Named for the Grand Wash Trough which was formed by the "faulting and tilting of a large crust block" (US-T121) "faulting and tilting of a large crust block" (US-T121). The cliffs rise like steps from the lowland area to the high plateaus. The north end is at 363130N 1134700W. The south end is at 352300N 1134200W. plateaus: The north end is at 363130N 1134700W. The south end is at 352300N 1134200W. This locality is not listed in the USGS MRDS database.

GRAND WASH CLIFFS.

The Grand Wash Cliffs constitute the great break of the Colorado Plateau into the Great Basin. They undoubtedly represent a fault line, as has been described by previous writers, and are so shown on the accompanying map (Plate I). Dutton describes the Grand Wash fault as a gigantic displacement in which the whole country to the west has dropped down 6,000 or 7,000 feet. This fault is best developed along the edge of the plateau, extending from the mouth of the Grand Canyon southeastward to Music Mountain, a distance of about 50 miles, with a height of escarpment of about 3,000 feet and an average width of about 3 miles. The regularity of its course is locally interrupted by embayments or short, deep canyons cut back into the plateau, the most marked example being that at Clay Spring, north of Music Mountain camp.

From the edge of the plateau the general trend of the slope is westsouthwest into Hualpai Valley. Typically this slope is made up of three topographic elements; these are, in descending order, (1) an upper; more or less precipitous cliff or scarp, a-bout 1,500 feet in height, composed of the nearly horizontal strata of the Grand Canyon section; (2) an intermediate mountainous belt, in many places steep and rugged, composed of pre-Cambrian rocks having a vertical range of 1,000 or more feet and a breadth of about 2 miles; (3) a less steep foothill belt of irregular hills and ridges, consisting of similar granitoid rocks, which, with immense local deposits or fans of steep-lying talus or coarse, mostly granitoid, debris, descend from 600 to 1,000 feet to the edge of the valley.

At Music Mountain the Grand Wash Cliffs divide, the upper or sedimentary portion extending eastward under the name of Yampai Cliffs, and the lower or crystalline portion continuing southward under the names of Cottonwood Cliffs and Aquarius Cliffs, forming the edge of the Truxton Plateau.
