The Great Basin is the largest area of contiguous endorheic watersheds – those with no outlets – in North America. It spans nearly all of Nevada, much of Utah, and portions of California, Idaho, Oregon, Wyoming, and Baja California, Mexico. It is noted for both its arid climate and the basin and range topography that varies from the North American low point at Badwater Basin in Death Valley to the highest point of the contiguous United States, less than 100 miles (160 km) away at the summit of Mount Whitney. The region spans several physiographic divisions, biomes, ecoregions, and deserts.

The Amargosa River is an intermittent waterway, 185 miles (298 km) long, in southern Nevada and eastern California in the United States. It drains a high desert region, the Amargosa Valley in the Amargosa Desert northwest of Las Vegas, into the Mojave Desert, and finally into Death Valley where it disappears into the ground aquifer. Except for a small portion of its route in the Amargosa Canyon in California and a small portion at Beatty, Nevada, the river flows above ground only after a rare rainstorm washes the region. A 26-mile (42 km) stretch of the river between Shoshone and Dumont Dunes is protected as a National Wild and Scenic River. At the south end of Tecopa Valley the Amargosa River Natural Area protects the habitat.

The Nellis Air Force Base Complex is the southern Nevada military region of federal facilities and lands, e.g., currently and formerly used for military and associated testing and training such as Atomic Energy Commission atmospheric nuclear detonations of the Cold War. The largest land area of the complex is the Nevada Test and Training Range, and numerous Formerly Used Defense Sites remain federal lands of the complex. Most of the facilities are controlled by the United States Air Force and/or the Bureau of Land Management, and many of the controlling units are based at Creech and Nellis Air Force Bases. Initiated by a 1939 military reconnaissance for a bombing range, federal acquisition began in 1940, and McCarren Field became the World War II training area's 1st of 3 Nevada World War II Army Airfields and 10 auxiliary fields. The area's first military unit was initially headquartered in the Las Vegas Federal Building while the WWII Las Vegas Army Airfield buildings were constructed.
