Black Hills Ordnance Depot

[1] 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,[2] a name derived because the characteristic shape of the munitions storage buildings constructed at the site has a similar appearance to igloos.

[1] Over the years, BHOD was used for storage and testing of chemical weapons, including sarin[4] and mustard gas.

[1] Once the Depot was closed, most of the residential housing units were moved to the Pine Ridge Indian Reservation.

The development now known as Vivos xPoint has become an international story and is currently in filming by a major cable network for an ongoing docu-series on the making of the world's largest survival community.
