Weldon Spring Site

  • 7295 Hwy. 94 South, Saint Charles, MO 63304

The Weldon Spring Site has transformed from a site once used to manufacture explosives and process uranium-ore concentrates to a publicly accessible area for recreation and education.

To preserve the history of the Weldon Spring site and tell the story of its interesting past, DOE remodeled one of the buildings at the site into a 10,663-square-foot Interpretive Center Museum. Visitors can now hike or bike the Hamburg Trail through the site, climb to the top of the disposal cell to view the expanse of prairie in bloom at various times of the year, and tour the Interpretive Center and Native Plant Educational Garden. The Native Plant Educational Garden contains extensive plantings of species from the Howell Prairie as well as other perennials, shrubs, and trees.
