Its name was inspired by the narrow clay pedestals topped with slabs of sandstone that resemble toadstool mushrooms. It is one of the most memorable places in the grassland with its unique layers, formations, and scientifically valuable fossil deposits. Toadstool is a key link in understanding the earth's history from 38 to 24 million years ago. Formed by mostly volcanic ash and alluvial river deposits, geologists consider it the "type section for the White River Geologic Group", meaning that all other similar-aged deposits in North America are compared to the geological standard designated at Toadstool.
