Mushroom Rock State Park

Mushroom Rock State Park, located in the Smoky Hills region of north-central Kansas, is noted for its mushroom rock formations. These mushroom rocks are an example of hoodoos, formed through a process of nonuniform erosion and weathering in which a hard mass of Dakota Sandstone capstone resisted erosion while the underlying softer stone weathered away. There are two mushrooms and a giant shoe rock, as well as numerous other rock formations in the 5-acre (2.0 ha) park.
