Lake Mead National Recreation Area is a U.S. national recreation area in southeastern Nevada and northwestern Arizona. Operated by the National Park Service, Lake Mead NRA follows the Colorado River corridor from the westernmost boundary of Grand Canyon National Park to just north of the cities of Laughlin, Nevada and Bullhead City, Arizona.

The protected areas of the United States are managed by an array of different federal, state, tribal and local level authorities and receive widely varying levels of protection. Some areas are managed as wilderness, while others are operated with acceptable commercial exploitation. As of 2020, the 36,283 protected areas covered 1,118,917 km2 (432,016 sq mi), or 12 percent of the land area of the United States. This is also one-tenth of the protected land area of the world. The U.S. also had a total of 787 National Marine Protected Areas, covering an additional 3,210,908 km2 (1,239,739 sq mi), or 37 percent of the total marine area of the United States.
The Tonto National Forest, encompassing 2,873,200 acres, is the largest of the six national forests in Arizona and is the fifth largest national forest in the United States. The forest has diverse scenery, with elevations ranging from 1,400 feet in the Sonoran Desert to 7,400 feet in the ponderosa pine forests of the Mogollon Rim. The Tonto National Forest is also the most visited "urban" forest in the United States.
The Paria Canyon-Vermilion Cliffs Wilderness is a 112,500 acres (455 km2) wilderness area located in northern Arizona and southern Utah, United States, within the arid Colorado Plateau region. The wilderness is composed of broad plateaus, tall escarpments, and deep canyons.
The Flathead National Forest is a national forest in the western part of the U.S. state of Montana. The forest lies primarily in Flathead County, south of Glacier National Park.

The Arizona Strip is the part of Arizona lying north of the Colorado River. Despite being larger in area than several U.S. states, the entire region has a population of fewer than 10,000 people. Consisting of northeastern Mohave County and northwestern Coconino County, the largest settlements in the Strip are Colorado City, Fredonia, and Beaver Dam, with smaller communities of Scenic, Littlefield and Desert Springs. The Kaibab Indian Reservation lies within the region. Lying along the North Rim of the Grand Canyon creates physical barriers to the rest of Arizona. Only three major roads traverse the region, I-15 crosses the northwestern corner while Arizona State Route 389 and U.S. Route 89A crosses the northeastern part of the strip, US 89A crosses the Colorado River via the Navajo Bridge, providing the only direct road connection between the strip and the rest of the state. The nearest metropolitan area is the St. George, Utah metro area, to which the region is more connected than to the rest of Arizona.
The National Wilderness Preservation System (NWPS) of the United States protects federally managed wilderness areas designated for preservation in their natural condition. Activity on formally designated wilderness areas is coordinated by the National Wilderness Preservation System. Wilderness areas are managed by four federal land management agencies: the National Park Service, the U.S. Forest Service, the U.S. Fish and Wildlife Service, and the Bureau of Land Management.
The Big Maria Mountains are located in the southeastern part of the U.S. state of California, near the Colorado River and Arizona. The range lies between Blythe and Vidal, and west of U.S. Route 95 in California and east of Midland. The mountains are home to the Eagle Nest Mine and reach an elevation of 1,030 meters, (3,379 ft). A power line that runs from Parker Dam to Yuma, Arizona runs through the range. A smaller range, the Little Maria Mountains, lie to the west of the Big Marias.
The Little Picacho Wilderness is a 38,214-acre (15,465 ha) wilderness area under the jurisdiction of the Bureau of Land Management. The wilderness is found in a southeast extension of the Chocolate Mountains adjacent to the Colorado River, in the southeastern part of California. It should not be confused with the Picacho Peak Wilderness which is located to the northeast.
The Bigelow Cholla Garden Wilderness is in the eastern Mojave Desert and within Mojave Trails National Monument, located in San Bernardino County, California.
National Conservation Lands, formally known as the National Landscape Conservation System, is a 35-million-acre (140,000 km2) collection of lands in 873 federally recognized areas considered to be the crown jewels of the American West. These lands represent 10% of the 258 million acres (1,040,000 km2) managed by the Bureau of Land Management (BLM). The BLM is the largest federal public land manager and is responsible for over 40% of all the federal public land in the nation. The other major federal public land managers include the US Forest Service (USFS), National Park Service (NPS), and the US Fish and Wildlife Service (USFWS).
The Black Ridge Canyons Wilderness (BRCW) is located in western Colorado with a small portion extending into eastern Utah, USA, within the arid Colorado Plateau region approximately 15 miles (24 km) west of Grand Junction, Colorado. The wilderness lies on the northwest flank of the Uncompahgre Plateau. It is characterized by the high, east-west trending Black Ridge dissected by seven major canyon systems, draining into the Colorado River in Ruby Canyon. Elevations range from 4,700 feet (1,400 m) above sea level along the river to 6,800 feet (2,070 m). Canyons vary in length from several miles to twelve miles in length and may contain interesting side canyons. Geological features in these canyons include spires, windows, giant alcoves and desert varnish. Canyons may reach a depth of almost 1,000 feet (300 m), forming spectacular redrock cliffs. Spring runoff and summer thunderstorms create glistening waterfalls and plunge pools. Rattlesnake Canyon contains the second largest concentration of natural arches in the country. Mee Canyon is even more remote, and contains Arch Tower.
The Cedar Mountain Wilderness is located in northwestern Utah, United States, just south of Interstate 80. The vegetation on the upper elevations of the Cedar Mountains is dominated by junipers. The foothill and valley regions include mixed desert shrubs. Cheatgrass is prevalent over large areas burned by range fires. The remains of an aragonite mining camp can also be found in the foothills.
Canyons of the Ancients National Monument is a national monument protecting an archaeologically-significant landscape located in the southwestern region of the U.S. state of Colorado. The monument's 176,056 acres (71,247 ha) are managed by the Bureau of Land Management, as directed in the Presidential proclamation which created the site on June 9, 2000. Canyons of the Ancients National Monument is part of the National Landscape Conservation System, better known as the National Conservation Lands. This system comprises 32 million acres managed by the Bureau of Land Management to conserve, protect, and restore these nationally significant landscapes recognized for their outstanding cultural, ecological, and scientific values. Canyons of the Ancients encompasses and surrounds three of the four separate sections of Hovenweep National Monument, which is administered by the National Park Service. The monument was proclaimed in order to preserve the largest concentration of archaeological sites in the United States, primarily Ancestral Puebloan ruins. As of 2005, over 6,000 individual archeological sites had been identified within the monument.

The wilderness is approximately 27 miles (43 km) from north to south and 39 miles (63 km) east to west. U.S. Wilderness Areas do not allow motorized or mechanized vehicles, including bicycles. Camping, hunting, and fishing are allowed with proper permit, but no roads, buildings, logging, or mining are permitted. Wilderness areas within National Forests and Bureau of Land Management areas allow hunting in season.
The Beaver Dam Wash is a seasonal stream near the southwestern Utah-Nevada border in the United States. At its southern end in northern Arizona, near the point where it empties into the Virgin River, the stream flows throughout the year. Part of the wash is in the Beaver Dam Wash National Conservation Area, managed by the Bureau of Land Management. The wash was so named on account of beaver dams which once were built on its course.
Doc's Pass Wilderness is a 17,294-acre (70.0 km2) wilderness area in the US state of Utah. It was designated March 30, 2009, as part of the Omnibus Public Land Management Act of 2009.
