stretch averages about 1,500 feet in width. Three-quarters of a mile above
the junction a narrow drift ridge extends diagonally across the valley, and
at the end of this ridge, on the west side, there is a shallow rock canyon in
which the present stream flows. Another narrow rock canyon begins 14
miles upstream and a half mile farther up there is a wider and deep rock
canyon bordered by drift hills and ridges on both sides. There are, for
several miles above the upper big canyon, no valley flats along the stream.

What appears to be a very good piece of dredging ground, though of
no great extent, has been proved by drilling in the valley flat extending
for 13 miles above the lower rock canyon. The three-quarter mile
stretch below forms part of Boyd’s hay ranch and may also contain some
gold, as may the shallow flats along Lightning creek for some distance
above the junction. The ground on lower Swift was drilled in 1922 for
G. A. Dunlop, to whom the writer is indebted for information regarding
the results. In all, thirty-six holes were put down. All the gold is in the
surface gravels, which average 13 feet in thickness and have a maximum
depth of about 25 feet. Two or three holes were put down.about 75 feet,
but did not reach bedrock, the surface gravels being underlain by hard
silt and boulder clay carrying no gold. Mr. Dunlop estimates that the
drilling proved approximately 4,000,000 yards of ground having an average
value of 31 cents a cubic yard. The surface is fairly heavily timbered in
places, but a large part is grass land. The surface gravels are fairly coarse,
but contain few, if any, large boulders. The gold is concentrated mainly
on the clay, the surface of which is nearly level, and is mostly flaky, but not
very fine, and is easily saved. The property is reached by a good wagon
road turning off from the main highway at Cottonwood. A suction type of
dredge was installed in the autumn of 1924 by Messrs. Kerr and Rowe,
but it is hardly to be expected that favourable results can be obtained
from such a type of dredge, and it is unfortunate that such dredges should
be used when standard types are available. It is probable that a bucket
dredge capable of digging to the required depth and with an estimated cap-
acity of 60,000 yards a month can be placed on the ground for $180,000,
and that actual dredging expenses should not exceed 10 cents a cubic yard.
There is plenty of wood for fuel in the vicinity. The river has a swift current
and at low water averages about 100 feet wide and 1 foot deep. At high
water it is 150 to 200 feet wide and 4 or 5 feet deep.

Some drilling was also done in 1922, about 9 miles up Swift river, by
the Cariboo Exploration Company, an Alberta company organized by H. C.
Foster. Alfred Brown, Barkerville, was in charge. A cross-section of
nine holes was put down, but the results were disappointing as the material
was found to be mostly surface muck underlain by a thick stratum of clay
containing no gold. One hole was put down 100 feet and bedrock was not
reached. A wagon road extending up the east side of the creek leads to the
property.

Peters Creek
Peters creek, the lower part of which is shown on Figure 30, is about

8 miles long and flows northwest into Lightning creek, which it joins about
three-quarters of a mile below Beaver Pass House, where the valley flat of
