lower canyon-section between Wheaton Creek Falls and Wheaton's
camp. This lowest level is important because it appears to
correlate with the presumed bed-rock of a dry, drift-filled
gulley, which extends southward from Wheaton's camp and along
which the trail runs from Wheaton's camp up the valley (see
Fig. 1). The direction of the dry gulley is significant, in-
asmuch as it heads towards, but is considerably below, the
rock bench east of Barrington's camp. It probably indicates
that a buried former strean channel lies east of, and at a
lower elevation than, the rock bench. The filled channel
probably approaches the present stream about a thousand feet
south-eastward from Sarrington's camp, at a point east of a
bed of limestone that outcrops along the trail. Kettle-holes
on the surface indicate that the channel is filled with gla-
cial material.

The valley of Wheaton Creek has widely-flaring sides
south of a point a mile south of the mouth of Alice Shea
Creek. The bottom is wide and bed-rock is exposed in many
places, but there are no rock bench remnants and only occa-
sional low gravel benches on the sides. The creek meanders
on a gentle grade, in one place by a drift ridge and in an-
other by a pot-hole lake. Drift is not deep in-the valley—
bottom, most: of it lies along the sides.

Tributaries of Wheaton Creek. Philippon Creek, a short
steep tributary of Wheaton joins it from the east about 1,000
feet south of the No. 1 post of the Philippon lease (No. 361).
The creek rises steeply (see Fig. 2) from its mouth but flat-
tens towards its head. The creek-valley is widely flaring.

In its lower stretch the creek flows in a shallow canyon part-
ly incised in bed-rock whereas towards its head the creek
flows over a thin veneer of glacial material. It is signifi-
cant that the down-stream projection of the flatter profile

of the upper part of the creek is only 10 feet above the high-
est bed-rock bench correlation along Wheaton Creek.

Alice Shea Creek is the one important gold-producing
tributary of Wheaton. It rises at the foot of Mt. Shea (see
ig. 3) flows northward for a mile and a half, then turns
westward and joins Wheaton Creek on the Peanut fraction
(lease No. 370) about 4 we miles south of the Turnagain.

In its lower course, on lease No. 353, Alice Shea Creek
flows in a narrow rock canyon having walls 50 to 75 feet high.
Up-stream from the canyon the creck is incised below the bot-
tom of a flaring valley and is flanked by drift covered rock
benches and walls 15 to 25 feet above creek-level. Through
the canyon, Alice Shea Creek flows on an average grade of 11.6
