United States Secretary of the Interior in the context of "Harold L. Ickes"

The National Natural Landmarks (NNL) Program in the United States recognizes and encourages the conservation of outstanding examples of the natural history of the country. It is the only national natural areas program that identifies and recognizes the best examples of biological and geological features in both public and private ownership. The program was established on May 18, 1962, by United States Secretary of the Interior Stewart Udall.

The program aims to encourage and support voluntary preservation of sites that illustrate the geological and ecological history of the United States. It also hopes to strengthen the public's appreciation of the country's natural heritage. As of July 2024, 605 sites have been added to the National Registry of Natural Landmarks. The registry includes nationally significant geological and ecological features in 48 states, American Samoa, Guam, Puerto Rico, and the U.S. Virgin Islands.

Yellowstone National Park is a national park of the United States located in the northwest corner of the state of Wyoming, with small portions extending into Montana and Idaho. It was established by the 42nd U.S. Congress through the Yellowstone National Park Protection Act and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the US, and is also widely understood to be the first national park in the world. The park is known for its wildlife and its many geothermal features, especially the Old Faithful geyser, one of its most popular. While it represents many types of biomes, subalpine forest is the most abundant. It is part of the South Central Rockies forests ecoregion.

While Native Americans have lived in the Yellowstone region for at least 11,000 years, aside from visits by mountain men during the early-to-mid-19th century, organized exploration did not begin until the late 1860s. Management and control of the park originally fell under the jurisdiction of the U.S. Department of the Interior, the first secretary of the interior to supervise the park being Columbus Delano. However, the U.S. Army was eventually commissioned to oversee the management of Yellowstone for 30 years between 1886 and 1916. In 1917, the administration of the park was transferred to the National Park Service, which had been created the previous year. Hundreds of structures have been built and are protected for their architectural and historical significance, and researchers have examined more than one thousand indigenous archaeological sites.

The United States Board on Geographic Names (BGN) is a federal body operating under the United States secretary of the interior. The purpose of the board is to establish and maintain uniform usage of geographic names throughout the federal government of the United States.

The Public Works Administration (PWA), part of the New Deal of 1933, was a large-scale public works construction agency in the United States headed by Secretary of the Interior Harold L. Ickes. It was created by the National Industrial Recovery Act in June 1933 in response to the Great Depression. It built large-scale public works such as dams, bridges, hospitals, and schools. Its goals were to spend $3.3 billion in the first year, and $6 billion in all, to supply employment, stabilize buying power, and help revive the economy. Most of the spending came in two waves, one in 1933–1935 and another in 1938. Originally called the Federal Emergency Administration of Public Works, it was renamed the Public Works Administration in 1935 and shut down in 1944.

The PWA spent over $7 billion on contracts with private construction firms that did the actual work. It created an infrastructure that generated national and local pride in the 1930s and is still vital nine decades later. The PWA was much less controversial than its rival agency, the Works Progress Administration (WPA), headed by Harry Hopkins, which focused on smaller projects and hired unemployed unskilled workers.

The United States Department of the Interior (DOI) is an executive department of the U.S. federal government responsible for the management and conservation of most federal lands and natural resources. It also administers programs relating to Native Americans, Alaska Natives, Native Hawaiians, and four of the five inhabited insular areas of the United States, as well as programs related to historic preservation. About 75% of federal public land is managed by the department, with most of the remainder managed by the Department of Agriculture's Forest Service. The department was created on March 3, 1849. It is headquartered at the Main Interior Building, located at 1849 C Street NW in Washington, D.C.

The department is headed by the secretary of the interior, who reports directly to the president of the United States and is a member of the president's Cabinet. The current interior secretary is Doug Burgum, who was sworn in on February 1, 2025.

The Bureau of Indian Affairs (BIA), also known as Indian Affairs (IA), is a United States federal agency within the Department of the Interior. It is responsible for implementing federal laws and policies related to Native Americans and Alaska Natives, and administering and managing over 55,700,000 acres (225,000 km) of reservations held in trust by the U.S. federal government for indigenous tribes. It renders services to roughly 2 million indigenous Americans across 574 federally recognized tribes. The BIA is governed by a director and overseen by the assistant secretary for Indian affairs, who answers to the secretary of the interior.

The BIA works with tribal governments to help administer law enforcement and justice; promote development in agriculture, infrastructure, and the economy; enhance tribal governance; manage natural resources; and generally advance the quality of life in tribal communities. Educational services are provided by Bureau of Indian Education—the only other agency under the Assistant Secretary for Indian affairs—while health care is the responsibility of the U.S. Department of Health and Human Services through its Indian Health Service.

Stewart Lee Udall (January 31, 1920 – March 20, 2010) was an American politician and environmentalist who belonged to the Democratic Party. After serving three terms as a congressman from Arizona, he served as Secretary of the Interior from 1961 to 1969, under presidents John F. Kennedy and Lyndon B. Johnson. A staunch liberal, he is best known for enthusiastically promoting environmentalism while in the cabinet, with success primarily under President Johnson.

Columbus Delano (June 4, 1809 – October 23, 1896) was an American lawyer, rancher, banker, statesman, and a member of the prominent Delano family. Forced to live on his own at an early age, Delano struggled to become a self-made man. Delano was elected U.S. Congressman from Ohio, serving two full terms and one partial one. Prior to the American Civil War, Delano was a National Republican and then a Whig; as a Whig, he was identified with the faction of the party that opposed the spread of slavery into the Western territories. He became a Republican when the party was founded as the major anti-slavery party after the demise of the Whigs in the 1850s. During Reconstruction Delano advocated federal protection of African-Americans' civil rights, and argued that the former Confederate states should be administered by the federal government, but not as part of the United States until they met the requirements for readmission to the Union.

Delano served as President Ulysses S. Grant's Secretary of the Interior during a time of rapid Westward expansionism, and contended with conflicts between Native tribes and White American settlers. He was instrumental in the establishment of America's first national park, having supervised the first federally funded scientific expedition into Yellowstone in 1871, and becoming America's first national park overseer in 1872. In 1874, Delano requested that Congress protect Yellowstone through the creation of a federally funded administrative agency, the first Secretary of the Interior to request such preservation of a nationally important site.
