DAVIS: THE WASATCH, CANYON, AND HOUSE RANGES. 31 
of the slide, like that of the inferred faulting of the mountain block, 
must be much less recent than that of the little slide and the modern 
faults along the base of the Nebo Wasatch. The size of the slide was 
surprising; 1t stretched continuously along the mountain base for at 
least two miles; its forward reach was estimated at two miles and a 
half; its height next to the mountain side must have been at least 500 
feet, and probably more. The contact of the slide with the mountain 
side was rather well shown on the sides of a small valley which cut 
through both. The mountain face, there protected, seemed steeper 
than elsewhere. Several slides of similar character but of smaller size 
Were seen farther south. 
We spent the afternoon and night at Oak City, a small town that is 
hills south of Oak City. A great landslide stretches westward from the range 
irrigated by a stream from the neighboring range. Our camp was in 
a grassy orchard of apple and peach trees belonging to Mr. Fred 
Lyman. A sketch of the canyon range and the great landslide, fig- 
ure 10, was made looking north from the hills south of the town 
about sunset: the slide extends in the distance from the middle of 
the right half of the figure to the first third of the left half. Part 
of the same view is shown in Plate 1, B. Our host made inquiries 
about the spur formed by the slide, saying that he had been much 
Puzzled by it; he had looked into Leconte’s “Elements of Geology,” 
In hopes of there learning something about its origin, and had won- 
dered if it could possibly be a great moraine, but had felt doubtful of 
Such an origin because there was no mountain high enough above it 
to have fed a large glacier. He accepted our explanation that the 
Spur is an old landslide, although against this explanation also there 
IS the manifest objection that the mountain does not now seem high 
Or steep enough to have provoked a fall. The evident answer to 
this objection is that the mountain may have been steeper and higher
