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.
