The White River Bad Lands is the most im-
portant Bad Land area in the world. Nowhere
in the world can the influence of erosion be
better studied or more easily understood.
This area lies chiefly in southwestern South
Dakota. No place shows better how the Lord
built up the rocks and soils of the land.
Layers of muds, sands and gravels were laid
8 down through unnumbered years and were
accompanied by animals that were suited
to the weather and geography of the time.
This is the reason that tossils of different
animals are found at different layers of depth
in the Bad Lands.
