Ridgecrest is a city in Kern County, California, United States. Formerly known as Crumville, it was incorporated as a city in 1963. 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.

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.

The settlement began as a faming community called Crumville in 1912, honoring James and Robert Crum, local dairymen. 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.
Ridgecrest incorporated in 1963. 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.

Local features and activities
The most notable feature in the nearby area is the Coso People rock art in Big and Little Petroglyph Canyons. The Coso People were prolific artists and traded with distant tribes using tools crafted of stone. Archeological recovery at coastal Chumash sites in California indicates considerable trade with the Coso People.
Other traditional activities present are:
The Maturango Museum is located in Ridgecrest. The museum is best known for the guided tours on China Lake Naval Weapons Station (NAWS). The Museum offers exhibits and displays featuring both the natural and the cultural history and diversity of the Northern Mojave Desert with exhibits of plants, animals, Native American artifacts, geology and contemporary arts and crafts.
Naval Air Weapons Station China Lake or NAWS China Lake is an airborne weapons testing and training range located adjacent to Ridgecrest and operated by the United States Navy and its contractors. The officer's family housing on base is noted for their monthly 'pig parties' where a lawn ornament in the shape of a pig signaled where the neighborhood would gather for a family grill out. 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.
Coso Rock Art District
Coso Rock Art District, sometimes equated with the Big and Little Petroglyph Canyons is a site containing over 20,000 Native American petroglyphs now located within Naval Air Weapons Station China Lake, near China Lake and Ridgecrest, California. In fact, there are several other distinct canyons to the Coso Rock Art District besides the Big and Little Petroglyph Canyons. The most popular subjects are bighorn sheep, deer, and antelope. Big and Little Petroglyph Canyons were declared a National Historic Landmark in 1964. In 2001, they were incorporated into a larger National Historic Landmark District, called Coso Rock Art District.
