Amchitka Island

Amchitka Island is a remote island in Alaska's Aleutian Chain, historically used by the U.S. military and the nuclear testing program from the 1950s to the 1970s. It served as a site for underground nuclear tests to study seismic activity and nuclear technology. Despite its testing history, the island is now largely uninhabited and part of the Alaska Maritime Refuge, with ongoing environmental monitoring. The island’s remoteness has helped contain potential nuclear contamination, but its history remains significant for understanding Cold War-era military practices and nuclear safety.
