THE UINTA CANONS. 157 
at least, of the apparent upheaval above mentioned may be accounted for 
by a depression of the formations in synclinal folds, and the letting down 
of broad areas of the earth's surface by lateral contraction exhibited in 
corrugation. 
When we arrive at a point a few miles north of Flaming Gorge, we 
strike the flank of this great fold, and find the rocks dipping to the north, 
and, as we run south, the course of the stream is against the inclination of 
the beds; and this is true, in the main, until we reach Bee Hive Point, where 
the river turns to the east, almost at right angles to its former course, and 
to the dip; then it runs nearly in the direction of the strike, but the axis is 
not crossed until after passing through Red Canon. The rocks on both 
sides of this canon dip to the north; that is, they incline to the river on the 
south, and from it on the north. Under these conditions, the two walls of 
Red Canon present very different characteristics ; that on the south exhibits 
steep slopes, covered, to a greater or lesser extent, with forests; the north 
wall is a bold escarpment, often vertical, and almost treeless; high cliffs, set 
with pinnacles and towers, and narrow side canons, are its salient features. 
From the foot of Red Canon to the Gate of Lodore, a distance of more 
than thirty miles, the river runs through a valley known as Brown's Park, 
five or six miles wide, and enclosed by mountains. It is a curious fact that 
the central line of this valley corresponds to the axis of the fold; that is, 
had the fold been made, and left without erosion, the very summit would 
have been directly above the deepest part of the park. 
When we enter the Gate of Lodore, we are in rocks dipping to the 
south, having crossed the axis of the fold. From here to Split Mountain 
Canon the general course is southwest, hence not directly across the dip, but
