Indian Wells Valley in northeastern Kern County, adjacent to the Naval Air Weapons Station China Lake (NAWS, or China Lake). The population was 27,616 at the 2010 census, up from 24,927 at the 2000 census. The city of Ridgecrest is a largely "company" oriented (China Lake, above) community big enough to provide plenty of schools, shopping and health care. It was incorporated as a city in 1963.

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 82 miles (132 km) from the Lancaster/Palmdale area and approximately 145 miles (233 km) from both Bakersfield and San Bernardino, the three nearest major urban centers. Private air travel in and out of the city is provided through the Inyokern Airport. There are currently no scheduled commercial flights in or out of Ridgecrest.

Ridgecrest is within two hours of the highest and the lowest points in the conterminous U.S.[8]


The settlement began as a farming community called Crumville in 1912,[9] honoring James and Robert Crum, local dairymen.[9] 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.[9]

Ridgecrest incorporated in 1963.[9] During this era the growth of Ridgecrest was governed by the continuing needs of the high tech industries coupled to the Naval Station's programs for testing arms and guidance systems.

1995 Ridgecrest earthquake[edit]

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.[citation needed]

The officer's family housing on base is noted for their monthly 'pig parties' where a lawn ornament in the shape of a pig placed by the previous host on another's lawn signaled who the next host would be and the next location for the neighborhood gathering. Each family would bring their meat to burn and a dish to share. At some point during the party, a decision was made to deposit the pig at another home for the location of next month's pig party.
