Black Hills Ordnance Depot

The Black Hills Ordnance Depot was a munitions storage and maintenance facility formerly operated by the Ordnance Corps of the United States Army. The depot was located in Fall River County, in far southwestern South Dakota about eight miles south of the town of Edgemont.
BHOD was established and constructed in 1942, to help meet the Army's increased ordnance handling needs caused by World War II. Because of the relative remoteness of the location, nearly all of the facility's civilian workforce lived in federally owned housing at the depot; this residential community was known as Igloo, a name derived because the characteristic shape of the munitions storage buildings constructed at the site has a similar appearance to igloos. The Igloo community included public schools, a hospital, post office, church, and shopping and entertainment facilities including a theater, swimming pool and a recreation center.
