California Coast Ranges in the context of "Salinas River (California)"

The Central Valley is a broad, elongated, flat valley that dominates the interior of California, United States. It is 40–60 mi (60–100 km) wide and runs approximately 450 mi (720 km) from north-northwest to south-southeast, inland from and parallel to the Pacific coast. It covers approximately 18,000 sq mi (47,000 km), about 11% of California's land area. The valley is bounded by the Coast Ranges to the west and the Sierra Nevada to the east.

The Central Valley is a region known for its agricultural productivity. It provides a large share of the food produced in California, which provides more than half of the fruits, vegetables, and nuts grown in the United States. More than 7,000,000 acres (28,000 km) of the valley are irrigated via reservoirs and canals. The valley hosts many cities, including the state capital Sacramento, as well as Redding, Chico, Yuba City, Woodland, Davis, Roseville, Elk Grove, Stockton, Modesto, Merced, Fresno, Visalia, Porterville, and Bakersfield.

San Benito County (/ˌsæn bəˈniːtoʊ/ ; San Benito, Spanish for "St. Benedict"), officially the County of San Benito, is a county located in the Central Coast region of California. Situated in the California Coast Ranges, the county had a population of 64,209, as of the 2020 United States census. The county seat is the city of Hollister.

San Benito County is included in the San Jose-Sunnyvale-Santa Clara, CA Metropolitan Statistical Area, which is also included in the San Jose-San Francisco-Oakland, CA Combined Statistical Area. El Camino Real passes through the county and includes one mission in San Juan Bautista.

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.

Central California is generally thought of as the middle third of the U.S. state of California, north of Southern California (which includes Los Angeles and San Diego) and south of Northern California (which includes San Francisco and San Jose). It includes the northern portion of the San Joaquin Valley (which itself is the southern portion of the Central Valley, beginning at the Sacramento–San Joaquin River Delta), part of the Central Coast, the central hills of the California Coast Ranges and the foothills and mountain areas of the central Sierra Nevada.

Central California is considered to be west of the crest of the Sierra Nevada. East of the Sierra is Eastern California. The largest cities in the region (over 50,000 population), from most to least populous, are Sacramento, Fresno, Bakersfield, Stockton, Modesto, Elk Grove, Salinas, Visalia, Clovis, Tracy, Merced, Manteca, Turlock, Tulare, Madera, Lodi, Porterville, Santa Cruz, Hanford, and Delano. Over time, droughts and wildfires have increased in frequency and become less seasonal and more year-round, further straining the region's water security.

Mendocino County (/ˌmɛndəˈsiːnoʊ/ ; Mendocino, Spanish for "of Mendoza") is a county located on the North Coast of the U.S. state of California. As of the 2020 United States census, the population was 91,601. The county seat is Ukiah.

Mendocino County consists wholly of the Ukiah, California Micropolitan Statistical Area (μSA) for the purposes of the U.S. Census Bureau. It is located approximately equidistant from the San Francisco Bay Area and California/Oregon border, separated from the Sacramento Valley to the east by the California Coast Ranges. While smaller areas of redwood forest are found farther south, it is the southernmost California county to be included in the World Wildlife Fund's Pacific temperate rainforests ecoregion, the largest temperate rainforest ecoregion on Earth.

The Transverse Ranges are a group of mountain ranges of Southern California, in the Pacific Coast Ranges physiographic region in North America. The Transverse Ranges begin at the southern end of the California Coast Ranges and lie within Santa Barbara, Ventura, Los Angeles, San Bernardino, Riverside and Kern counties. The Peninsular Ranges lie to the south. The name is due to the ranges' east–west orientation, making them transverse to the general northwest–southeast orientation of most of California's coastal mountains.

The ranges extend from west of Point Conception eastward approximately 500 kilometers into the Mojave and Colorado Desert. The geology and topography of the ranges express three distinct segments that have contrasting elevations, rock types, and vegetation. The western segment extends to the San Gabriel Mountains and San Gabriel fault. The central segment includes mountains that range eastward to the San Andreas fault. The eastern segment extends from the Cajon Pass at the San Andreas fault eastward to the Colorado Desert. The central and eastern segments (near the San Andreas fault) have the highest elevations.

The Sacramento River (Spanish: Río Sacramento) is the principal river of Northern California in the United States and is the largest river in California. Rising in the Klamath Mountains, the river flows south for 400 miles (640 km) before reaching the Sacramento–San Joaquin River Delta and San Francisco Bay. The river drains about 26,500 square miles (69,000 km) in 19 California counties, mostly within the fertile agricultural region bounded by the Coast Ranges and Sierra Nevada known as the Sacramento Valley, but also extending as far as the volcanic plateaus of Northeastern California. Historically, its watershed has reached as far north as south-central Oregon where the now, primarily, endorheic (closed) Goose Lake rarely experiences southerly outflow into the Pit River, the most northerly tributary of the Sacramento.

The Sacramento and its wide natural floodplain were once abundant in fish and other aquatic creatures, notably one of the southernmost large runs of chinook salmon in North America. For about 12,000 years, humans have depended on the vast natural resources of the watershed, which had one of the densest Native American populations in California. The river has provided a route for trade and travel since ancient times. Hundreds of tribes sharing regional customs and traditions have inhabited the Sacramento Valley, first coming into contact with European explorers in the late 1700s. The Spanish explorer Gabriel Moraga named the river Rio de los Sacramentos in 1808, later shortened and anglicized into Sacramento.

The August Complex fire was a massive wildfire complex that burned in the Coast Range of Northern California, in Glenn, Lake, Mendocino, Tehama, Trinity, and Shasta Counties. The complex originated as 38 separate fires started by lightning strikes on August 16–17, 2020. Four of the largest fires, the Doe, Tatham, Glade, and Hull fires, had burned together by August 30. On September 9, the Doe Fire, the main fire of the August Complex, surpassed the 2018 Mendocino Complex to become both the single-largest wildfire and the largest fire complex in recorded California history. On September 10, the combined Doe Fire also merged with the Elkhorn Fire (originally a separate incident) and the Hopkins Fire, growing substantially in size. By the time it was extinguished on November 12, the August Complex fire had burned a total of 1,032,648 acres (417,898 ha), or 1,614 square miles (4,180 km), about 1% of California's 100 million acres of land, an area larger than the state of Rhode Island.

The fire largely burned within the Mendocino National Forest, with portions spilling over to the Shasta-Trinity National Forest and Six Rivers National Forest in the north, as well as private land surrounding the forests. Large areas of the Yolla Bolly-Middle Eel Wilderness and Yuki Wilderness had also been burned. Rugged terrain combined with consistent high winds and record heat had complicated firefighting efforts. Although more than 2,900 personnel were deployed to the fire through mid-September, it took almost three months to fully contain the fire. The U.S. Forest Service managed the firefighting effort, with assistance from the California Department of Forestry and Fire Protection.

The Wintun are members of several related Native American peoples of Northern California, including the Wintu (northern), Nomlaki (central), and Patwin (southern). Their range is from approximately present-day Lake Shasta to San Francisco Bay, along the western side of the Sacramento River to the Coast Range. Each of these tribes speak one of the Wintuan languages. Linguistic and archaeological evidence suggests that the Wintun people probably entered the California area around 500 AD from what is now southern Oregon, introducing bow and arrow technology to the region (Golla 2011: 205). There has been carbon dating of several artifacts by UC Berkeley that dates back to around 10,000 years, and several of these artifacts have now been repatriated. Despite being a major influence on the region's history, there is still very little history on the Wintu due to centuries of genocide and displacement that still occur today along with continued destruction of sacred ceremonial and religious sites, often due to companies that ignore legal or ethical considerations.
