The Vermilion Cliffs are steep eroded escarpments consisting primarily of sandstone, siltstone, limestone, and shale which rise as much as 3,000 feet (915 meters) above their bases. These sedimentary rocks have been deeply eroded for millions of years, exposing hundreds of layers of richly colored rock strata. Mesas, buttes, and large tablelands are interspersed with somne steep canyons, where some small streams provide enough moisture to support a sampling of wildlife. (Source Wikipedia)
