A mushroom rock, also called rock pedestal, or a pedestal rock, is a naturally occurring rock whose shape, as its name implies, resembles a mushroom. The rocks are deformed in a number of different ways: by erosion and weathering, glacial action, or from a sudden disturbance.Pedestal rocks generally form in sandstone/shale terrains, with differential erosion producing a sandstone cap on a shale base.
