The Sierra Nevada (/ / or //, Spanish: [ˈsjera neˈβaða], snowy range) is a mountain range in the western United States, between the Central Valley of California and the Basin and Range Province. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada.
The Sierra runs 400 miles (640 km) north-to-south, and is approximately 70 miles (110 km) across east-to-west. Notable Sierra features include Lake Tahoe, the largest alpine lake in North America; Mount Whitney at 14,505 ft (4,421 m), the highest point in the contiguous United States; and Yosemite Valley sculpted by glaciers out of 100-million-year-old granite. The Sierra is home to three national parks, 20 wilderness areas, and two national monuments. These areas include Yosemite, Sequoia, and Kings Canyon National Parks; and Devils Postpile National Monument.
The character of the range is shaped by its geology and ecology. More than 100 million years ago during the Nevadan orogeny, granite formed deep underground. The range started to uplift 4 Ma (million years) ago, and erosion by glaciers exposed the granite and formed the light-colored mountains and cliffs that make up the range. The uplift caused a wide range of elevations and climates in the Sierra Nevada, which are reflected by the presence of five life zones. Uplift continues due to faulting caused by tectonic forces, creating spectacular fault block escarpments along the eastern edge of the southern Sierra.
The Sierra Nevada has a significant history. The California Gold Rush occurred in the western foothills from 1848 through 1855. Due to inaccessibility, the range was not fully explored until 1912.:81

The Sierra Nevada lies in Central and Eastern California, with a very small but historically important spur extending into Nevada. The range is extremely steep, rising from 1,000 feet (300 m) in the west to an average height of about 10,500 feet (3,200 m) at its crest only 50–75 miles (80–121 km) to the east. Unlike its surroundings, the range receives a substantial amount of snowfall and precipitation due to orographic lift. Environments at higher elevations from 6,000 feet (1,800 m) up to the tree line tend to be wet and marshy. Donner Pass is known as one of the snowiest places in the United States.
The Sierra Nevada stretches from the Susan River and Fredonyer Pass in the north to Tehachapi Pass in the south. It is bounded on the west by California's Central Valley and on the east by the Basin and Range Province.
The geographical boundary between the Sierra and the Cascades is virtually indistinguishable, with the Fredonyer Pass designation being traditional. Physiographically, the Sierra is a section of the Cascade-Sierra Mountains province, which in turn is part of the larger Pacific Mountain System physiographic division.
West-to-east, the Sierra Nevada's elevation increases gradually from the Central Valley to the crest, while the east slope forms the steep Sierra Escarpment. The range is drained on its north-west slopes by the Sacramento River and to the west-southwest by the San Joaquin River, two major Central Valley watercourses that ultimately discharge to the Pacific Ocean. Smaller rivers of the west slope include the Feather, Yuba, American, Mokelumne, Stanislaus and Tuolumne. The southern part of the mountains are drained by four rivers called the Kings, Kaweah, Tule, and Kern. These rivers flow into an endorheic basin called Tulare Lake, but historically joined the San Joaquin during wet years.
To the east, the melting snow of the mountains forms many small rivers that flow out into the Great Basin of Nevada and eastern California. From north to south, the Susan River flows into intermittent Honey Lake; the Truckee River flows from massive Lake Tahoe into Pyramid Lake; the Carson River runs into Carson Sink; the Walker River into Walker Lake; Rush, Lee Vining and Mill Creeks into Mono Lake; and the Owens River into the dry Owens Lake. None of the east-side rivers reach the sea; however, many of the streams from Mono Lake southwards are diverted into the Los Angeles Aqueduct and their water shipped to Southern California.
The height of the mountains in the Sierra Nevada increases gradually from north to south. Between Fredonyer Pass and Lake Tahoe, the peaks range from 5,000 feet (1,500 m) to more than 9,000 feet (2,700 m). The crest near Lake Tahoe is roughly 9,000 feet (2,700 m) high, with several peaks approaching the height of Freel Peak (10,881 ft or 3,317 m). Further south, the highest peak in Yosemite National Park is Mount Lyell (13,120 ft or 3,999 m). The Sierra rise to almost 14,000 feet (4,300 m) with Mount Humphreys near Bishop, California. Finally, near Lone Pine, Mount Whitney is at 14,505 feet (4,421 m), the highest point in the contiguous United States.
South of Mount Whitney, the range quickly dwindles. The crest elevation is almost 10,000 feet (3,000 m) near Lake Isabella, but south of the lake, the peaks reach only to a modest 8,000 feet (2,400 m).
There are several notable geographical features in the Sierra Nevada:
- Lake Tahoe is a large, clear freshwater lake in the northern Sierra Nevada, with an elevation of 6,225 ft (1,897 m) and an area of 191 sq mi (490 km2). Lake Tahoe lies between the main Sierra and the Carson Range, a spur of the Sierra.
- Hetch Hetchy Valley, Yosemite Valley, Kings Canyon, and Kern Canyon are examples of many glacially-scoured canyons on the west side of the Sierra.
- Yosemite National Park is filled with notable features, such as waterfalls and granite domes.
- Groves of Giant Sequoias Sequoiadendron giganteum occur along a narrow band of altitude on the western side of the Sierra Nevada. Giant sequoias are the largest trees in the world.
- The two largest rivers in California, which form the Central Valley and drain into San Francisco Bay, derive most of their flow from the western slopes of the Sierra Nevada range. The northern of the two is the Sacramento River (which also drains the adjacent Cascade Range and Klamath Range); the more southern is the San Joaquin River.
Much of the Sierra Nevada consists of federal lands and is either protected from development or is strictly managed. The three National Parks (Yosemite, Kings Canyon, Sequoia), two National Monuments (Devils Postpile, Giant Sequoia), and 20 wilderness areas lie within the Sierra. These areas protect 15.4% of the Sierra's 63,118 km2 (24,370 sq mi) from logging and grazing.
The United States Forest Service and the Bureau of Land Management currently control 52% of the land in the Sierra Nevada. Logging and grazing is generally allowed on land controlled by these agencies, under federal regulations that balance recreation and development on the land.
The California Bighorn Sheep Zoological Area near Mount Williamson in the southern Sierra was established to protect the endangered Sierra Nevada bighorn sheep. Starting in 1981, hikers were unable to enter the Area from May 15 through December 15, in order to protect the sheep. As of 2010, the restriction has been lifted and access to the Area is open for the whole year.
The earliest rocks in the Sierra Nevada are metamorphic roof pendants of Paleozoic age, the oldest rocks being metasedimentary rocks from the Cambrian in the Mount Morrison region. They are dark colored hornfels, slates, marbles, and schists, and are found in the western foothills (notably around Coarsegold and west of the Tehachapi Pass) and also east of the Sierra Crest. The earliest granite of the Sierra started to form in the Triassic period. This granite is mostly found east of the crest and north of 37.2°N. In the Triassic and into the Jurassic, an island arc collided with the west coast of North America and raised a chain of volcanoes, in an event called the Nevadan orogeny. Nearly all subaerial Sierran Arc volcanoes have since disappeared; their remains were redeposited during the Great Valley Sequence and the subsequent Cenozoic filling of the Great Valley, which is the source of much of the sedimentary rock in California.
In the Cretaceous, a subduction zone formed at the edge of the continent. This means that an oceanic plate started to dive beneath the North American plate. Magma formed through the subduction of the ancient Farallon Plate rose in plumes (plutons) deep underground, their combined mass forming what is called the Sierra Nevada batholith. These plutons formed at various times, from 115 Ma to 87 Ma. The earlier plutons formed in the western half of the Sierra, while the later plutons formed in the eastern half of the Sierra. By 66 Ma, the proto-Sierra Nevada had been worn down to a range of rolling low mountains, a few thousand feet high.
Twenty million years ago, crustal extension associated with the Basin and Range Province caused extensive volcanism in the Sierra. About 10 Ma, the Sierra Nevada started to form: a block of crust between the Coast Range and the Basin and Range Province started to tilt to the west. Rivers started cutting deep canyons on both sides of the range. Lava filled some of these canyons, which have subsequently eroded leaving table mountains that follow the old river channels.
About 2.5 Ma, the Earth's climate cooled, and ice ages started. Glaciers carved out characteristic U-shaped canyons throughout the Sierra. The combination of river and glacier erosion exposed the uppermost portions of the plutons emplaced millions of years before, leaving only a remnant of metamorphic rock on top of some Sierra peaks.
Climate and meteorology
The climate of the Sierra Nevada is influenced by the Mediterranean climate of California. During the fall, winter and spring, precipitation in the Sierra ranges from 20 to 80 in (510 to 2,030 mm) where it occurs mostly as snow above 6,000 ft (1,800 m). Precipitation is highest on the central and northern portions of the western slope between 5,000 and 8,000 feet (1,500 and 2,400 m) elevation, due to orographic lift.:69 Above 8,000 feet (2,400 m), precipitation diminishes on the western slope up to the crest, since most of the precipitation has been wrung out at lower elevations. Most parts of the range east of the crest are in a rain shadow, and receive less than 25 inches of precipitation per year. Summers are dry with low humidity; however, afternoon thunderstorms are common, particularly during the North American Monsoon. Summer high temperatures average 42–90 °F (6–32 °C). Winters are comparatively mild, and the temperature is usually only just low enough to sustain a heavy snowpack; winter high temperatures at elevation average 35–15 °F (2 – −9 °C), and rarely dip below 0 °F (−18 °C). The growing season lasts 20 to 230 days, strongly dependent on elevation. The highest elevations of the Sierra have an alpine climate.
The Sierra Nevada snowpack is the major source of water and a significant source of electric power generation in California. Many reservoirs were constructed in the canyons of the Sierra throughout the 20th century, Several major aqueducts serving both agriculture and urban areas distribute Sierra water throughout the state. However, the Sierra casts a rain shadow, which greatly affects the climate and ecology of the central Great Basin. This rain shadow is largely responsible for Nevada being the driest state in the United States.
Precipitation varies substantially from year to year. It is not uncommon for some years to receive precipitation totals far above or below normal. Since 2012, the range has been in a dry spell, contributing heavily to drought conditions throughout the state.
The height of the range and the steepness of the Sierra Escarpment, particularly at the southern end of the range produces a wind phenomenon known as the "Sierra Rotor". This is a horizontal rotation of the atmosphere just east of the crest of the Sierra, set in motion as an effect of strong westerly winds.
The Sierra Nevada is divided into a number of biotic zones, each of which is defined by its climate and supports a number of interdependent species. Life in the higher elevation zones adapted to colder weather, and to most of the precipitation falling as snow. The rain shadow of the Sierra causes the eastern slope to be warmer and drier: each life zone is higher in the east. A list of biotic zones, and corresponding elevations, is presented below:
- The western foothill zone, 500–3,500 ft (150–1,070 m), with grassland, oak-grass savanna and chaparral-oak woodland. North of Sequoia National Park, Gray pine (also known as digger pine) is intermixed with the oak woodland.:95
- The Pinyon pine-Juniper woodland, 5,000–7,000 ft (1,500–2,100 m) east side only.
- The Sierra Nevada lower montane forest (indicator species: Ponderosa pine, Jeffrey pine), 3,000–7,000 ft (910–2,130 m) west side, 7,000–8,500 ft (2,100–2,600 m) east side. This biotic zone is notable for containing Giant Sequoia.
- The upper montane forest (indicator species: Lodgepole pine, Red fir), 7,000–9,000 ft (2,100–2,700 m) west side, 8,500–10,500 ft (2,600–3,200 m) east side
- The Sierra Nevada subalpine zone (indicator species: Whitebark pine) 9,000–10,500 ft (2,700–3,200 m) west side, 10,500–11,500 ft (3,200–3,500 m) east side
- The alpine region at greater than 10,500 ft (3,200 m), and greater than 11,500 ft (3,500 m) east side
Archaeological excavations placed Martis people of Paleo-Indians in northcentral Sierra Nevada during the period of 3,000 BCE to 500 CE. The earliest identified sustaining indigenous people in the Sierra Nevada were the Northern Paiute tribes on the east side, with the Mono tribe and Sierra Miwok tribe on the western side, and the Kawaiisu and Tubatulabal tribes in the southern Sierra. Today, some mountain passes, such as Duck Pass with obsidian arrowheads, are artifact locations from historic intertribal trade route trails. The California and Sierra Native American tribes were predominantly peaceful, with occasional territorial disputes between the Paiute and Sierra Miwok tribes in the mountains. Washo and Maidu were also in this area prior to the era of European exploration and displacement.
Used in 1542 by Juan Rodríguez Cabrillo to describe a Pacific Coast Range (Santa Cruz Mountains), the term "sierra nevada" was a general identification of less familiar ranges toward the interior. In 1777, Pedro Font's map applied the name to the range currently known as the Sierra Nevada.
The literal translation is "snowy mountains," from sierra "a range of hills," 1610s, from Spanish sierra "jagged mountain range," lit. "saw," from Latin serra "a saw"; and from fem. of Spanish nevado "snowy."
Initial European-American exploration
European-American exploration of the mountain range started in 1827. Although prior to the 1820s there were Spanish missions, pueblos (towns), presidios (forts), and ranchos along the coast of California, no Spanish explorers visited the Sierra Nevada. The first European Americans to visit the mountains were amongst a group led by fur trapper Jedediah Smith, crossing north of the Yosemite area in May 1827, at Ebbetts Pass.
In 1833, a subgroup of the Bonneville Expedition led by Joseph Reddeford Walker was sent westward to find an overland route to California. Eventually the party discovered a route along the Humboldt River across present-day Nevada, ascending the Sierra Nevada, starting near present day Bridgeport and descending between the Tuolumne and Merced River drainage. The group may have been the first non-indigenous people to see Yosemite Valley. The Walker party probably visited either the Tuolumne or Merced Groves of Giant Sequoia, becoming the first non-indigenous people to see the giant trees, but journals relating to the Walker party were destroyed in 1839, in a print shop fire in Philadelphia.
The California Gold Rush began at Sutter's Mill, near Coloma, in the western foothills of the Sierra. On January 24, 1848 James W. Marshall, a foreman working for Sacramento pioneer John Sutter, found shiny metal in the tailrace of a lumber mill Marshall was building for Sutter on the American River. Rumors soon started to spread and were confirmed in March 1848 by San Francisco newspaper publisher and merchant Samuel Brannan. Brannan strode through the streets of San Francisco, holding aloft a vial of gold, shouting "Gold! Gold! Gold from the American River!"
On August 19, 1848, the New York Herald was the first major newspaper on the East Coast to report the discovery of gold. On December 5, 1848, President James Polk confirmed the discovery of gold in an address to Congress.:80 Soon, waves of immigrants from around the world, later called the "forty-niners", invaded the Gold Country of California or "Mother Lode". Miners lived in tents, wood shanties, or deck cabins removed from abandoned ships. Wherever gold was discovered, hundreds of miners would collaborate to put up a camp and stake their claims.
Because the gold in the California gravel beds was so richly concentrated, the early forty-niners simply panned for gold in California's rivers and streams.:198-200 However, panning cannot take place on a large scale, and miners and groups of miners graduated to more complex placer mining. Groups of prospectors would divert the water from an entire river into a sluice alongside the river, and then dig for gold in the newly exposed river bottom.:90
By 1853, most of the easily accessible gold had been collected, and attention turned to extracting gold from more difficult locations. Hydraulic mining was used on ancient gold-bearing gravel beds on hillsides and bluffs in the gold fields.:89 In hydraulic mining, a high-pressure hose directed a powerful stream or jet of water at gold-bearing gravel beds. By the mid-1880s, it is estimated that 11 million ounces (340 t) of gold (worth approximately US$15 billion at December 2010 prices) had been recovered by "hydraulicking". A byproduct of these extraction methods was that large amounts of gravel, silt, heavy metals, and other pollutants went into streams and rivers.:32–36 As of 1999[update], many areas still bear the scars of hydraulic mining, since the resulting exposed earth and downstream gravel deposits do not support plant life.:116-121
By 1855, it is estimated at least 300,000 gold-seekers, merchants, and other immigrants had arrived in California from around the world.:25 The huge numbers of newcomers brought by the Gold Rush drove Native Americans out of their traditional hunting, fishing and food-gathering areas. To protect their homes and livelihood, some Native Americans responded by attacking the miners. This provoked counter-attacks on native villages. The Native Americans, out-gunned, were often slaughtered.
The Gold Rush populated the western foothills of the Sierra Nevada, but even by 1860 most of the Sierra was unexplored. The state legislature authorized the California Geological Survey to officially explore the Sierra (and survey the rest of the state). Josiah Whitney was appointed to head the survey. Men of the survey, including William H. Brewer, Charles F. Hoffmann and Clarence King, explored the backcountry of what would become Yosemite National Park in 1863. In 1864 they explored the area around Kings Canyon. In 1869, John Muir started his wanderings in the Sierra Nevada range, and in 1871 King was the first to climb Mount Langley and that year fishermen were the first to climb Mount Whitney. From 1892–7 Theodore Solomons made the first attempt to map a route along the crest of the Sierra.
Other people finished exploring and mapping the Sierra. Bolton Coit Brown explored the Kings River watershed in 1895–1899. Joseph N. LeConte mapped the area around Yosemite National Park and what would become Kings Canyon National Park. James S. Hutchinson, a noted mountaineer, climbed the Palisades (1904) and Mount Humphreys (1905). By 1912, the USGS published a set of maps of the Sierra Nevada, and the era of exploration was over.:81
The tourism potential of the Sierra Nevada was recognized early in the European history of the range. Yosemite Valley was first protected by the federal government in 1864. The Valley and Mariposa Grove were ceded to California in 1866 and turned into a state park. John Muir perceived overgrazing by sheep and logging of Giant Sequoia to be a problem in the Sierra. Muir successfully lobbied for the protection of the rest of Yosemite National Park: Congress created an Act to protect the park in 1890. The Valley and Mariposa Grove were added to the Park in 1906. In the same year, Sequoia National Park was formed to protect the Giant Sequoia: all logging of the Sequoia ceased at that time.
In 1903, the city of San Francisco proposed building a hydroelectric dam to flood Hetch Hetchy Valley. The city and the Sierra Club argued over the dam for 10 years, until the U.S. Congress passed the Raker Act in 1913 and allowed dam building to proceed. O'Shaughnessy Dam was completed in 1923.
Between 1912 and 1918, Congress debated three times to protect Lake Tahoe in a national park. None of these efforts succeeded, and after World War II, towns such as South Lake Tahoe grew around the shores of the lake. By 1980, the permanent population of the Lake Tahoe area grew to 50,000, while the summer population grew to 90,000. The development around Lake Tahoe affected the clarity of the lake water. In order to preserve the lake's clarity, construction in the Tahoe basin is currently regulated by the Tahoe Regional Planning Agency.
As the 20th century progressed, more of the Sierra became available for recreation: other forms of economic activity decreased. The John Muir Trail, a trail that followed the Sierra crest from Yosemite Valley to Mount Whitney, was funded in 1915 and finished in 1938. Kings Canyon National Park was formed in 1940 to protect the deep canyon of the Kings River.
By 1964, the Wilderness Act protected portions of the Sierra as primitive areas where humans are simply temporary visitors. Gradually, 20 wilderness areas were established to protect scenic backcountry of the Sierra. These wilderness areas include the John Muir Wilderness (protecting the eastern slope of the Sierra and the area between Yosemite and Kings Canyon Parks), and wilderness within each of the National Parks.
