Niobrara formation

Unlike other rivers on the Great Plains, the Niobrara is rapidly eroding (on a geologic time scale), cutting down into ancient formations that formerly lay buried beneath the river. The result is that the river is confined to a narrow valley over much of its designated 76-mile length, with high cliffs looming over portions of the river, and rocks and rapids greeting canoers. Ponderosa pine ...
