Lovelock Aerial Gunnery Range was a World War II facility in two Nevada areas used for "aerial gunnery, strafing, dive bombing [and] rocket fire". By 21 November 1944, the Lovelock Range had been approved by the Secretary of the Navy to be developed for Naval Air Station Fallon, and on 13 January 1945, "Lovelock Air to Air" began when "leased under the Second War Powers Act". By February 1945, land was being acquired for the North Range in the Black Rock Desert which was 1,122 sq mi (2,910 km) that included 64.4 sq mi (167 km) of "Patented" (leased private) land. The South Range in the Granite Springs Valley was 2,436 sq mi (6,310 km), and in March 1945 "1920 Acres more" were added.

The post-war range was reactivated in October 1945 when the United States Navy closed more than 1,563 sq mi (4,050 km) to the public in the two Lovelock Aerial Gunnery Range regions. The Department of the Interior permit for the North Portion was cancelled by a 6 March 1946 letter, and the Bureau of Yards and Docks was directed to cancel the leases for the South Portion on 7 January 1947.

The Marias Massacre (also known as the Baker Massacre or the Piegan Massacre) was a massacre of Piegan Blackfeet Native peoples committed by United States Army forces under Major Eugene Mortimer Baker as part of the Indian Wars. The massacre occurred on January 23, 1870, in Montana Territory. Approximately 200 Native people were killed, most of whom were women, children, and older men.

As part of a campaign to suppress Mountain Chief's band of Piegan Blackfeet, the U.S. Army attacked a different band led by Chief Heavy Runner, to whom the United States government had previously promised their protection. This resulted in public outrage and a long-term shift towards a "Peace Policy" by the Federal Government, as advocated by President Ulysses S. Grant. Grant kept the Bureau of Indian Affairs as a division of the Department of the Interior although the War Department was trying to regain control. He then appointed men recommended by various religious clergy—including Quakers and Methodists—as Indian agents, in hopes that they would be free of the corruption he had previously found in the department.

A federally recognized tribe is a Native American tribe recognized by the United States Bureau of Indian Affairs as holding a government-to-government relationship with the US federal government. In the United States, the Native American tribe is a fundamental unit of sovereign tribal government. As the Department of the Interior explains, "federally recognized tribes are recognized as possessing certain inherent rights of self-government (i.e., tribal sovereignty)...." The constitution grants to the U.S. Congress the right to interact with tribes.

In the 1831 Supreme Court of the United States case Cherokee Nation v. Georgia Chief Justice of the United States John Marshall wrote that a Native American government is a "domestic dependent nation'" whose relationship to the United States is like that of a "ward to its guardian". The case was a landmark decision which led to the United States recognizing over 574 federally recognized tribal governments and 326 Indian reservations which are legally classified as domestic dependent nations with tribal sovereignty rights. The Supreme Court held in United States v. Sandoval "that Congress may bring a community or body of people within range of this power by arbitrarily calling them an Indian tribe, but only that in respect of distinctly Indian communities the questions whether, to what extent, and for what time they shall be recognized and dealt with as dependent tribes" (at 46). Federal tribal recognition grants to tribes the right to certain benefits, and is largely administered by the Bureau of Indian Affairs (BIA).

The United States has 154 protected areas known as national forests, covering 188,336,179 acres (762,169 km; 294,275 sq mi). National forests are managed by the U.S. Forest Service, an agency of the U.S. Department of Agriculture. The first national forest was established as the Yellowstone Park Timber and Land Reserve on March 30, 1891, then in the Department of the Interior. In 1897, the Organic Act provided purposes for which forest reserves could be established, including to reserve a supply of timber, protect the forest from development, and secure water supplies. With the Forest Reserve Act of 1891, the president of the United States is given the power to set aside forest reserves in the public domain. With the Transfer Act of 1905, forest reserves became part of the U.S. Department of Agriculture in the newly created U.S. Forest Service.

By 1907, President Theodore Roosevelt had more than doubled the forest-reserve acreage, and Congress responded by limiting the president's ability to proclaim new reserves. The National Forest System underwent a major reorganization in 1908, and in 1911 Congress authorized new additions to the system under the authority of the Weeks Act. The management goals provided by the Organic Act were expanded upon by the Multiple-Use Sustained-Yield Act of 1960 to include "outdoor recreation, range, timber, watershed, and wildlife and fish purposes" as well as for the establishment of wilderness areas.

Glen Canyon is a natural canyon carved by a 169.6-mile (272.9 km) length of the Colorado River, mostly in southeastern and south-central Utah, in the United States. Glen Canyon starts where Narrow Canyon ends, at the confluence of the Colorado River and the Dirty Devil River. A small part of the lower end of Glen Canyon extends into northern Arizona and terminates at Lee's Ferry, near the Vermilion Cliffs. Like the Grand Canyon farther downstream, Glen Canyon is part of the immense system of canyons carved by the Colorado River and its tributaries.

In 1963, a reservoir, Lake Powell, was created by the construction of the Glen Canyon Dam, in the Arizona portion of Glen Canyon near the brand new town of Page, inundating much of Glen Canyon under water hundreds of feet in depth. Contrary to popular belief, Lake Powell was not the result of negotiations over the controversial damming of the Green River within Dinosaur National Monument at Echo Park; the Echo Park Dam proposal was abandoned due to nationwide citizen pressure on Congress to do so. The Glen Canyon Dam remains a central issue for modern environmentalist movements. Beginning in the late 1990s, the Sierra Club and other organizations renewed the call to dismantle the dam and drain Lake Powell in Lower Glen Canyon. Today, Glen Canyon and Lake Powell are managed by the U.S. Department of the Interior within Glen Canyon National Recreation Area.
