Dugway Proving Grounds
Dugway Proving Ground (DPG) is a US Army facility established in 1942 to test biological and chemical weapons, located about 85 miles (140 km) southwest of Salt Lake City, Utah and 13 miles south of the 2,624 sq mi Utah Test and Training Range forming the largest overland special use airspace in the United States. In 1968 more than 6,000 sheep were killed in the Dugway sheep incident. In 2015 it was revealed that the Dugway lab had inadvertently shipped live anthrax spores.
Dugway Proving Ground is located about 85 miles (140 km) southwest of Salt Lake City, Utah, in southern Tooele County and just north of Juab County. It encompasses 801,505 acres (3,243 km², or 1,252 sq mi) of the Great Salt Lake Desert, an area the size of the state of Rhode Island, and is surrounded on three sides by mountain ranges. It had a resident population of 795 persons as of the 2010 United States Census, all of whom lived in the community of Dugway, Utah, at its extreme eastern end.
It is 13 mi (21 km) south of the 2,624-square-mile (6,796 km2) Utah Test and Training Range and together they form "the largest block of overland contiguous special use airspace measured from surface or near surface within the continental U.S. (207 by 122 nautical miles)" (383 by 226 km).
The transcontinental Lincoln Highway passed through the present site of the Dugway Proving Ground, and is the only section of the old highway closed to the public. At least one old wooden bridge over a creek still stands. The name Dugway comes from a technique of digging a trench into a hillside to create a flat surface along which a wagon can travel.
Dugway's mission is to test US and Allied biological and chemical weapon defense systems in a secure and isolated environment. DPG also serves as a facility for US Army Reserve and US National Guard maneuver training, and US Air Force flight tests—mostly from nearby Hill Air Force Base in Clearfield. DPG is controlled by the United States Army Test and Evaluation Command (ATEC). The area has also been used by Army special forces for training in preparation for deployments to the War in Afghanistan.
