The Badlands began eroding about 500,000 ...

The sediments that make up shale are tightly packed, this arrangement means that shale, unlike limestone, is not a porous rock. One of the shales at Mammoth Cave formed about 320 million years ago as the shallow sea receded and returned, depositing layers of shale above the limestone beds the cave is formed in.Shale is a fine-grained sedimentary rock that is formed when silt and clay are compressed. It is composed of many thin layers, and it readily splits into thin pieces where these layers meet—making it a relatively brittle stone. [2] Shale is composed of small grains and various minerals along with organic particles.

The Permian Hermit Formation, also known as the Hermit Shale, is a nonresistant unit that is composed of slope-forming reddish brown siltstone, mudstone, and very fine-grained sandstone.
