Mosquito Creek and Willow River Mine (Figure 19)

Mosquito creek is a short stream heading on the northeast slope of
Island mountain and flowing into Willow river. Near its mouth it is
joined by Red gulch, a larger and longer stream heading near the summit
of the mountain. The two creeks are parallel and only a short distance
apart for about 2,000 feet above Willow river, in which section they flow
in drift-filled valleys. The bedrock valleys of the two creeks join at a point
about 1,500 feet up from the road crossing of the creek, or at the lower end

of the lower hydraulic pit. Lower down the deep channel bends to the
west and enters the deep valley of Willow river somewhere in the vicinity
of Willow River mine, but its exact location near the junction is not known.
A shaft 300 feet above where the road turns up Mosquito creek is known as
the Oliver shaft and is said to be located over the channel and to be 114 feet
deep to bedrock. Its general course is parallel to, and, for the most part,
on the east side of, the road leading up the creek. The channel is apparently
graded to the deep channel of Willow river. A higher bedrock channel
which was first drifted and later hydraulicked out, lies farther east and is
