Rock Hounding in Rapid City, South Dakota
The nation's oldest mountain range, the Black Hills and the Badlands areas, provide a nearly complete stratigraphic history. The Hills are among the top five locations in the U.S. for mineral mining—more than 140 can be found here. Mineral collections can be viewed at the Museum of Geology at the South Dakota School of Mines and Technology in Rapid City. Rock collecting advice is available from rock shops in the area or from local gem and mineral societies.
Collecting from within Badlands National Park and historical sites located in the Black Hills National Forest is not permitted. The Buffalo Gap National Grassland which surrounds the park does allow rock collecting and even has some very large areas allocated for that purpose. Because the Grassland does also include some private land, you need to make sure you are on public property or obtain permission from the landowner.
