Nevada contains six biotic zones : alpine , sub-alpine , ponderosa pine , pinion-juniper , sagebrush and creosotebush . Nevada is divided into political jurisdictions designated as counties . Carson City

375-584: A county in 1856 by Utah Territorial Legislature and again in 1861 by the new Nevada Legislature. Clark County is the most populous county in Nevada, accounting for nearly three-quarters of its residents. Las Vegas, Nevada's most populous city, has been the county seat since the county was created in 1909 from a portion of Lincoln County, Nevada . Before that, it was a part of Arizona Territory. Clark County attracts numerous tourists: An estimated 44   million people visited Clark County in 2014. Washoe County

450-408: A population of 3,104,614 at the 2020 U.S. census . In 2022, the estimated population of Nevada was 3,177,772, an increase of 73,158 residents (2.36%) since the 2020 census . Nevada had the highest percentage growth in population from 2017 to 2018. At the 2020 census, 6.0% of the state's population were reported as under 5, 22.5% were under 18, and 16.1% were 65 or older. Females made up about 49.8% of

525-459: A potential state to have in order to become a state. At the time, Nevada's population was little more than 40,000. Governor Nye was frustrated that previous attempts to send the constitution via overland mail and by sea had failed by October 24, so on October 26 the full text was sent by telegraph at a cost of $ 4,303.27  – the most costly telegraph on file at the time for a single dispatch, equivalent to $ 83,831.36 in 2023. Finally,

600-721: A state boundary at just over 400 miles (640 km). This line begins in Lake Tahoe nearly 4 miles (6.4 km) offshore (in the direction of the boundary), and continues to the Colorado River where the Nevada, California, and Arizona boundaries merge 12 miles (19 km) southwest of the Laughlin Bridge. The largest mountain range in the southern portion of the state is the Spring Mountain Range , just west of Las Vegas. The state's lowest point

675-419: Is open central [ä] , whereas American English /ɑː/ varies from back [ɑː] to central [äː] ), it is not the pronunciation used by Nevadans. State Assemblyman Harry Mortenson proposed a bill to recognize the alternative pronunciation of Nevada, though the bill was not supported by most legislators and never received a vote. The Nevadan pronunciation is the one used by the state legislature. At one time,

750-623: Is almost entirely within the Basin and Range Province and is broken up by many north–south mountain ranges. Most of these ranges have endorheic valleys between them. Much of the northern part of the state is within the Great Basin , a mild desert that experiences hot temperatures in the summer and cold temperatures in the winter. Occasionally, moisture from the Arizona Monsoon will cause summer thunderstorms; Pacific storms may blanket

825-474: Is along the Colorado River, south of Laughlin. Nevada has 172 mountain summits with 2,000 feet (610 m) of prominence. Nevada ranks second, after Alaska, for the greatest number of mountains in the United States, followed by California, Montana, and Washington. Nevada is the driest state in the United States. It is made up of mostly desert and semi-arid climate regions, and, with the exception of

900-400: Is mainly because homesteads were not permitted in large enough sizes to be viable in the arid conditions that prevail throughout desert Nevada. Instead, early settlers would homestead land surrounding a water source, and then graze livestock on the adjacent public land, which is useless for agriculture without access to water (this pattern of ranching still prevails). The COVID-19 pandemic

975-442: Is officially a consolidated municipality, meaning it legally functions as both a city and a county. As of 1919, there were 17 counties in the state, ranging from 146 to 18,159 square miles (380 to 47,030 km ). Lake County , one of the original nine counties formed in 1861, was renamed Roop County in 1862. Part of the county became Lassen County, California , in 1864, resolving border uncertainty. In 1883, Washoe County annexed

1050-462: Is the fourth-largest producer of gold in the world. Nevada is the driest state, and has been influenced by climate change , droughts in Nevada have been increasing in frequency and severity, putting a further strain on Nevada's water security . The name "Nevada" comes from the Spanish adjective nevada ( [neˈβaða] ), meaning "snow-covered" or "snowy". The state takes its name from

1125-581: Is the largest city in the state. 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 campaigned during its relatively brief territorial status as the Nevada Territory (1861–1864), then quickly achieved statehood during the American Civil War (1861–1865), (the words "Battle Born" also appear on its state flag ); due to

1200-603: Is the remnant of prehistoric Lake Manly . The United States Geological Survey monitors the flow of the Amargosa River at a gauge station near the Old Spanish Trail Road, 0.2 miles (0.3 km) west of Tecopa. The average flow of the river at this station is 3.80 cubic feet per second (0.11 m/s). This is from a drainage area of 3,090 square miles (8,000 km), much of which is noncontributing and all of which represents about 60 percent of

1275-669: Is the second-most populous county of Nevada. Its county seat is Reno . Washoe County includes the Reno–Sparks metropolitan area . Lyon County is the third most populous county. It was one of the nine original counties created in 1861. It was named after Nathaniel Lyon , the first Union General to be killed in the Civil War . Its current county seat is Yerington . Its first county seat was established at Dayton on November 29, 1861. There are 68 designated wilderness areas in Nevada, protecting some 6,579,014 acres (2,662,433 ha) under

1350-644: Is under protection to conserve the diverse plant and animal species listed under the Endangered Species Act. Among these endangered species are the Amargosa vole, Least Bell's Vireo, and Southwestern Willow Flycatcher, recognized at both state and federal levels. Moreover, the state of California acknowledges the Yellow-Billed Cuckoo, Swainson's Hawk, and Amargosa Niterwort as species under threat. Additionally, two desert fish species,

1425-843: The Humboldt Sink near Lovelock . Several rivers drain from the Sierra Nevada eastward, including the Walker , Truckee , and Carson rivers. All of these rivers are endorheic basins , ending in Walker Lake , Pyramid Lake , and the Carson Sink , respectively. However, not all of Nevada is within the Great Basin. Tributaries of the Snake River drain the far north, while the Colorado River , which also forms much of

1500-491: The Las Vegas Valley , the average summer diurnal temperature range approaches 40 °F (22 °C) in much of the state. While winters in northern Nevada are long and fairly cold, the winter season in the southern part of the state tends to be of short duration and mild. Most parts of Nevada receive scarce precipitation during the year. The most rain that falls in the state falls on the east and northeast slopes of

1575-475: The Mexican–American War (1846–1848), and it was incorporated into the U.S. as part of the newly-organized larger federal New Mexico Territory (1850–1863 split with Arizona Territory , then statehood 1912) in the southern portion. To the north of the newly acquired Mexican / Spanish lands was the similarly larger Utah Territory (1850–1896) along with the far-western new 31st state of California on

1650-474: The Nevada Territory , which in turn was named for the Sierra Nevada . Nevadans pronounce the second syllable with the "a" of "apple" ( / n ə ˈ v æ d ə / ) while some people from outside of the state pronounce it with the "a" of "palm" ( / n ə ˈ v ɑː d ə / ). Although the quality , but not the length , of the latter pronunciation is closer to the Spanish pronunciation (Spanish /a/

1725-609: The Pacific Ocean coast also in 1850. The discovery of mineral wealth at the Comstock Lode silver bonanza in 1859 led to a population boom similar to that of earlier California Gold Rush in 1848–1852, that became an impetus to the creation of the Nevada Territory out of the western portion of the Utah Territory in 1861. Nevada became the 36th state on October 31, 1864, as the second of two states added to

1800-556: The Paiute , Shoshone , and Washoe tribes inhabited what is now Nevada. The first Europeans to explore the region were tho Spanish and explorers from their worldwide Spanish Empire in the 16th century . They called the region Nevada (snowy) because of the snow which covered the mountains in winter, similar to the Sierra Nevada mountains in European Spain . The area formed from mostly Alta California (Upper California) to

1875-448: The Sierra Nevada . The average annual rainfall per year is about 7 inches (180 mm); the wettest parts get around 40 inches (1,000 mm). Nevada's highest recorded temperature is 125 °F (52 °C) at Laughlin on June 29, 1994, and the lowest recorded temperature is −50 °F (−46 °C) at San Jacinto on January 8, 1937. Nevada's 125 °F (52 °C) reading is the third highest statewide record high temperature of

1950-680: The Sierra Nevadas and Mojave Desert and within the Las Vegas Valley. The enduring influence of New Mexico and Utah culture has since profoundly impacted Nevada's identity, manifesting through New Mexican cuisine and Mormon foodways or New Mexican and Mormon folk musics , into the fabric of Nevada's own cultural landscape. As a result of the Mexican–American War and the Treaty of Guadalupe Hidalgo , Mexico permanently lost Alta California in 1848. The new areas acquired by

2025-548: The habitat . Except during flash floods that occur after cloudbursts , most of the course of the Amargosa River is dry on the surface. The flow is generally underground except for stretches near Beatty and near Tecopa, California , in the Amargosa Canyon. In the canyon, the river passes through the Amargosa River Natural Area, a region of dense greenery and prolific wildlife made possible by

2100-405: The 16th presidency of Abraham Lincoln (1809–1865, served 1861–1865). The federal Union benefited immensely economically translated into military necessity from the support of newly awarded statehood as the 36th state by the massive infusion of the monetary support it provided of nearly $ 400 million dollars in rich underground geological layers of veins of silver ore generated at the time by

2175-457: The 1859 discovery of the legendary Comstock Lode , mined beneath and around Virginia City up to about 1874 / 1920s ). 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 the Spanish language , referring to Nevada's small overlap with the Sierra Nevada mountain range on its western edge; however,

2250-417: The 20th century. Nevada is the only U.S. state where prostitution is legal, though it is illegal in its most populated regions – Clark County (Las Vegas), Washoe County (Reno) and Carson City (which, as an independent city, is not within the boundaries of any county). The tourism industry remains Nevada's largest employer, with mining continuing as a substantial sector of the economy: Nevada

2325-522: The Amargosa Canyon. An interesting revelation concerns the genetic makeup of these fish, indicating an unexpected level of connectivity along the river. Particularly noteworthy is the genetic blend observed in the speckled dace population of the Amargosa Canyon, incorporating traits from both the Oasis Valley and Ash Meadows populations. This suggests that during significant flood events, speckled dace are capable of traversing considerable distances along

2400-523: The Amargosa Pupfish and Amargosa Speckled Dace, inhabit these regions and hold the designation of sensitive species according to the BLM. The Amargosa River Pupfish (Cyprinodon nevadensis amargosae) are one of the most notable residents of the Amargosa River. The species seems to be flourishing in the Amargosa Canyon, where its habitat has been safeguarded as a Wild and Scenic River, largely due to

2475-683: The Amargosa Range has remnants of indigenous habitations that are protected by the Bureau of Land Management . The Old Spanish Trail followed the course of the river in the Amargosa Canyon during the 19th century. From 1907 to 1941, the Tonopah and Tidewater Railroad followed the lower course of the river serving remote Death Valley communities. In March 2009, as part of the Eastern Sierra and Northern San Gabriel Wild Heritage Act,

2550-560: The Amargosa River area, supporting essential plants and animals. They also strive to maintain healthy populations of native fish, including Pupfish, Speckled dace, and Amargosa Toads. Moreover, they aim to enhance connections between various habitats, such as springs and upland areas, and restore natural conditions of springs and riverbanks to benefit native fish, amphibians, and snails. Collaborating with local public land management agencies, TNC plans sustainable land management strategies that prioritize nature long term. These efforts are vital for

2625-457: The Amargosa River, covering nearly 100 miles from Beatty to below Tecopa. These findings propose a level of interconnection among these populations not previously recognized in the pupfish. The Amargosa River is home to several crucial conservation areas, highlighting a diverse array of habitats like dunes, mesquite forests, springs, marshes, and riverbanks, all interconnected across the expansive watershed. Stretching nearly 3 million acres along

2700-496: The California-Nevada border, this region faces threats from urban development, recreation, and invasive species. The Nature Conservancy (TNC) is actively working to protect this ecosystem by preserving natural water flow, safeguarding native species like Amargosa Pupfish and Speckled Dace, as well as restoring critical habitats. The Nature Conservancy’s goal is to ensure the health of the natural water flow and processes in

2775-526: The Las Vegas area is situated, is within the Mojave Desert . The area receives less rain in the winter but is closer to the Arizona Monsoon in the summer. The terrain is also lower, mostly below 4,000 feet (1,200 m), creating conditions for hot summer days and cool to chilly winter nights. Nevada and California have by far the longest diagonal line (in respect to the cardinal directions) as

2850-558: The Narrows, still flowing roughly parallel to Route 95, the river passes Big Dune, which is on the river's left. Shortly after that, it passes the town of Amargosa Valley on the left, leaves Nevada, and enters Inyo County, California . In this stretch, it receives Forty Mile Wash from the left. Running roughly parallel to California Route 127 , the river passes through Death Valley Junction . Shortly after, it receives Carson Slough, which drains Ash Meadows National Wildlife Refuge , from

2925-631: The Nevada Territory separated from the Utah Territory and adopted its current name, shortened from The Sierra Nevada (Spanish for "snow-covered mountain range"). The 1861 southern boundary is commemorated by Nevada Historical Markers 57 and 58 in Lincoln and Nye counties. Eight days before the presidential election of 1864 , Nevada became the 36th state in the Union, despite lacking the minimum 60,000 residents that Congress typically required

3000-633: The Republicans won the election handily and did not need Nevada's help. Nevada is one of only two states to significantly expand its borders after admission to the Union, with the other being Missouri , which acquired additional territory in 1837 due to the Platte Purchase . In 1866 another part of the western Utah Territory was added to Nevada in the eastern part of the state, setting the current eastern boundary. Nevada achieved its current southern boundaries on January 18, 1867, when it absorbed

3075-478: The Union during the Civil War (the first being West Virginia ). Nevada is known for its libertarian laws. In 1940, with a population of just over 110,000 people, Nevada was by far the least-populated state, with less than half the population of the next least-populous state, Wyoming . However, legalized gambling and lenient marriage and divorce laws transformed Nevada into a major tourist destination in

3150-637: The United States continued to be administered as territories. As part of the Mexican Cession (1848) and the subsequent California Gold Rush that used Emigrant Trails through the area, the state's area evolved first as part of the Utah Territory and New Mexico Territory , then the Nevada Territory (March 2, 1861; named for the Sierra Nevada ). The first discovery of a major U.S. deposit of silver ore occurred in Comstock Lode under Virginia City, Nevada , in 1859. On March 2, 1861,

3225-525: The area with snow. The state's highest recorded temperature was 125 °F (52 °C) in Laughlin (elevation of 605 feet or 184 meters) on June 29, 1994. The coldest recorded temperature was −52  °F (−47  °C ) set in San Jacinto in 1972, in the northeastern portion of the state. The Humboldt River crosses the state from east to west across the northern part of the state, draining into

3300-413: The boundary with Arizona , drains much of southern Nevada. The mountain ranges, some of which have peaks above 13,000 feet (4,000 m), harbor lush forests high above desert plains, creating sky islands for endemic species. The valleys are often no lower in elevation than 3,000 feet (910 m), while some in central Nevada are above 6,000 feet (1,800 m). The southern third of the state, where

3375-642: The efforts of the Amargosa Conservancy. They primarily reproduce in loose groups, with males displaying minimal aggression and frequently engaging in courtship behavior towards females. However, a subset of males in this population stake out and protect specific breeding territories along the warm, shallow areas of the river. These territorial males exhibit aggression and only occasionally engage in courtship behaviors towards females The Amargosa River hosts three separate populations of Speckled Dace, situated in Oasis Valley near Beatty, Ash Meadows, and

3450-492: The federal government presented the $ 49   million construction contract for Boulder Dam (now Hoover Dam ). The Nevada Test Site , 65 miles (105 km) northwest of the city of Las Vegas, was founded on January 11, 1951, for the testing of nuclear weapons . The site consists of about 1,350 square miles (3,500 km ) of the desert and mountainous terrain. Nuclear testing at the Nevada Test Site began with

3525-419: The first permanent structure, a 150-foot square adobe fort , northeast of downtown Las Vegas, converging on the Spanish and Mormon Roads . The fort remained under Salt Lake City 's control until the winter of 1858–1859, and the route remained largely under the control of Salt Lake City and Santa Fe tradespersons. As such, these pioneers laid the foundation for the emergence of the initial settlements between

3600-421: The first phase of its reopening on May 9, 2020. Restaurants, retailers, outdoor malls, and hair salons were among the businesses allowed to reopen, but with precautions in place, such as limiting occupancy to 50 percent. A second phase went into effect on May 29, 2020. It allowed for the reopening of state parks and businesses such as bars, gyms, and movie theaters. Casinos began reopening on June 4, 2020. Nevada

3675-426: The ground aquifer . Except for a small portion of its route in the Amargosa Canyon in California and a small portion at Beatty, Nevada , the river flows above ground only after a rare rainstorm washes the region. A 26-mile (42 km) stretch of the river between Shoshone and Dumont Dunes is protected as a National Wild and Scenic River . At the south end of Tecopa Valley the Amargosa River Natural Area protects

Turning west, the river crosses under Route 127 and enters Death Valley National Park between the south end of the Amargosa Range on the right and the Avawatz Mountains on the left. Turning northwest and then north, the river re-enters Inyo County, passing between the Owlshead Mountains on the left and the Ibex Hills on the right and receives Confidence Wash and Rhodes Wash, both from

3975-550: The origin of the name Avawatz. It could be derived from the Mohave Indian term "Avi-Ahwat", or "red rock". Alternatively, the name comes from the Southern Paiute word iva-wätz , meaning "white mountain sheep," or another Southern Paiute word, ávawatz , meaning " gypsum ". The range lies to the west of State Route 127 ; between the Owlshead Mountains in the southern end of Death Valley National Park , and

4050-593: The period described in Roughing It , mining had led to an industry of speculation and immense wealth. Both mining and population temporarily declined in the late 19th century. However, the rich silver strike at Tonopah in 1900, followed by strikes in Goldfield and Rhyolite , created a second mining boom in Nevada and Nevada's population. Unregulated gambling was commonplace in the early Nevada mining towns but

4125-430: The population. 19.1% of the population was reported as foreign-born. Since the 2020 census, the population of Nevada had a natural increase of 2,374 (the net difference between 42,076 births and 39,702 deaths); and an increase due to net migration of 36,605 (of which 34,280 was due to domestic and 2,325 was due to international migration). The center of population of Nevada is in southern Nye County . In this county,

4200-591: The portion of Pah-Ute County in the Arizona Territory west of the Colorado River, essentially all of present-day Nevada south of the 37th parallel . The transfer was prompted by the discovery of gold in the area, and officials thought Nevada would be better able to oversee the expected population boom. This area includes most of what is now Clark County and the Las Vegas metropolitan area. Mining shaped Nevada's economy for many years (see Silver mining in Nevada ). When Mark Twain lived in Nevada during

Thirsty Canyon Wash enters at the river's source, and when carrying water, the river flows from there southwest into Oasis Valley. Running parallel to U.S. Route 95 near the Bullfrog Hills to the west ( right bank ),

4425-543: The province of Alta California became a territory (state) of Mexico, with a small population. Jedediah Smith entered the Las Vegas Valley in 1827, Peter Skene Ogden traveled the Humboldt River in 1828, and in 1829 a merchant from Nuevo México named Antonio Armijo streamlined travel along the Old Spanish Trail . Chronicling Armijo's route his scout Raphael Rivera was the first to name Las Vegas, in an 1830 report to governor José Antonio Chaves . Following

4500-480: The response from Washington came on October 31, 1864: "the pain is over, the child is born, Nevada this day was admitted into the Union". Statehood was rushed to the date of October 31 to help ensure Abraham Lincoln 's reelection on November   8 and post-Civil War Republican dominance in Congress, as Nevada's mining-based economy tied it to the more industrialized Union . As it turned out, however, Lincoln and
