Badlands

Badlands are a type of arid terrain with clay-rich soil that has been extensively eroded by wind and water. Canyons, ravines[?], gullies[?], hoodoos and other such geological forms are common in badlands.

Some of the most famous fossil beds are found in badlands, where the forces of erosion have exposed the sedimentary layers and the lack of vegetation cover makes surveying relatively easy.
