The Toroweap Fault of northwest Arizona and southwest Utah is part of a fault system of the west Grand Canyon region, Arizona, US ; also the west perimeter regions of the Coconino and Colorado Plateaus . The Hurricane Fault originates at the Toroweap Fault, in the region of the Colorado River , and strikes as the westerly depression of the Toroweap Fault. The Toroweap strikes northerly from the Colorado at the east of Toroweap Valley, and enters south Utah; from the Colorado River, the Hurricane Fault strikes north-northwest along the west flank of the small, regional Uinkaret Mountains , the west border of Toroweap Valley. The Hurricane Fault, and the Hurricane Cliffs strike into southwest Utah as part of the west, and southwest perimeter of the Colorado Plateau . The Hurricane Cliffs are made of Kaibab Limestone , an erosion resistant, cliff-forming rock unit.

While some believe that these lava dams were stable, lasting up to 20,000 years and forming large reservoirs, others think they failed quickly and catastrophically as massive floods. Lava flows traveled downriver 76 miles (121 km) from river mile 178 to 254. One lava flow, from Little Springs, south of Pliocene Mount Trumbull , has
