Salmon Site, site of nuclear weapons test
The Salmon Site is a former underground nuclear test location in Mississippi situated above the Tatum Salt Dome. The grounds cover a large area of forest and open fields, marked by a granite monument with a plaque and several test wells that document the scientific experiments conducted in the 1960s.
The site hosted two nuclear tests in the 1960s, with the first occurring in 1964 to help scientists understand how seismic waves travel after underground explosions. The second test followed in 1966 as part of programs designed to develop methods for detecting nuclear weapons testing from distant locations.
The site carries meaning for local residents as a reminder of Cold War era science and the costs of nuclear research on communities. Today it serves as a place where visitors can contemplate the relationship between technological progress and human concerns about safety and health.
Access to the grounds is restricted and carefully controlled by the government to ensure safety. Visitors should inquire in advance as the site is not regularly open to the public, and the surrounding area remains under monitoring.
The tests were so closely monitored that seismic equipment around the world, including stations in Finland, detected the underground explosions, ultimately proving that such detonations could not remain secret. This discovery later influenced international nuclear policy and arms control agreements.
