Weldon Spring Ordnance Works

Weldon Spring Ordnance Works is a former military manufacturing facility that now encompasses restored lands and nature reserves spread across a large area west of St. Louis. The site includes remnants of industrial buildings alongside forests and open spaces, showing how the grounds have been transformed into accessible outdoor areas.

During World War II, from 1941 to 1945, the facility produced explosives for American military operations. After the war ended, the site was closed and later underwent extensive cleanup efforts to address environmental contamination left behind from manufacturing.

The grounds were transformed into conservation areas where visitors can walk through restored landscapes and wildlife habitats. This transformation shows how a former industrial site became a place for nature and recreation.

The site is accessible through several entry points with marked trails for visitors wanting to explore the restored areas. Spring and fall offer ideal conditions for walking, as the weather is mild and paths are generally well-maintained.

The grounds were later used as a disposal site for radioactive uranium processing waste after the war, making remediation efforts particularly complex and ongoing. This history of industrial reuse reveals how environmental cleanup at such large sites takes decades to complete.
