6 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 
EXPLANATION OF PLATES. 
PLATE 1. 
. The front of the Spanish Wahsatch, looking south. The terminal facets of the 
spurs are here seen in profile. The Bonneville beach makes a bench at 
their base, and the beach is broken by a recent fault scarp a little forward 
from the mountain. The canyon of Spanish fork is in the middle distance, 
and the Mount Nebo division of the Wahsatch range rises beyond. 
. The front of the Spanish Wahsatch, looking east. The spurs and their terminal 
facets, separated by sharp-cut ravines, are here seen in full face view. The 
Bonneville beach is a light line just over the trees of the nearer fields. 
Plate 1, 4, was taken from the vertex of the triangular facet to the right of 
the mid-base of the northernmost spur. 
PLATE 2. 
. An unbroken fan at the base of the Pueblo mountains. A view down the can- 
yon from which this fan is supplied is given in Plate 5,8. Deegan’s house 
is close to the mouth of the canyon. The view is taken looking a little west 
of north. 
. Cane spring ranch and the Santa Rosa mountains. The ranch lies near the 
Lahontan shore line on the long slope of waste that is spread forth from the 
mountain ravines. 
PLATE 3. 
. The eastern face of the Pueblo mountains. The rounded spurs shown here 
contrast with the sharp-edged spurs of the Spanish Wahsatch, Plate 1, B. 
This part of the range stands between the two canyons shown in Plate 5. 
. The southern end of the Provo Wahsatch. The mountain spurs are terminated 
by well-defined triangular facets whose bases stand at the level of the Bonne- 
ville shere-line. The view is taken looking northeast. 
PLATE 4. 
. Rock canyon in the Provo Wahsatch. The walls of the canyon are more 
rugged than the front slope of the range. The view was taken from the 
roof of Provo Academy, looking northeast. 
. Slate canyon in the Provo Wahsatch. This repeats the features of the pre- 
vious view. It was taken from the same point, looking southeast.
