Sierra Nevada in the context of "California"

Photography is the art, application, and practice of creating images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. A person who operates a camera to capture or take photographs is called a photographer, while the captured image, also known as a photograph, is the result produced by the camera.

Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purpose of the photographic material and the method of processing. A negative image on film is traditionally used to photographically create a positive image on a paper base, known as a print, either by using an enlarger or by contact printing.

Granodiorite (/ˌɡrænoʊˈdaɪ.əraɪt, ˌɡrænəˈ-/ GRAN-oh-DY-ə-ryte, GRAN-ə-) is a coarse-grained (phaneritic) intrusive igneous rock similar to granite, but containing more plagioclase feldspar than orthoclase feldspar.

The term banatite is sometimes used informally for various rocks ranging from granite to diorite, including granodiorite. The term granodiorite was first used by G. F. Becker (1893) to describe granitic rocks in the Sierra Nevada, United States.

Nevada (/nəˈvædə/ nə-VAD-ə; Spanish: [neˈβaða] ) is a landlocked state in the Western United States. It is also sometimes placed in the Mountain West and Southwestern United States. It borders Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast, and Utah to the east. Nevada is the seventh-most extensive, the 32nd-most populous, and the ninth-least densely populated U.S. state. Nearly three-quarters of Nevada's population live in Clark County, which contains the Las Vegas–Paradise metropolitan area, including three of the state's four largest incorporated cities. Nevada's capital is Carson City. Las Vegas is the largest city in the state. Nevada is the westernmost U.S. state without coastline and also the westernmost landlocked first-level country subdivison in the Americas.

Nevada is officially known as the "Silver State" because of the importance of silver to its history and economy. It is also known as the "Battle Born State" because it achieved statehood during the Civil War (the words "Battle Born" also appear on its state flag); due to the presidency of Abraham Lincoln, the Union benefited immensely from the support of newly awarded statehood by the infusion of the monetary support of nearly $400 million in silver ore generated at the time by the Comstock Lode. It is also known as the "Sagebrush State", for the native plant of the same name; and as the "Sage-hen State". The state's name means "snowy" in Spanish, referring to Nevada's extensive number of mountain ranges capped with snow in winter, which help make Nevada among the highest US states by mean altitude. These include the Carson Range portion of the Sierra Nevada (and about 1/3 of Lake Tahoe by surface area), as well as the Toiyabe Range, Ruby Mountains, and Spring Mountains (which exemplify the sky islands of the Great Basin montane forests), in western, central, northeastern, and southern Nevada, respectively. Nevada is the driest U.S. state, both lying in the rain shadow of the Sierra Nevada and receiving among the highest solar irradiance of any U.S. state, and is thus largely desert and semi-arid. Nevada comprises the majority of the Great Basin, as well as a large portion of the Mojave Desert. In 2020, 80.1% of the state's land was managed by various jurisdictions of the U.S. federal government, both civilian and military.

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.

Lake Tahoe (/ˈtɑːhoʊ/) is a freshwater lake in the Sierra Nevada of the Western United States, straddling the border between California and Nevada. Lying at 6,225 ft (1,897 m) above sea level, Lake Tahoe is the largest alpine lake in North America, and at 122,160,280 acre⋅ft (150.7 km) it trails only the five Great Lakes as the largest by volume in the United States. Its depth is 1,645 ft (501 m), making it the second deepest in the United States after Crater Lake in Oregon (1,949 ft or 594 m).

The lake was formed about two million years ago as part of the Lake Tahoe Basin, and its modern extent was shaped during the ice ages. It is known for the clarity of its water and the panorama of surrounding mountains on all sides. The area surrounding the lake is also referred to as Lake Tahoe, or simply Tahoe; its English name is derived from its Washo name, Dáʔaw. More than 75% of the lake's watershed is national forest land, covered by the Lake Tahoe Basin Management Unit of the United States Forest Service.

Yosemite National Park (/joʊˈsɛmɪti/ yoh-SEM-ih-tee) is a national park of the United States in California. It is bordered on the southeast by the Sierra National Forest and on the northwest by Stanislaus National Forest. The park is managed by the National Park Service and covers 1,187 sq mi (3,070 km) in four counties – centered in Tuolumne and Mariposa, extending north and east to Mono and south to Madera. Designated a World Heritage Site in 1984, Yosemite is internationally recognized for its granite cliffs, waterfalls, clear streams, groves of giant sequoia, lakes, mountains, meadows, glaciers, and biological diversity. Almost 95 percent of the park is designated wilderness. Yosemite is one of the largest and least fragmented habitat blocks in the Sierra Nevada mountain range.

Its geology is characterized by granite and remnants of older rock. About 10 million years ago, the Sierra Nevada was uplifted and tilted to form its unique slopes, which increased the steepness of stream and river beds, forming deep, narrow canyons. About one million years ago, glaciers formed at higher elevations. They moved downslope, cutting and sculpting the U-shaped Yosemite Valley.

San Francisco Bay is a large tidal estuary in the U.S. state of California, and gives its name to the San Francisco Bay Area. It is dominated by the cities of San Francisco, San Jose, and Oakland.

San Francisco Bay drains water from approximately 40 percent of California. Water from the Sacramento and San Joaquin rivers, and from the Sierra Nevada mountains, flow into Suisun Bay, which then travels through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. It then connects to the Pacific Ocean via the Golden Gate strait. However, this entire group of interconnected bays is often called San Francisco Bay. The bay was designated a Ramsar Wetland of International Importance on February 2, 2013, and the Port of Oakland on the bay is one of the busiest cargo ports on the west coast.

Interstate 80 (I-80) is a transcontinental Interstate Highway in the United States, stretching from San Francisco, California, to Teaneck, New Jersey. The segment of I-80 in California runs east from San Francisco across the San Francisco–Oakland Bay Bridge to Oakland, where it turns north and crosses the Carquinez Bridge before turning back northeast through the Sacramento Valley. I-80 then traverses the Sierra Nevada, cresting at Donner Summit, before crossing into the state of Nevada within the Truckee River Canyon. The speed limit is at most 65 mph (105 km/h) along the entire route instead of the state's maximum of 70 mph (110 km/h) as most of the route is in either urban areas or mountainous terrain. I-80 has portions designated as the Eastshore Freeway and Alan S. Hart Freeway.

Throughout California, I-80 was built along the corridor of US Route 40 (US 40), eventually replacing this designation entirely. The prior US 40 corridor itself was built along several historic corridors in California, notably the California Trail and Lincoln Highway. The route has changed from the original plans in San Francisco due to freeway revolts canceling segments of the originally planned alignment. Similarly in Sacramento, the freeway was rerouted around the city after plans to upgrade the original grandfathered route through the city to Interstate Highway standards were canceled.
