North Dakota Badlands
The badlands you see from here were so named because they were "badlands" to travel over before modern roads were built. Rain, wind and running water have carved these hills. A thick series of shale and sandstone layers, all of these rocks are a part of the Fort Union Formation ( Paleocene Age). Once part of the High Plains, this area has been deeply eroded. Flash floods which follow every storm are still cutting away the rock layers.
