The Bentonite Hills in Capitol Reef National Park can in the right light be very colorful and are sometimes called Rainbow Bentonite. They are a remnant of volcanic ash and look like colorful styrofoam packing material. Beneath this is clay which can absorb large amounts of water and was used by the pioneers to seal roofs and also to lubricate wagon wheels. This also make the trails impassable in the rain.
