Mojave Desert in the context of "Nevada"

Southern California (commonly shortened to SoCal) is a geographic and cultural region that generally comprises the southern portion of the U.S. state of California. Its densely populated coastal region includes Greater Los Angeles (the second-most populous urban agglomeration in the United States) and San Diego County (the second-most populous county in California). The region generally contains ten of California's 58 counties: Los Angeles, San Diego, Orange, Riverside, San Bernardino, Kern, Ventura, Santa Barbara, San Luis Obispo, and Imperial counties.

Although geographically smaller than Northern California in land area, Southern California has a higher population, with 23.76 million residents as of the 2020 census. The sparsely populated desert region of California occupies a significant portion of the area: the Colorado Desert, along with the Colorado River, is located on Southern California's eastern border with Arizona, and the Mojave Desert shares a border with Nevada to the northeast. Southern California's southern border with Baja California is part of the Mexico–United States border.

Haze is traditionally an atmospheric phenomenon in which dust, smoke, and other dry particulates suspended in air obscure visibility and the clarity of the sky. The World Meteorological Organization manual of codes includes a classification of particulates causing horizontal obscuration into categories of fog, ice fog, steam fog, mist, haze, smoke, volcanic ash, dust, sand, and snow. Sources for particles that cause haze include farming (stubble burning, ploughing in dry weather), traffic, industry, windy weather, volcanic activity and wildfires.Seen from afar (e.g. an approaching airplane) and depending on the direction of view with respect to the Sun, haze may appear brownish or bluish, while mist tends to be bluish grey instead. Whereas haze often is considered a phenomenon occurring in dry air, mist formation is a phenomenon in saturated, humid air. However, haze particles may act as condensation nuclei that leads to the subsequent vapor condensation and formation of mist droplets; such forms of haze are known as "wet haze".

In meteorological literature, the word haze is generally used to denote visibility-reducing aerosols of the wet type suspended in the atmosphere. Such aerosols commonly arise from complex chemical reactions that occur as sulfur dioxide gases emitted during combustion are converted into small droplets of sulfuric acid when exposed. The reactions are enhanced in the presence of sunlight, high relative humidity, and an absence of air flow (wind). A small component of wet-haze aerosols appear to be derived from compounds released by trees when burning, such as terpenes. For all these reasons, wet haze tends to be primarily a warm-season phenomenon. Large areas of haze covering many thousands of kilometers may be produced under extensive favorable conditions each summer.

A desert pavement, also called reg (in western Sahara), serir (in eastern Sahara), gibber (in Australia), or saï (in central Asia) is a desert surface covered with closely packed, interlocking angular or rounded rock fragments of pebble and cobble size. They typically top alluvial fans. Desert varnish collects on the exposed surface rocks over time.

Geologists debate the mechanics of pavement formation and their age.

The Southwestern United States, also known as the American Southwest or simply the Southwest, is a geographic and cultural region of the United States that includes Arizona and New Mexico, along with adjacent portions of California, Colorado, Nevada, Oklahoma, Texas, and Utah. The largest cities by metropolitan area are Phoenix, Las Vegas, El Paso, Albuquerque, and Tucson. Before 1848, in the historical region of Santa Fe de Nuevo México as well as parts of Alta California and Coahuila y Tejas, settlement was almost non-existent outside of New Mexico's pueblos and Spanish or Mexican municipalities. Much of the area had been a part of New Spain and Mexico until the United States acquired the area through the Treaty of Guadalupe Hidalgo in 1848 and the smaller Gadsden Purchase in 1854.

While the region's boundaries are not officially defined, there have been attempts to do so. One such definition is from the Mojave Desert in California in the west (117° west longitude) to Carlsbad, New Mexico, in the east (104° west longitude); another says that it extends from the Mexico–United States border in the south to the southern areas of Colorado, Utah, and Nevada in the north (39° north latitude). In another definition, the core Southwestern U.S. includes only the states of Arizona and New Mexico; others focus on the land within the old Spanish and Mexican borders of the Nuevo México Province or the later American New Mexico Territory.

Red Rock Canyon State Park is a state park in the U.S. state of California which features scenic desert cliffs, buttes and spectacular rock formations. The park consists of approximately 27,000 acres (110 km) within the Mojave Sector of the Tehachapi District of the California State Park System, and is located along State Highway 14 in Kern County, about 80 miles (129 km) east of Bakersfield and 25 miles (40 km) north of Mojave, where the southernmost tip of the Sierra Nevada converges with the El Paso Mountains.

Each tributary canyon is unique, with vivid colors due to alternate layers of white clay and red sandstone, further accented by pink volcanic rocks and brown lava formations. The canyon was formed 3 million years ago. After wet winters, the park's floral displays are notable. Three overlapping desert ecosystems provide for the wildlife that includes eagles, falcons, roadrunners, hawks, coyotes, kit foxes, bobcats, lizards, mice and squirrels. Red Rock Canyon provides magnificent views of the pristine desert landscape, includes two natural preserves, and offers, among other recreational activities, camping, sightseeing, equestrian activities, hiking, and opportunities for solitude.

Sandboarding is a boardsport and extreme sport similar to snowboarding that involves riding down a sand dune while standing on a board, with both feet strapped in. Sand sledding can also be practised sitting down or lying on the belly or the back. It typically involves a sand sled, although it is also somewhat possible to use snow sleds or snowboards. The invention of modern sandboarding is largely attributed to Lon Beale, aka 'Doctor Dune', who began sandboarding in 1972 in California's Mojave Desert.

Sandboarding has adherents throughout the world, but is most prevalent in desert areas or coastal areas with beach dunes. It is less popular than snowboarding, partly because it is very difficult to build a mechanised ski lift on a sand dune, meaning participants must climb or ride a dune buggy or all-terrain vehicle back to the top of the dune. On the other hand, dunes are normally available year-round as opposed to ski resorts, which are seasonal.

Dawn is the time that marks the beginning of twilight before sunrise. It is recognized by the appearance of indirect sunlight being scattered in Earth's atmosphere, when the centre of the Sun's disc has reached 18° below the observer's horizon. This morning twilight period will last until sunrise (when the Sun's upper limb breaks the horizon), when direct sunlight outshines the diffused light.

Kern County is located in the U.S. state of California. As of the 2020 census, the population was 909,235. Its county seat is Bakersfield.

Kern County comprises the Bakersfield, California, metropolitan statistical area. The county spans the southern end of the Central Valley. Covering 8,161.42 square miles (21,138.0 km), it ranges west to the southern slope of the Coast Ranges, and east beyond the southern slope of the eastern Sierra Nevada into the Mojave Desert, at the city of Ridgecrest. Its northernmost city is Delano, and its southern reach extends to just beyond Frazier Park, and the northern extremity of the parallel Antelope Valley.
