Eroded claystone and sandstone buttes striped in ash and ancient soil, breaking a mixed-grass prairie. Fossil beds of the White River Group.
French-Canadian trappers called it les mauvaises terres à traverser — bad lands to travel across. Dawn and dusk turn the stripes peach and violet. Bison still graze the grass between the buttes.
