Located in the most northwestern corner of Nebraska, north of Crawford, you'll find the expansive landscape of the Oglala National Grasslands. This unique area consists of native mixed-grass prairie, with forested streambeds and steep, worn, formations created by water and wind erosion on layers of siltstone, and clay. Find your way to the Hudson-Meng Bone Bed site where you can take a tour and learn about the history of this area, walk through the unique features of the Toadstool Geologic Park , or just spend some quiet time in the wide open spaces of the 94,000 acres of mixed grass prairies. The Oglala Grassland is the best place in Nebraska to view pronghorns and a popular place to view prairie dog colonies along the site’s northern border.
