    Area 51

    The original rectangular base of 6 by 10 miles (10 by 16 km) is now part of the so-called "Groom box", a rectangular area, measuring 23 by 25 miles (37 by 40 km), of restricted airspace. The area is connected to the internal Nevada Test Site (NTS) road network, with paved roads leading south to Mercury and west to Yucca Flat. Leading northeast from the lake, the wide and well-maintained Groom Lake Road runs through a pass in the Jumbled Hills. The road formerly led to mines in the Groom basin...

    Groom Lake

    Groom Lake is a salt flat in Nevada used for runways of the Nellis Bombing Range Test Site airport (XTA/KXTA) on the north of the Area 51 USAF military installation. The lake at 4,409 ft (1,344 m) elevation is approximately 3+3⁄4 mi (6 km) from north to south and 3 mi (5 km) from east to west at its widest point. Located within the namesake Groom Lake Valley portion of the Tonopah Basin, the lake is 25 mi (40 km) south of Rachel, Nevada.

Security clearances are checked regularly; cameras and weaponry are not allowed. Even military pilots training in the NAFR risk disciplinary action if they stray into the exclusionary "box" surrounding Groom's airspace. Surveillance is supplemented using buried motion sensors. Area 51 is a common destination...

    Environmental lawsuit

    In 1994, five unnamed civilian contractors and the widows of contractors Walter Kasza and Robert Frost sued the Air Force and the United States Environmental Protection Agency. They alleged that they had been present when large quantities of unknown chemicals had been burned in open pits and trenches at Groom. Rutgers University biochemists analyzed biopsies from the complainants and found high levels of dioxin, dibenzofuran, and trichloroethylene in their body fat. The complainants alleged t...

    In December 2007, airline pilots noticed that the base had appeared in their aircraft navigation systems' latest Jeppesen database revision with the ICAO airport identifier code of KXTA and listed as "Homey Airport".
