Where can I go rockhounding on the Buffalo Gap National Grassland?
There are several exposed rock beds on Buffalo Gap National Grassland created by water erosion from the Black Hills as they formed between 40 and 60 million years ago. General locations for rock beds include: Conata Basin, Weta Basin, French Creek Campground and near Oelrichs, SD. See the Buffalo Gap Recreation map for these general locations. Little vegetation covers the river cobbles making up the rock beds so they are readily visible.
