- Toroweap Formation
The coeval Toroweap Formation was laid down under marine conditions along the southwest margin of the North American continent and is found in northwest Arizona layered between Coconino Sandstone and the Kaibab Formation. The Toroweap is mostly from the Grand Canyon and just eastwards to Lee's Ferry-(Colorado River, Grand Canyon), south to the Verde Valley region (Sedona, Sycamore Canyon, Oak Creek Canyon), but the Toroweap also occurs within sections in southeast Utah, and also became overlain by the Kaibab Formation, specifically at the Circle Cliffs, west of the Waterpocket Fold.
Occurrences in Utah
Moab, Utah is located in southeast Utah, about 25 miles (40 km) west of the Colorado border. The Circle Cliffs lie about 90 miles (145 km) southwest from Moab, and east of Escalante and Boulder, Utah-(Utah State Route 12). The Circle Cliffs are located in the northeast of Grand Staircase-Escalante National Monument. The cliffs also extend north-northwest adjacent the west perimeter of the Waterpocket Fold, Capitol Reef National Park. The fold is traversed by Burr Trail Road-Straton Road which has views toward the Circle Cliffs, southward, or westward.
