| Stratigraphy after Doelling and others (2000) and Hintze (1988). Please note: The thick nesses of stratigraphic units are highly variable across the large region encompassed by Grand Staircase - Escalante National Monument. The scale above on this composite section does not reflect this variability. For more detailed thickness of unit descriptions, see: Doelling, H. H ., Blackett, R. E., Hamblin, A. H., Powell, J. D., and Pollock, G. L., 2000, Geology of Grand Staircase - Escalante National Monument: In Geology of Utah's Parks and Monuments, Sprinkel, D.A., Chidsey, T. C., and Anderson, P. B., editors, Utah Geological Association Publication 28., p. 189-231. Hintze, L. F., 1988, Geologic History of Utah; A Field Guide to Utah's Rocks: Brigham Young University Geology Studies Special Publication 7. |

Click here to see a collection of modern and historic images of Grand Staircase - Escalante National Monument. Historic pictures were taken by the Thompson Expedition of the Powell Survey of 1872. Website images include both standard photograph and 3D views (as anaglyphs - requiring red-and-cyan 3D viewing glasses). This view taken along Highway 12 west of Boulder, Utah shows massive cliffs of Navajo Sandstone along the valley of Calf Creek in Grand Staircase - Escalante National Monument. |
