The Weldon Spring Site Interpretive Center highlights site history, cleanup activities, and current site conditions and is an important component to area school curriculum in teaching STEM subjects, the history of the site, and the natural beauty of the plants, animals and habitats the Weldon Spring Site features.
Adjacent to the Interpretive Center and completed in 2001, the Weldon Spring Disposal Cell stands about 75 feet tall, covers approximately 1 mile in circumference, and consists of a 41-acre structure containing 1.48 million cubic yards of waste.
Stairs to the top of the cell and viewfinders at the top offer a panoramic view of portions of both St. Charles and St. Louis counties. Visitors can also walk around the cell's 41-acre perimeter or visit the Interpretive Center. The site is free and open to the public.
A native plant garden with paths and benches welcomes visitors to the site. The 150-acre planted Howell Prairie features a wide variety of plants and wildlife and may be viewed from several trails and the disposal cell.
The site serves as a trailhead to the multiuse 6-mile Hamburg Trail with connections to Missouri Department of Conservation trail systems, the Great Rivers Greenway trail network, and the historic Katy Trail State Park trail that stretches across the state along the Missouri River.
LM’s Weldon Spring Site in Missouri represents a long legacy of service and a commitment to site cleanup and restoration.
