Benches. Benches are a prominent and important feature
of the stretch of Wheaton Creek valley that lies down-stream
from a point a mile south of the mouth of Alice Shea Creek
(see Figs. 1 and 2). North of the mouth of Philippon Creek,
on the Amanda, slice and Roosevelt leases, there are high
gravel benches on both sides of the creek and from 200 to 250
feet above it. These bench remnants, though not continuous,
may be correlated on one side of the creek or the other, but
not from one side to the other. They extend for a mile or
more along the sides. Rock bench remnants are more important,
though not always more prominent than the gravel benches.
These have been observed and correlated from Wheaton Creek
Falls, southward along the creek to a point a mile south of
the mouth of Alice Shea Creek. The rock bench remnants range
from a few feet to as much as 200 feet above the creek, and
may be bare rock, or covered with a few feet of gravel or
with glacial boulder-clay. In Fig. 2, which is a longitudin-
al profile of Wheaton Creek and its tributaries, Philippon
and Alice Shea Creeks, transverse profiles are drawn at vari-
ous points along the valley. The bench correlations are made
on this basis. The benches are correlated on four separate
and distinct levels, each of which represents a stage in the
down-cutting of the stream. The rock bench remnants, which a
mile or so above Alice Shea Creek, are at or just above
creek-level, are correlated with down-stream remnants that are
progressively higher than the creek. It is apparent that this
upper level is the down-stream extension of the Wheaton Creek
valley-bottom that lies south of a point a mile up-stream
from the mouth of Alice Shea. This, the highest level, with
a grade of 1.2 per cent., represents the oldest valley-bottom
of Wheaton Creek, and it is interesting to note that straight
line projections of the upper courses of both Pia Pepper and
flice Shea Creeks are only slightly above it.

A second lower correlated level extends through the
Alice, Roosevelt and Peacock leases. The farthest down-stream
point to which a correlation could be made is a small rock
bench below the falls on a small side creek entering Wheaton
just south of the Barrington camp.

A third, more important level, is the correlation of an
inconspicuous rock bench at Bobner's camp, with the sand and
gravel-covered rock bench lying 25 to 30 feet higher than and
to the east of Barrington's camp, and with the bare high rock
bench remnants flanking the lower canyon-section of Wheaton
Creek.

A fourth, and lowest level, is the correlation of the
low rock bench remnants that lie along Wheaton Creek in the
