SUEPEISE VALLEY.

pice, on the left a lofty ridge of the same, and in front is the great preci- 
pice again. Ont of a lateral chasm on the right there flows a large creek of 
water, clear as crystal, and dashing merrily along its rocky bed. It 
emerges from a cavern in the cliff and passes right across the lower end of 
the valley ; but whither does it go ? It seems to enter the inclosing ridge 
on the left. Following the stream a few hundred yards the ridge is seen 
to be cleft transversely by a cut 50 or 60 feet wide and 700 or 800 feet 
deep. The cleft winds out of sight into its mass. Leaving the animals 
and entering its opening there is seen to be a deeper and narrower cleft 
about 12 feet wide into which, by a succession of cascades, the brook 
plunges. At the top of the lower and narrower cleft is a shelf, along which 
we may walk. The width of this shelf contracts and the walls begin to 
overhang. As we progress it becomes only three or four feet wide and the 
overhang is so low that we must creep on hands and knees. Beside us is 
the fissure, and the reverberations of the water come up from unseen depths 
which appear by the sound to be great. Soon the shelf widens again and 
the roof rises higher so that we may walk erect. A few hundred yards be- 
yond we emerge into full daylight again upon the brink of a clitf about. 450 
feet high. At the bottom flows the Colorado River. A little to the west 
the clilf is shattei’ed, and there we may descend to the water’s edge and 
refresh ourselves. Here the river is about to flow out of the “granite,” for 
the gentle dip of the whole stratigraphic system towards the west canles 
the horizons downward at a rate more rapid than the fall of the river. Here, 
too, is the beginning of the Kanab division of the Grrand Canon. 
There is little here of interest to the geologist beyond what will be, or 
what has been, described in this work in more general terms. I have 
indulged in this digression to convey graphically an idea of the canon wall 
and to indicate the difficulties which attend an examination of points within 
the chasm. Let us, therefore, return the way we came. 
Leaving Parusi-wompats Spring, a faint trail leads to the southwest- 
ward, winding through the forest and across ravines and gulches. A ride 
of two or three hours brings us once more to the brink; here is a wide gap, 
separating the main Kaibab platform from a large outlying mass named
