Granite Peak Installation, Military testing facility in Utah, US.
Granite Peak Installation is a military facility within Dugway Proving Ground containing laboratory buildings, residential quarters, and a medical facility. The site operated with its own utility systems, an airstrip, and paved road networks serving its self-contained operations.
The installation was built in 1943 as the primary testing site for biological weapons by the United States military during World War II. It served for decades as a center for military experimental programs.
The facility contributed to military scientific advancement through various experimental programs, including tests with the M33 cluster bomb and biological agents.
The site is geographically separated from the main Dugway Proving Ground and was designed as an independent operating complex. Visitors should expect remote conditions and limited accessibility to the area.
Only two structures remained at the site by 1985: a pump house and an underground storage building. These sparse remnants reflect the complex's former scale.
