Toroweap Fault

Two example landforms, Vulcan's Throne, and Lava Falls both occur west of Toroweap Point, North Rim Grand Canyon, along the faults.

They extend from the Colorado River south to Prospect Valley, its east perimeter, jump through a mountainous stretch to the north of Aubrey Valley, the cliffs forming its east and southeast border, with the south terminus, Chino Point, just west of Seligman, Arizona, at Interstate 40.

In the south at Aubrey Valley, the Coconino Sandstone is reduced to a thin member, compared to the up to 300 ft cliff maxima at Grand Canyon locales.

Prospect Valley is very narrow; the south half is endorheic; the north drains directly into the Colorado River, just west of the Toroweap Overlook.

The faults at the Aquarius Cliffs are "high angle normal faults",[5] explaining the Aquarius Cliffs—Big Sandy River & Valley—Hualapai Mountains region as: "Colorado Plateau, east; Hualapai Mountains, classic Basin and Range; and south, 'Highly Extended Terranes',[6] (also Basin and Range, southeast Mojave Desert meeting northwest Sonoran Desert).
