The Toadstool Hoodoos are a group of rock formations located in Grand Staircase-Escalante National Monument in Utah. They are named for their distinctive mushroom-like shape, which is the result of erosion over millions of years. The hoodoos are made of sandstone, which is a soft rock that is easily eroded by wind and water. The top layer of sandstone is harder than the bottom layer, which is why the hoodoos have a mushroom-like shape.
