SUBDIVISIONS OF THE GEAND AND MAEBLE CANONS. 23 
multitude of magnificent features which are either wanting or much less 
strongly represented elsewhere. If now we consider the Marble Canon with 
its southerly course, and the Kaibab division of the Grand Canon with its 
west and northwesterly course, we shall perceive that these two portions of 
the river form a great elbow or detour to the south. This detour is named 
the Eastern Bend. 
After passing the Kaibab division the chasm suddenly changes its 
course again from northwest to a direction a little south of due west, ex- 
tending in an almost straight line through the Kanab Plateau, a distance of 
forty miles. Here the chasm is about 5,O00 feet in depth, varying but little 
from that amount. It is also much simpler in form than in the Kaibab 
division. Along this portion two great side canons, as deep as the main 
chasm itself, open into it ; one from the north, called Kanab Canon, the 
other from the south, called Cataract Canon. The Kanab division ends at 
the foot of Toroweap Valley, a broad avenue about 20 miles long and two 
to three miles wide coming from the north. This valley is excavated only 
to about two-fifths of the depth of the chasm, and opens upon a broad plat- 
form in the main cation. The fault which runs through this valley drops 
the country to the west, and the height of the walls where the river crosses 
tlie fault at once diminishes from about 5,200 feet to 4,500 feet. But the 
lost altitude is soon regained. Here begins the Uinkaret division, which 
is about 15 miles in length. It is very similar in character to the Kanab 
division. At its termination the river again changes its course to the south- 
west and enters the Sheavwits Plateau. As the i-iver crosses the Hurricane 
fault the walls again drop and again the lost altitude is soon recovered. The 
general character of the canon in the Sheavwits division is similar to that 
of the Kanab. In this plateau the river makes a second great detour to the 
south, beginning with a southwesterly course, and after running about 40 
miles in this dii-ection suddenly deflecting to the northwest. This detour is 
named the Western Bend. The length of the Sheavwits division is about 
80 miles. At length the river emerges from this platform through a g’ate- 
way 5,000 feet in depth, and as it crosses the Grand Wash fault the walls 
at once drop to mere banks a few hundred feet in height with easy slopes, 
and the Grand Caiion ends.
