Nuclear Waste Adventure Trail and Museum: Weldon Spring, Missouri
The Nuclear Waste Adventure Trail and Museum, situated in Weldon Spring, Missouri, revolves around a accumulation of rocks, which serves as a mound for nuclear waste. The site encompasses a staggering 1.5 million cubic yards of hazardous waste. This location was previously home to the largest explosives factory in the United States, but in 1966, it was converted into a uranium ore processing plant. Following its abandonment, the US Department of Energy opted to cover the area with rocks.
