10508-590: The above, including possible glacial till from the hypothesized Snowball Earth glaciation. The very youngest rocks in the Pahrump Group are basaltic lava flows. A rift opened and subsequently flooded the region as part of the breakup of the supercontinent Rodinia in the Neoproterozoic (by about 755 million years ago) and the creation of the Pacific Ocean . A shoreline similar to
10650-484: The area from as early as 7000 BC, most recently the Timbisha around 1000 AD who migrated between winter camps in the valleys and summer grounds in the mountains. A group of European-Americans, lost in the valley in 1849 while looking for a shortcut to the gold fields of California , gave this valley its grim name, even though only one of their group died there. Several short-lived boom towns sprang up during
10792-707: The area from the Colorado River via a long-since dried-up system of rivers and lakes (see Lake Manly ). They now live in two separate populations: one in Salt Creek and another in Cottonball Marsh. Death Valley is one of the hottest and driest places in North America, yet it is home to over 1,000 species of plants ; 23 of which, including the very rare rock lady ( Holmgrenanthe ), are not found anywhere else. List of national parks of
10934-401: The area that comprises the park has experienced at least four major periods of extensive volcanism , three or four periods of major sedimentation , and several intervals of major tectonic deformation where the crust has been reshaped. Two periods of glaciation (a series of ice ages) have also had effects on the area, although no glaciers ever existed in the ranges now in the park. Little
11076-711: The area were also the easiest to collect and the most profitable: evaporite deposits such as salts, borate , and talc . Borax was found by Rosie and Aaron Winters near The Ranch at Death Valley (then called Greenland) in 1881. Later that same year, the Eagle Borax Works became Death Valley's first commercial borax operation. William Tell Coleman built the Harmony Borax Works plant and began to process ore in late 1883 or early 1884, continuing until 1888. This mining and smelting company produced borax to make soap and for industrial uses. The end product
11218-473: The area, except for some possibly Jurassic-age volcanic rocks (see the top of the timescale image ). Basin and Range -associated stretching of large parts of crust below southwestern United States and northwestern Mexico started around 16 million years ago and the region is still spreading. This stretching began to affect the Death and Panamint valleys area by 3 million years ago. Before this, rocks now in
11360-675: The commissioner's power to vote in the Committee of the Whole , but the commissioner can vote in committee. Puerto Rican elections are governed by the Federal Election Commission and the State Elections Commission of Puerto Rico . Residents of Puerto Rico, including other U.S. citizens, cannot vote in U.S. presidential elections, but can vote in primaries . Puerto Ricans who become residents of
11502-521: The dry and wet seasons, there is a temperature change of around 6 °F (3.3 °C). This change is due mainly to the warm waters of the tropical Atlantic Ocean , which significantly modify cooler air moving in from the north and northwest. Coastal water temperatures during the year are about 75 °F (24 °C) in February and 85 °F (29 °C) in August. The highest temperature ever recorded
11644-501: The early-to-mid- Mesozoic the western edge of the North American continent was pushed against the oceanic plate under the Pacific Ocean, creating a subduction zone. A subduction zone is a type of contact between different crustal plates where heavier crust slides below lighter crust. Erupting volcanoes and uplifting mountains were created as a result, and the coastline was pushed to the west. The Sierran Arc started to form to
11786-399: The federal government, Puerto Rico-based corporations that intend to send funds to the U.S., and some others, such as Puerto Rican residents that are members of the U.S. military, and Puerto Rico residents who earned income from sources outside Puerto Rico also pay federal income taxes. In addition, because the cutoff point for income taxation is lower than that of the U.S. IRS code, and because
11928-552: The figures below. The 431 units of the National Park System can be broadly referred to as national parks, but most have other formal designations. A bill creating the first national park, Yellowstone , was signed into law by President Ulysses S. Grant in 1872, followed by Mackinac National Park in 1875 (decommissioned in 1895), and then Rock Creek Park (later merged into National Capital Parks ), Sequoia and Yosemite in 1890. The Organic Act of 1916 created
12070-437: The general trend of Basin and Range topography with one modification: there are parallel strike-slip faults that perpendicularly bound the central extent of Death Valley. The result of this shearing action is additional extension in the central part of Death Valley which causes a slight widening and more subsidence there. Uplift of surrounding mountain ranges and subsidence of the valley floor are both occurring. The uplift on
12212-415: The government to move rapidly to provide for the general welfare contributed to political activism by opponents and eventually to the rise of the Puerto Rican Nationalist Party . On 7 January 2020, the country experienced its largest earthquake since 1918, estimated at magnitude 6.4. Economic losses were estimated to be more than $ 3.1 billion. The Puerto Rico Trench , the largest and deepest trench in
12354-479: The higher mountains that surround the valley. When rain does arrive it often does so in intense storms that cause flash floods which remodel the landscape and sometimes create very shallow ephemeral lakes. The hot, dry climate makes it difficult for soil to form. Mass wasting , the down-slope movement of loose rock, is therefore the dominant erosive force in mountainous areas, resulting in "skeletonized" ranges (mountains with very little soil on them). Sand dunes in
12496-514: The island. It is also home to 50 bird species, including the critically endangered Puerto Rican amazon . In addition to El Yunque National Forest, the Puerto Rican moist forest ecoregion is represented by protected areas such as the Maricao and Toro Negro state forests . These areas are home to endangered endemic species such as the Puerto Rican boa ( Chilabothrus inornatus ), the Puerto Rican sharp-shinned hawk ( Accipiter striatus venator ),
12638-518: The islands on the condition that they swear their loyalty to the Spanish Crown and allegiance to the Catholic Church . In 1898, during the Spanish–American War , Puerto Rico was invaded and subsequently became a possession of the U.S. The first years of the 20th century were marked by the struggle to obtain greater democratic rights from the U.S. The Foraker Act of 1900 established a civil government, ending rule by American generals and
12780-460: The larger Death Valley springs derive their water from a regional aquifer , which extends as far east as southern Nevada and Utah . Much of the water in this aquifer has been there for many thousands of years, since the Pleistocene ice ages , when the climate was cooler and wetter. Today's drier climate does not provide enough precipitation to recharge the aquifer at the rate at which water
12922-597: The last election held in November 2020 . The judicial branch is headed by the chief justice of the Supreme Court of Puerto Rico , currently Maite Oronoz Rodríguez . Members of the judiciary are appointed by the governor with the advice and consent of the Senate. Puerto Rico is represented in the U.S. Congress by a nonvoting delegate to the House of Representatives, the resident commissioner , currently Jenniffer González . Current congressional rules have removed
13064-414: The late 19th and early 20th centuries to mine gold and silver. The only long-term profitable ore to be mined was borax , which was transported out of the valley with twenty-mule teams . The valley later became the subject of books, radio programs, television series, and movies. Tourism expanded in the 1920s when resorts were built around Stovepipe Wells and Furnace Creek . Death Valley National Monument
13206-561: The late 19th century, a distinct Puerto Rican identity began to emerge, centered around a fusion of European , African , and indigenous elements. In 1898, following the Spanish–American War , Puerto Rico was acquired by the United States . Puerto Ricans have been U.S. citizens since 1917 and can move freely between the archipelago and the mainland . However, residents of Puerto Rico are disenfranchised from federal elections and generally do not pay federal income tax . In common with four other territories , Puerto Rico sends
13348-488: The latter four dune fields are accessible only via unpaved roads. Prevailing winds in the winter come from the north, and prevailing winds in the summer come from the south. Thus, the overall position of the dune fields remains more or less fixed. There are rare exceptions to the dry nature of the area. In 2005, an unusually wet winter created a 'lake' in the Badwater Basin and led to the greatest wildflower season in
13490-505: The local Chamber of Commerce estimates that 6,000 people are moving to the city every month. Between 1985 and 1995, the population of the Las Vegas Valley increased from 550,700 to 1,138,800. In 1977, parts of Death Valley were used by director George Lucas as a filming location for Star Wars , providing the setting for the fictional planet Tatooine . The park has a diverse and complex geologic history. Since its formation,
13632-588: The most dangerous geologic hazards in the island and in the northeastern Caribbean. The 1918 San Fermín earthquake occurred on 11 October , 1918 and had an estimated magnitude of 7.5 on the Richter scale . It originated off the coast of Aguadilla , several kilometers off the northern coast, and was accompanied by a tsunami . It caused extensive property damage and widespread losses, damaging infrastructure, especially bridges. It resulted in an estimated 116 deaths and $ 4 million in property damage. The failure of
13774-666: The most-visited park since 1944, and had almost 13 million visitors in 2022. In contrast, only about 9,500 people visited the remote Gates of the Arctic National Park and Preserve in Alaska in 2022. Download coordinates as: The following table includes the 30 states and two territories that have national parks. Exclusive parks refer to parks entirely within one state or territory. Shared parks refer to parks in multiple states. Territories are set in italics . Puerto Rico Puerto Rico ( Spanish for 'rich port'; abbreviated PR ), officially
13916-400: The mountain ridges where they harvested pine nuts before moving back to the valley bottom for winter. The California Gold Rush brought the first people of European descent known to visit the immediate area. In December 1849 two groups of California Gold Country -bound travelers with perhaps 100 wagons total stumbled into Death Valley after getting lost on what they thought was a shortcut off
14058-528: The national monument. The public outcry that ensued led to greater protection for all national park and monument areas in the United States. In 1976, Congress passed the Mining in the Parks Act, which closed Death Valley National Monument to the filing of new mining claims, banned open-pit mining and required the National Park Service to examine the validity of tens of thousands of pre-1976 mining claims. Mining
14200-472: The newest national park is New River Gorge , previously a National River, and the most recent entirely new park is National Park of American Samoa . A few former national parks are no longer designated as such , or have been disbanded. Fourteen national parks are designated UNESCO World Heritage Sites (WHS), and 21 national parks are named UNESCO Biosphere Reserves (BR), with eight national parks in both programs. Thirty states have national parks, as do
14342-555: The next 400 years. The decline of the indigenous population , followed by an influx of Spanish settlers, primarily from the Canary Islands and Andalusia , and African slaves vastly changed the cultural and demographic landscape of the archipelago. Within the Spanish Empire , Puerto Rico played a secondary but strategically significant role compared to larger and wealthier colonies like Peru and New Spain . By
14484-606: The northwest corner of the Mojave Desert and its diverse environment of salt-flats , sand dunes , badlands , valleys, canyons and mountains. Death Valley is the largest national park in the contiguous United States , as well as the hottest, driest and lowest of all the national parks in the United States. It contains Badwater Basin , the second-lowest point in the Western Hemisphere and lowest in North America at 282 feet (86 m) below sea level. More than 93% of
14626-442: The northwest from heat and pressure generated from subduction, and compressive forces caused thrust faults to develop. A long period of uplift and erosion was concurrent with and followed the above events, creating a major unconformity, which is a large gap in the geologic record. Sediments worn off the Death Valley region were carried both east and west by wind and water. No Jurassic- to Eocene -aged sedimentary formations exist in
14768-579: The other was a one-eyed Basque butcher named Domingo Etcharren. Quite by accident, Keane discovered an immense ledge of free-milling gold by the duo's work site and named the claim the Keane Wonder Mine . This started a minor and short-lived gold rush into the area. The Keane Wonder Mine, along with mines at Rhyolite , Skidoo and Harrisburg , were the only ones to extract enough metal ore to make them worthwhile. Outright shams such as Leadfield also occurred, but most ventures quickly ended after
14910-469: The park is a designated wilderness area . The park is home to many species of plants and animals which have adapted to the harsh desert environment including creosote bush , Joshua tree , bighorn sheep , coyote , and the endangered Death Valley pupfish , a survivor from much wetter times. UNESCO included Death Valley as the principal feature of its Mojave and Colorado Deserts Biosphere Reserve in 1984. A series of Native American groups inhabited
15052-481: The park is the Racetrack , known for its moving rocks. According to the Köppen climate classification system, Death Valley National Park has a hot desert climate ( BWh ). The plant hardiness zone at Badwater Basin is 9b with an average annual extreme minimum temperature of 28.0 °F (−2.2 °C). Death Valley is the hottest and driest place in North America due to its lack of surface water and low relief. It
15194-503: The park's history. In October 2015, a "1000 year flood event" with over three inches of rain caused major damage in Death Valley National Park. A similar widespread storm in August 2022 damaged pavement and deposited debris on nearly every road, trapping 1,000 residents and visitors overnight. Four Native American cultures are known to have lived in the area during the last 10,000 years. The first known group,
15336-669: The park, and some of the highest in North America, are located in the Eureka Valley about 50 miles (80 km) to the north of Stovepipe Wells, while the Panamint Valley dunes and the Saline Valley dunes are located west and northwest of the town, respectively. The Ibex dune field is near the seldom-visited Ibex Hill in the southernmost part of the park, just south of the Saratoga Springs marshland. All
15478-430: The park, while famous, are not nearly as widespread as their fame or the dryness of the area may suggest. The Mesquite Flat dune field is the most easily accessible from the paved road just east of Stovepipe Wells in the north-central part of the valley and is primarily made of quartz sand. Another dune field is just 10 miles (16 km) to the north but is instead mostly composed of travertine sand. The highest dunes in
15620-400: The park. Many of the larger cities and towns within the boundary of the regional groundwater flow system that the park and its plants and animals rely upon are experiencing some of the fastest growth rates of any place in the United States. Notable examples within a 100-mile (160 km) radius of Death Valley National Park include Las Vegas and Pahrump, Nevada . In the case of Las Vegas,
15762-445: The parties' presidential candidates. Since Puerto Rico is an unincorporated territory and not a U.S. state, the U.S. Constitution does not fully enfranchise U.S. citizens residing in Puerto Rico. Only fundamental rights under the American federal constitution and adjudications are applied to Puerto Ricans. Various other U.S. Supreme Court decisions have held which rights apply in Puerto Rico and which ones do not. Puerto Ricans have
15904-476: The per-capita income in Puerto Rico is much lower than the average per-capita income on the mainland, more Puerto Rico residents pay income taxes to the local taxation authority than if the IRS code were applied to the island. This occurs because "the Commonwealth of Puerto Rico government has a wider set of responsibilities than do U.S. State and local governments." In 2009, Puerto Rico paid $ 3.742 billion into
16046-570: The pinyon/juniper associations of the Grapevine, Cottonwood, and Panamint ranges. Bighorn sheep are a rare species of mountain-dwelling sheep that exist in isolated bands in the Sierra and in Death Valley. These are highly adaptable animals and can eat almost any plant. They have no known predators, but humans and burros compete for habitat. The ancestors of the Death Valley pupfish swam to
16188-507: The population applying for assistance after the storms. See also Effects of Hurricane Maria in Puerto Rico It is thought that a combination of the debt crisis and two major hurricanes in the late 2010s, caused further departures from the island. Overall the population has decreased by about half a million in the 21st century, with many seeking better opportunities on the mainland. Puerto Rico held its statehood referendum during
16330-533: The present Atlantic Ocean margin of the United States lay to the east. An algal mat -covered carbonate bank was deposited, forming the Noonday Dolomite. Subsidence of the region occurred as the continental crust thinned and the newly formed Pacific widened, forming the Ibex Formation. An angular unconformity (an uneven gap in the geologic record) followed. A true ocean basin developed to
16472-565: The region, meaning the water there was saturated in dissolved materials. Thus, the salt pans in Death Valley are among the largest in the world and are rich in minerals, such as borax and various salts and hydrates . The largest salt pan in the park extends 40 miles (64 km) from the Ashford Mill Site to the Salt Creek Hills, covering some 200 square miles (520 km) of the valley floor. The best known playa in
16614-505: The retention of more or less the same valley floor elevation over time. Pleistocene ice ages started 2 million years ago, and melt from alpine glaciers on the nearby Sierra Nevada Mountains fed a series of lakes that filled Death and Panamint valleys and surrounding basins (see the top of the timescale image ). The lake that filled Death Valley was the last of a chain of lakes fed by the Amargosa and Mojave Rivers , and possibly also
16756-418: The second question to be voted on in November. The second question posed three alternate status options: statehood, independence, or free association . 61.16% voted for statehood, 33.34% for a sovereign free-associated state, and 5.49% for independence. In 2016, President Barack Obama signed into law H.R. 5278: PROMESA , establishing a Control Board over the Puerto Rican government. This board will have
16898-670: The seven year-long bioluminescent bays in the Caribbean: Laguna Grande in Fajardo , La Parguera in Lajas and Puerto Mosquito in Vieques . These are unique bodies of water surrounded by mangroves that are inhabited by the dinoflagellate Pyrodinium bahamense . However, tourism, pollution, and hurricanes have highly threatened these unique ecosystems. Puerto Rico has a republican form of government based on
17040-706: The size of Hispaniola and 8% of the size of Cuba, the largest of the Greater Antilles. The topography of the island is mostly mountainous with large flat areas in the northern and southern coasts. The main mountain range that crosses the island from east to west is called the Cordillera Central (also known as the Central Mountain Range in English). The highest elevation in Puerto Rico, Cerro de Punta 4,390 feet (1,340 m),
17182-465: The south, since the south receives less rain than the central and northern regions. Puerto Rico is composed of Cretaceous to Eocene volcanic and plutonic rocks, overlain by younger Oligocene and more recent carbonates and other sedimentary rocks . Most of the caverns and karst topography on the island occurs in the northern region. The oldest rocks are approximately 190 million years old ( Jurassic ) and are located at Sierra Bermeja in
17324-478: The southwest part of the island. They may represent part of the oceanic crust and are believed to come from the Pacific Ocean realm. Puerto Rico lies at the boundary between the Caribbean and North American Plates and is being deformed by the tectonic stresses caused by their interaction. These stresses may cause earthquakes and tsunamis . These seismic events, along with landslides , represent some of
17466-614: The southwest, the Guánica State Forest and Biosphere Reserve contain over 600 uncommon species of plants and animals, including 48 endangered species and 16 that are endemic to Puerto Rico, and is considered a prime example of the Puerto Rican dry forest ecoregion and the best-preserved dry forest in the Caribbean. Other protected dry forests in Puerto Rico can be formed within the Caribbean Islands National Wildlife Refuge complex at
17608-432: The summit of Telescope Peak, which rises to 11,049 feet (3,368 m). Vegetation zones include creosote bush , desert holly , and mesquite at the lower elevations and sage up through shadscale , blackbrush , Joshua tree , pinyon - juniper , to limber pine and bristlecone pine woodlands. The salt pan is devoid of vegetation, and the rest of the valley floor and lower slopes have sparse cover, although where water
17750-521: The surface of the Earth. (A report of a temperature of 58 °C (136 °F) recorded in Libya in 1922 was later determined to be inaccurate.) Daily summer temperatures of 120 °F (49 °C) or greater are common, as well as below freezing nightly temperatures in the winter. July is the hottest month, with an average high of 117 °F (47 °C) and an average low of 91 °F (33 °C). December
17892-488: The valley was a popular winter destination. Other facilities started off as private getaways but were later opened to the public. Most notable among these was Death Valley Ranch, better known as Scotty's Castle . This large ranch home built in the Spanish Revival style became a hotel in the late 1930s and, largely because of the fame of Death Valley Scotty , a tourist attraction. Death Valley Scotty, whose real name
18034-420: The valley. Just after leaving the valley, one of the women in the group turned and said, "Goodbye Death Valley," giving the valley its name. Included in the party was William Lewis Manly whose autobiographical book Death Valley in '49 detailed this trek and popularized the area (geologists later named the prehistoric lake that once filled the valley after him). The ores that are most famously associated with
18176-593: The wagon's image to promote the Boraxo brand of granular hand soap and the Death Valley Days radio and television programs. In 1914, the Death Valley Railroad was built to serve mining operations on the east side of the valley. Mining continued after the collapse of Coleman's empire, and by the late 1920s the area was the world's number one source of borax. Some four to six million years old,
18318-618: The way for the drafting of Puerto Rico's Constitution and its approval by Congress and Puerto Rican voters in 1952. Puerto Rico is one of five territories with less representation in the Federal government, along with the Federal District. In 2009, the United Nations Special Committee on Decolonization approved a draft resolution calling on the U.S. government to expedite a process that would allow
18460-409: The west, breaking all the earlier formations along a steep front. A wedge of clastic sediment then began to accumulate at the base of the two underwater precipices, starting the formation of opposing continental shelves . Three formations developed from sediment that accumulated on the wedge. The region's first known fossils of complex life are found in the resulting formations. Notable among these are
18602-467: The wide altitude differential between the valley bottom and the mountain ridges, especially on the west, the Timbisha practiced a vertical migration pattern. Their winter camps were located near water sources in the valley bottoms. As the spring and summer progressed and the weather warmed, grasses and other plant food sources ripened at progressively higher altitudes. November found them at the very top of
18744-465: Was 110 °F (43 °C) at Arecibo , while the lowest temperature ever recorded was 40 °F (4 °C) in the mountains at Adjuntas , Aibonito , and Corozal . The average yearly precipitation is 66 in (1,676 mm). Climate change in Puerto Rico has had a large impact on the ecosystems and landscapes. Puerto Rico experiences the Atlantic hurricane season , similar to the rest of
18886-419: Was Walter Scott, was a gold miner who pretended to be the owner of "his castle", which he claimed to have built with profits from his gold mine. Neither claim was true, but the real owner, Chicago millionaire Albert Mussey Johnson , encouraged the myth. When asked by reporters what his connection was to Walter Scott's castle, Johnson replied that he was Mr. Scott's banker. President Herbert Hoover proclaimed
19028-460: Was allowed to resume on a limited basis in 1980 with stricter environmental standards. The last mine in the park, Billie Mine, closed in 2005. In 1952 President Harry Truman added the Devils Hole to Death Valley National Monument; it is the only habitat of the Devils Hole pupfish . Death Valley National Monument was designated a biosphere reserve in 1984. On October 31, 1994, the monument
19170-601: Was boycotted by some political opponents of it. (see 2017 Puerto Rican status referendum ) In 2017, Puerto Rico suffered back-to-back large hurricanes: the Category 5 Hurricane Irma (September 7, 2017) and the Category 4 Hurricane Maria (September 20, 2017). The storms caused an extreme amount of damage to the island, causing the following effects: all power was knocked out, 95% cell service, 43% of waste water treatment plants, 40 thousand land slides, 97% of roads blocked, 28% of health facilities damaged, leading to over 90% of
19312-446: Was declared in 1933 and the park was substantially expanded and became a national park in 1994. The natural environment of the area has been shaped largely by its geology. The valley is actually a graben with the oldest rocks being extensively metamorphosed and at least 1.7 billion years old. Ancient, warm, shallow seas deposited marine sediments until rifting opened the Pacific Ocean . Additional sedimentation occurred until
19454-588: Was expanded by 1.3 million acres (5,300 km) and re-designated as a national park , via congressional passage of the California Desert Protection Act (Public Law 103–433). Consequently, the elevated status for Death Valley made it the largest national park in the contiguous United States . On March 12, 2019, the John D. Dingell, Jr. Conservation, Management, and Recreation Act added 35,292 acres (55 sq mi; 143 km) to
19596-536: Was quickly reopened to mining by Congressional action in June 1933. As improvements in mining technology allowed lower grades of ore to be processed, and new heavy equipment allowed greater amounts of rock to be moved, mining in Death Valley changed. Gone were the days of the "single-blanket, jackass prospector" long associated with the romantic west. Open pit and strip mines scarred the landscape as international mining corporations bought claims in highly visible areas of
19738-405: Was settled by a succession of Amerindian peoples beginning 2,000 to 4,000 years ago; these included the Ortoiroid , Saladoid , and Taíno . It was claimed by Spain following the arrival of Christopher Columbus in 1493 and subsequently colonized by Juan Ponce de León in 1508. Puerto Rico was contested by other European powers into the 18th century but remained a Spanish possession for
19880-562: Was shipped out of the valley 165 miles (266 km) to the Mojave railhead in 10-ton-capacity wagons pulled by " twenty-mule teams " that were actually teams of 18 mules and two horses each. The teams averaged two miles (3.2 km) an hour and required about 30 days to complete a round trip. The trade name 20-Mule Team Borax was established by Francis Marion Smith 's Pacific Coast Borax Company after Smith acquired Coleman's borax holdings in 1890. A memorable advertising campaign used
20022-457: Was suggested by its architect Luis Muñoz Marín and adopted by a constitutional assembly on July 25 1952. Some authorities have called it a euphemism and have charged that the official name in English of "Commonwealth" constitutes a fig leaf , i.e., associated with the covering up of an act that is actually embarrassing or distasteful with something of innocuous appearance. Puerto Rico remains
20164-570: Was used by the U.S. government and private enterprises (also Porto in Italian, French, and Portuguese). The name was changed back to Puerto Rico in 1931 by a joint resolution in Congress introduced by Félix Córdova Dávila . The official name of the entity in Spanish is Estado Libre Asociado de Puerto Rico ("Free Associated State of Puerto Rico"), while its official English name is Commonwealth of Puerto Rico . The Spanish official name
