176 EXPLOITATION OF THE CANONS OF THE COLORADO. 
stand that the river cut its way through a region that was slowly rising 
above the level of the sea, and the rain washed out the valleys, and left 
rocks and cliffs standing, and the river never turned aside from its original 
course to seek an easier way, for the progress of uplifting was not greater 
than that of corrasion. Again we see how slowly the dry land has emerged 
from the sea; no great convulsion of nature, but steady progress. 
The Orange Cliffs, which terminate Labyrinth Caiion, extend to the 
west a few miles, and then change their course to the southwest, running 
parallel with the axis of the fold we are now discussing, and they cross the 
Dirty Devil a few miles above its mouth. Thus they are seen, like the 
other lines of cliffs, to face the axis of a fold. Figure 62 is a bird's-eye 
view, of this country, showing the course of the river through Still water, 
Cataract, and Narrow Canons. It represents the cutting of the stream into 
the slope of a mountain range, and out of it again, without crossing the 
range. On the left it shows two lines of cliffs. Here we have a district 
inclosed within Titanic walls. On ' the southeast are great mountains, and 
from the foot of their slope, on the north side, near Grand River, we find a 
line of cliffs crossing this stream, and extending to the Green, in a westerly 
direction; then' to the southwest, to the Dirty Devil River, and then broken 
and confused by buttes and canon walls, which extend toward the east, 
until it strikes the southern foot of the mountains. Within this walled area 
a profound gorge Cataract Caiion is seen, with Stillwater Canon above, 
and Narrow Canon below. The lower canon of the Grand is also seen, 
and a number of lateral canons. 
Along the genera'l slope of the district between the canons are vast 
numbers of buttes. Their origin is the same as that of the buttes previously 
described. Often they are but monuments, or standing columns of rocks. 
From them is derived the Indian name Toom'-pin Wu-near' Tu-weap' the 
Land of Standing Rocks. 
Adjacent to the larger canons, especially near the junction of the 
Grand and Green, walled coves are found. Each main gulch branches into 
a number of smaller gulches above, and each of these smaller gulches heads 
in an amphitheater. The escarpments of these amphitheaters are broken 
and terraced, and in many places two such amphitheaters are so close
