High Desert is a vernacular region with non-discrete boundaries applying to areas of the western Mojave Desert in southern California. The "High Desert" region is an area that generally is situated between 2,000 feet (610 m) and 4,000 feet (1,200 m) in elevation, and located just north of the San Gabriel, San Bernardino, and Little San Bernardino Mountains.

The term "High Desert" is commonly used by local news media,^[1] especially in weather forecasts, because of the high desert's unique and moderate weather patterns compared to its low desert neighbors. It generally gets much hotter in the summer and much colder in the winter than the lower elevation areas closer to the coast and in the lower valleys.^[2][3] The term "High Desert" serves to differentiate it from southern California's Low Desert, which is defined by the differences in elevation, climate, animal life, and vegetation native to these regions. Comparison example: Palm Springs is considered "Low Desert", at 500 feet (150 m) above sea level. In contrast, Landers is considered "High Desert", at 3,100 feet (940 m) above sea level.

The High Desert, along with the "Mojave River Valley" and the Victor Valley, is mostly used to describe the area centered around Victorville. The region extends as far west as Lancaster, as far northwest as Palmdale, and north to the Barstow desert.^[3] High Desert has also been incorporated into the names of businesses and organizations in these areas.^[4][5] The term "High Desert" is also used to refer to the communities north and west of Joshua Tree National Park - Twentynine Palms the Morongo Basin (Yucca Valley). These are also at a higher elevation than the Low Desert that surrounds the Coachella Valley and Imperial Valley.

Geography

Depending on how the boundaries of the Mojave and the Colorado Desert region are defined, the High Desert either includes the entire California portion of the Mojave Desert (using a smaller geographic designation than its ecoregion) or the northern portion of the California desert (using a larger geographic designation including the ecotope area of the lower and adjacent Sonoran Desert).

The name of the region comes from its higher elevations and more northern latitude with associated climate and plant communities distinct from the Low Desert, which includes the Colorado Desert and the below sea level Salton Sea. The High Desert is typically windier than the Low Desert, and averages between 12 degrees to 20 degrees Fahrenheit cooler in both the winter and summer seasons.

Regions

The High Desert is often divided into the following regions, moving west to east:

• The Los Angeles County portion, containing the Antelope Valley, part of the Palmdale-Lancaster Urbanized Area, and in the greater Los Angeles metropolitan area. The Lancaster—Palmdale, CA Urbanized Area is home to 353,619 people.^[6]
• The San Bernardino County portion, containing the Victor Valley is the most populous region of the High Desert with an estimated 2015 population of over 385,960 residents.^[7] Major population center in area includes Victorville, Hesperia, Apple Valley, Adelanto, and Oak Hills. This region is sometimes considered part of the Inland Empire area of Southern California.
• Further east lies the Lucerne Valley and the Morongo Basin, where Yucca Valley and the Twentynine Palms Marine Base are located. All these regions are all considered to be part of the Greater Los Angeles Area.

San Bernardino County's portion of the High Desert region contains the most land mass of the four involved counties, making up approximately 70% of the total county's area.

Other parts of the greater physical region known as the "High Desert" include:

• The San Bernardino County northeastern reaches of the High Desert, where the Fort Irwin National Training Center and the Searles Valley are located, and the far eastern edge of the state where places like Needles and Earp are located along the Colorado River.
• The Kern County portion, containing part of two valleys, with the southeastern part in the Antelope Valley, including Rosamond, California City, Boron, Edwards Air Force Base, and Mojave, which are all a part of the Palmdale-Lancaster Urbanized area, and the northeastern part being in the Indian Wells Valley, including the communities of Inyokern and Ridgecrest.
• The Inyo County portion, north of Kern County and containing the northern end of the Indian Wells Valley, Panamint Valley, and Saline Valley. This is the most sparsely populated area of the High Desert, with a single major community, Lone Pine in the southern Owens Valley.

Cities and communities

The major metropolitan centers in the region are primarily centered on the cities of Lancaster and Victorville. Lancaster, the largest city in the High Desert, is located in the Antelope Valley next to Palmdale and anchors the area's Los Angeles County region with a metro area of just over 500,000. The Victor Valley area, which includes cities and communities such as Victorville, Hesperia, Adelanto, Apple Valley, and Lucerne Valley, boasts a population around 385,000.^[8] The Barstow area, to the north of Victor Valley, and the Morongo Basin near Joshua Tree National Park both have populations of around 60,000.
