DAVIS: THE WASATCH, CANYON, AND HOUSE RANGES. 45 
in figure 21 (see also figure 17, and Plate 2, A, B); yet it causes very 
little disturbance in the monoclinal attitude of the layers. The south- 
ern end of the range seems to be determined by a somewhat steeper 
dip, whereby the resistant limestones that make the teeth of the saw 
descend with the crest of the range to lower and lower levels; but we 
diq not go far enough southward to determine just how the termina- 
tion of the range is brought about. In consequence of this south- 
ĉastward dip, the western escarpment of the Sawtooth mass gives an 
oblique section of the rock series which is of great significance, as will 
be more fully stated below. The general features of this escarpment 
are shown in figure 22, in which several sketches from different points 
are combined, thus giving the effect of a more distant view than was 
really taken. The fans are somewhat over-large for the height of 
the range. :

notch of the southern road on the left; the end of the range on the right. The 
spits built on their southern side. 
There is some indication of a transverse fault between the Swazy and 
Smoothback masses, for on viewing their escarpments from the playa 
on the west, the gray-and-slate colored cliffs which cap the promon- 
tories of the Swazy mass and the more continuous escarpment of the 
Smoothback mass do not seem to stand in the same plane; the south- 
ern seems to be several hundred feet lower than the northern, and the 
displacement apparently lies somewhat north of the ravine by which 
the northern road descends to the playa. Some local indications of 
Such a displacement, with the downthrow on the south, were noted 
as we came down the road in the ravine; an isolated knob north of 
the road had its cliff-making strata at apparently the same level as 
those on the south of the road, but lower by some 200 feet than the cor- 
responding strata in the next spur farther north, as in figure 23. The 
termination of several ridges on the eastern slope a little north of 
the northern road also suggests that they are prevented from con- 
tinuing farther south by a transverse fault.
