Large boulders of Dakota sandstone are strewn completely across a broad valley in Bangs Canyon in western Colorado. The boulders near the bases of the sandstone cliffs at the valley sides form talus. The rest of the boulder distribution may be remnants of a rapid process that carved the valley. Giant boulders scattered as far away as 800 m from the cliff face seem to provide a counterexample to other Colorado Plateau cliffs where the talus stops abruptly near the base. This region has additional geologic features, such as peneplain erosion of the Precambrian strata; salt, coal and uranium deposits; and the large range of aeolian, riverine, lacustrine, marine and igneous deposits, which will be of interest for future studies by creationists.
