| Summary |
"St. Joe State Park, approximately 65 miles south of St. Louis, Missouri, was the site of lead and zinc mining operations for over 100 years. Operations at the mine by the St. Joe Minerals Corporation included pumping mine tailings in a slurry up the nearby river valley. The site was donated to The State of Missouri by St. Joe Minerals Corporation when mining operations ceased in 1972. After taking possession The State converted the milling house into a museum and the surrounding areas into off-road vehicle tracks and campgrounds. The United States Geological Survey (USGS) is currently conducting a hydrogeologic investigation of the site to characterize potential environmental impacts the lead and zinc tailings could have on the health and safety of visitors and surrounding residents. In an attempt to aid the USGS in this task, a geophysical study was undertaken using electromagnetic induction, 2-D resistivity and multi-channel analysis of surface waves to map the water table and the original bedrock surface of the valley"--Abstract, leaf iii. |
