Sandstone caprock balanced atop eroding sediments, an example of a toadstool or hoodoo

The badlands are some of the fastest eroding landscapes on earth with erosion rates averaging 1” per year in their fragile layers. However, in areas where sandstone is found, the erosion rate may be 1” in 500 years. Often, toadstools form when surrounding sediments erode beneath a sandstone caprock.
