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.
The Uinkaret volcanic field is a resultant of the two-fault system, at the intersection region. Two example landforms, Vulcan's Throne, and Lava Falls both occur west of Toroweap Point, North Rim Grand Canyon, along the faults. A small volcano even occurs above the fault on the South Rim.
The 2-fault system is part of the west perimeter regions of the west, and southwest Colorado Plateau, called the High Plateaus Section.
