Los Alamos, New Mexico

Census-designated place in New Mexico, United States From Wikipedia, the free encyclopedia

Los Alamos (Spanish: Los Álamos, meaning 'The Poplars') is a census-designated place in Los Alamos County, New Mexico, United States, that is recognized as one of the development and creation places of the atomic bomb—the primary objective of the Manhattan Project by Los Alamos National Laboratory during World War II. The town is on four mesas of the Pajarito Plateau, and had a population of about 13,200 as of 2020.[4] It is the county seat and one of two population centers in Los Alamos County; the other is White Rock.

Toponym

Los Alamos is a Spanish place name that typically refers to poplar or cottonwood trees. Alternatively, Los Alamos could refer to the large groves of quaking aspen that intersperse the coniferous forest on the mountainsides above the townsite, where they are distinctly visible in the autumn due to their spectacular autumn colors.[5][6][7]

History

The ruins of Puebloan settlements, such as those in nearby Bandelier National Monument and Tsankawi, and numerous other sites such as cliff dwellings indicate that the area has been inhabited during various eras since around 1150 AD. The first settlers on the plateau are thought to be Keres-speaking Native Americans around the 10th century. Around 1300, Tewa settlers immigrated from the Four Corners Region and built large cities but were driven out within 50 years by Navajo and Apache raids and by drought.

In the late 19th century, homesteaders used the land for ranching. About 1899, a road had been blasted up one of the canyons onto the Pajarito Plateau from Buckman (on the narrow-gauge Chili Line railroad) for the harvesting of timber, which in turn made the Plateau more accessible.[8] Homesteaders built simple log cabins that they lived in only during warm weather to feed livestock. Many of the homesteaders later moved down to the warmer Rio Grande Valley. In 1917, homesteader Harold H. Brook sold part of his land and buildings to Ashley Pond II, a businessman from Detroit who founded the Los Alamos Ranch School. The area was used to teach young men basic ranching and other outdoor survival skills.

In 1943, during World War II, the United States Department of War exercised eminent domain over the Ranch School and all remaining homesteads in the area so that the relatively isolated location could be used for the secretive Manhattan Project, which developed the first nuclear weapons.[9] Facilities for research and development were quickly built and scientists and engineers from all over the world were assigned to the project; all information about the town and project was held secret from the public. Los Alamos was referred to under the code name "Site Y" by military personnel and was known only as "The Hill" by many in nearby Santa Fe.

Los Alamos was originally built as a closed city accessible from the outside world only through two gates.[10] The project's location was a tightly guarded secret. All employees recruited to work at Los Alamos were given a memorandum instructing them to travel to Santa Fe and report to the U.S. Army Corps of Engineers office at 109 East Palace Avenue.[11] There, Dorothy McKibbin gave newcomers the necessary documentation to get through security checkpoints (initially, letters signed by J. Robert Oppenheimer, and later security passes), along with specific directions to the Hill.[12] The project was further concealed by using the mailing address PO Box 1663, Santa Fe, N.M.[13] All incoming truckloads were falsely labeled as common items to conceal the nature of their contents, and military officials censored outbound correspondence by those working and living in Los Alamos.

Not until after the bombing of Hiroshima in 1945 was information about the Manhattan Project released to the public, announced by the White House at 11 am on 6 August. A set of press releases were given out over three days.[14]

In the years after World War II, the laboratory was formally established as a research government facility under the civilian control of the U.S. Atomic Energy Commission, and is now known as Los Alamos National Laboratory. In 1957, the AEC pulled back the security perimeter to the laboratory and opened up the town to visits by the general public. The first visitor to enter the town that year without a permit from the federal government was New Mexico Governor Edwin L. Mechem.[15] The AEC was later succeeded by the U.S. Department of Energy.

Los Alamos served as the setting for much of the 2023 film Oppenheimer,[16] but mostly for interior scenes.[16] The town's appearance had changed drastically since the 1940s, so the filmmakers arranged for the construction of a set based on 1940s-era Los Alamos at Ghost Ranch and filmed exterior scenes there.[16]

Geography

Los Alamos is in northern New Mexico, between the Rio Grande and the eastern rim of the Valles Caldera on the Pajarito Plateau, about 35 mi (56 km) northwest of Santa Fe. The elevation at the post office is 7,320 feet (2,230 m) and total land area is 11.14 square miles (28.9 km2).

The Los Alamos Townsite and White Rock are on flat mesa tops known as potreros, separated by steep canyons. This location was chosen for its relative inaccessibility to help protect the Manhattan Project's secrecy.

The town of Los Alamos was built on four potreros—Barranca Mesa, North Mesa, Los Alamos Mesa, and South Mesa—along with the connecting communities at the base of the mountain. Los Alamos National Laboratory occupies half of South Mesa, Two Mile Mesa, Frijoles Mesa, Mesita de Buey, and several nearby areas in the region (in the valleys and at the base of the mountain). White Rock lies at the top of White Rock Canyon.

Much of Los Alamos County is within the Española Ranger District of the Santa Fe National Forest.

Wildlife and vegetation

Los Alamos's wildlife and vegetation are diverse compared to surrounding areas. "The variation in elevation creates precipitation and temperature gradients that support a wide diversity of plant communities".[21] There are six different plant communities in the county; each is home to unique flora and fauna.[21] Ponderosa pine trees are the most common trees at the elevation of Los Alamos (7,000 and 8,000 feet (2,100 and 2,400 m)). Common shrubs in the area include sagebrush, Gambel oak, and wild rose.[21]

Black bears (brown-color variation), elk, mule deer, bobcats, gray foxes, skunks and chipmunks are examples of mammals living in the area.[22] "Over 200 species of birds have been reported" in the Pajarito Ornithological Survey conducted by LANL.[23] Among these are broad-tailed hummingbirds, hairy woodpeckers, zone-tailed hawks, common ravens, western bluebirds, and great horned owls.[23]

Wildfires

Wildfires have affected the county, but the most destructive to the townsite was the Cerro Grande Fire of 2000, which caused an estimated $1 billion in damages and destroyed more than 400 homes. The CDP was evacuated for eight days. The Federal Emergency Management Agency (FEMA) built temporary housing on North Mesa for those who were displaced by the fire. Though there was no loss of life, other effects include damage to LANL facilities (nuclear material was not affected), flash-flooding, and erosion.

The Las Conchas Fire of 2011[24] burned about three times as many acres and also prompted evacuation of Los Alamos, but there was no damage to property in Los Alamos.[25] It was the largest recorded wildfire in New Mexico until the Whitewater-Baldy complex fire in 2012.[24][26]

Wildfires have altered plant communities in the area. Plant species are migrating to cover burn areas.

Environmental remediation

Over 2,000 sites in the area have been determined to have been affected by past activities at LANL. These sites have been identified throughout the county, and are primarily (but not exclusively) on DOE property. Contaminated sites vary widely in significance. Corrective action and environmental restoration has been deemed necessary for certain areas; LANL takes part in this process.[32] Some residents have voiced concern about a lack of public participation and opportunity to comment on the cleanup schedule and funding.[33]

Sports and recreation

Los Alamos's geography lends itself to several sports and recreational activities. There is an extensive system of trails in the canyons and into the mountains above the town, catering to all skill levels of running, hiking and mountain biking. The Aquatic Center is an indoor, Olympic-length public swimming pool with a therapy pool and lazy river. A public 18-hole golf course (par 72, 6500 yards) has existed since 1947.

Winter sports include skiing at the community-owned Pajarito Mountain Ski Area on 10,440 ft. Pajarito Mountain[50] between November and April. The county maintains New Mexico's only refrigerated, NHL regulation, outdoor ice skating rink on the sun-shaded floor of Los Alamos Canyon, almost beneath the Omega Bridge; the rink has existed since the Ranch School days. Snowshoeing and cross-country skiing are possible at Valles Caldera National Preserve and other locations, weather permitting.

Los Alamos hosts several sporting events:

  • Tour de Los Alamos (road cycling race)
  • Pajarito Punishment (mountain-biking race)
  • Los Alamos Triathlon (Los Alamos Junior Triathlon)
  • Jemez Mountain Trail Run

In 2015, the National Park Service and the U.S. Department of Energy announced the establishment of Manhattan Project National Historical Park in Los Alamos, along with units in Hanford, Washington and Oak Ridge, Tennessee.

Film

  • Director Christopher Nolan shot scenes from Oppenheimer in Los Alamos in March 2022,[51] filming at locations including the historic Fuller Lodge, Oppenheimer's house, Civilian's Women's Dormitory,[52] and United Church.[53] The production sought approximately 450 local background talent[54] for the film, including real local scientists.[55]
  • Ian Donnelly, a character played by Jeremy Renner in the 2016 film Arrival, is a theoretical physicist from Los Alamos.
  • Tiger Eyes is a 2012 film based on Judy Blume's 1981 young adult novel of the same name. This was the first major motion picture adaptation of any of Blume's books, which have sold more than 82 million copies in 41 countries.[56] Several outdoor scenes were shot in and around Los Alamos.
  • The 1988 comedy buddy film Twins begins in a genetics laboratory in Los Alamos, and revisits it later. It includes a few outdoor scenes in the city.
  • The Atomic City is a 1952 American film noir spy thriller film about H-bomb secrets that was the first feature film shot in Los Alamos, during the period that the community was still closed to the public at large. Scenes include the East Gate and its tower (some inside the building), and documentary footage of laboratory interiors, with workers’ faces redacted. Filming was also done at the nearby Puye Cliff Dwellings.[57]

Television

  • Manhattan, two series aired in 2014–15 about life in the city during Project Y. Not intended to be historically accurate but inspired by its history, with mostly fictional characters, though it does reference historical persons.

Education

Los Alamos Public Schools provides public Kindergarten through high school education (5 elementary schools, 1 middle school, and 1 high school: Los Alamos High School[58]). The graduation rate, as of 2021, is 93.3%, in comparison to New Mexico's 76.9% rate and America's average rate of 85%.[59]

The University of New Mexico has a branch campus in Los Alamos.

Economy

Los Alamos is the fifth-fastest-growing city in New Mexico, after Albuquerque, Rio Rancho, Las Cruces, and Ruidoso.[citation needed]

Income and poverty

The median household income in Los Alamos is $98,458, and per capita income is $54,067. Income is significantly higher than the rest of New Mexico.[35] Los Alamos has the highest millionaire concentration of any US city, with 12.4% of households having at least $1 million in assets.[60] This is a result of chemists, engineers, and physicists working at LANL since the Manhattan Project.[61] Only 6.6% of people are below the poverty line, one-third the rate of New Mexico.[35] As of 2015, there were no homeless people.[62]

Families and housing

There are 5,249 households and an average household size of 2.23 people. There are 5,863 housing units, and the median value of owner-occupied housing units is $281,500. Median gross rent is $921.[35]

31.4% of households have children under the age of 18 living with them, 56.4% are married couples living together, 6.5% have a female householder with no husband present, and 34.0% are non-families. 29.8% of all households are made up of individuals, and 7.6% have someone living alone who is 65 years of age or older.[citation needed]

Principal employers

Los Alamos National Laboratory is the area's largest employer with approximately 10,500 employees, and is foundational to Los Alamos's economy, with an annual budget of about $2.45 billion. About 40% of the laboratory's employees live in Los Alamos, while the remainder commute from Santa Fe, Española, Taos, and Albuquerque. About 66% of the people who work in the national laboratories commute daily to the lab; some take the Atomic City Transit, Rail Runner Express, use the Park and Ride, or carpool with other employees.[63]

Other major employers in Los Alamos include Los Alamos County, Los Alamos Public Schools, Los Alamos Medical Center, Smith's Food and Drug, Enterprise Bank & Trust, and Del Norte Credit Union.[64]

Transportation

Los Alamos provides several transportation services:[65][66]

Roads

Los Alamos is relatively isolated, and can only be accessed from NM 4 from the south and NM 502 from the east.

NM 502 sees significantly more traffic because it connects with US 84/285, which delivers access to several Pueblo communities between Española and Santa Fe. Approximately 10,000 commuters use NM 502 daily. NM 502 begins at Pojoaque, and traverses San Ildefonso Pueblo and the Rio Grande.

Interstate 25 is the nearest major interstate highway, and passes through or near Santa Fe, Albuquerque and Denver.

There are three access roads between White Rock and Los Alamos—Main Hill Road (NM 502), Jemez Road, and Pajarito Road. Since the September 11 attacks, Pajarito Road has been restricted to LANL badge holders for security reasons.

Transit systems

Air

Los Alamos County Airport, on the town's eastern edge, is the county's only airport. The main source of activity is from small private aircraft, with intermittent commercial commuter service.

Santa Fe Regional Airport is a 43-mile drive south of Los Alamos and serves regional flights to Dallas/Ft Worth, Houston, Denver, and Phoenix.

Albuquerque International Sunport is a 100-mile drive south of Los Alamos, and serves most national destinations.

Health care

The 47-bed acute-care facility known as Los Alamos Medical Center is Los Alamos's only hospital and is a LifePoint Health hospital. The hospital provides "complete medical, surgical, obstetrical, pediatric, emergency, and diagnostic services"[70] and employs about 300 Northern New Mexicans.[70]

Medical Associates of Northern New Mexico (MANNM) is a group of medical providers that offers family medicine, internal medicine, cardiology, nephrology, radiology, and endocrinology among its many services.[71]

During the Cold War, workers at LANL were in contact with radiation and other toxins, causing many of them illness. A nonprofit organization called Cold War Patriots provides these workers and their families with information about the healthcare benefits available to them.[72]
