THE INDIVEDUAL PLATEAUS.

this preservation yields, when carefully studied, much information concern- 
ing the progress of the events which have made this region what it is. The 
western boundary of the Uinkaret is the Hurricane Ledge, which preserves 
its features throughout the entire length of the plateau and continues far 
beyond it with increasing emphasis to the northward. The eastern bound- 
ary is not so persistent. It consists in part of the Toroweap fault, which 
is a strong feature in the vicinity of the Grand Canon, but diminishes 
northward and finally dies out about 18 miles from the chasm. North of 
this thei’e is no structural and no resulting topographical feature separating 
the Uinkaret from the next subdivision. 
The Kanab Plateau is the broadest of the four, and the least pro- 
nounced in its features. It is a simple monotonous expanse, without a 
salient point to fix the attention, save one. This is a magnificent side 
canon, cutting through its central portion and opening into the heart of the 
Grand Canon. It is as instructive as it is magnificent. 
Next in order, east of the Kanab Plateau, rises the Kaibab. It is 
typical in its form, being nearly flat upon its summit and terminating in 
lofty battlements upon its eastern and western sides. It is much higher 
than the other three plateaus and has an elevation of 7,500 to 9,300 feet. 
Its broad surface is clothed with magnificent forest, opening in grassy parks, 
which during the summer are gay with flowers of rare beautv and luxuri- 
ance. It is a paradise to the explorer, who, weary of the desert, wanders 
with delight among its giant pines and spruces, and through its verdant 
but streamless valleys. This plateau is an uplift between two great dis- 
placements, throwing in opposite directions. Towards the north these con- 
verge, and near the little village of Paria., at the base of the Vermilion 
Cliffs, the western fault merges into the eastern and the plateau ends there 
in a cusp. The western fault in its southern portion splits into three, 
which die out upon the brink of the Grand Canon or hard by it. The 
eastern displacement is a monocline of huge proportions, and about mid- 
length it divides into two parallel monoclines, which die out upon the south- 
ern side of the Colorado. The total length of the Kaibab from the Ver- 
milion Cliff's to the Grand Canon is about 90 miles, and its width at a 
maximum about 35 miles.
