The Bisti Wilderness area is a rolling landscape of badlands. Time and natural elements have etched a fantasy world of strange rock formations made of interbedded sandstone, shale, mudstone, coal, and silt. The weathering of the sandstone forms hoodoos - weathered rock in the form of pinnacles, spires, cap rocks, and other unusual forms. Fossils occur in this sedimentary landform. Translated from the Navajo language, Bisti means "a large area of shale hills."
