    The plaeogeographic maps of the Colorado Plateau Region have been carefully prepared from published and unpublished stratigraphic and sedimentologic data and interpretations. For a recent synthesis of this material, see:

    Blakey, R. C., 2008, Pennsylvanian-Jurassic sedimentary basins of the Colorado Plateau and Southern Rocky Mountains in, Miall, A. D. (ed), Sedimentary Basins of United States and Canada: Elsevier, Amsterdam p. 245-296.
