dsit in August the dry weather had caused a shortage of water, and 
he mine was not in operation. 
Harrison Creek, with its thawed gravels and dissemination of values, 
vould seem to be worthy of investigation by those looking for ground 
o be mined by steam shovels or dredges. The bed rock, so far as 
:nown, is soft and could be taken up by a dredge. Bowlders appear 
o be absent and the gravels are of a fairly uniform size. As it would 
equire 3 or 4 feet of water to float a dredge it might be necessary to 
ise steam shovels, which would considerably enhance the cost of 
retaliation and operation. 
EAGLE CREEK. 
Gold was discovered on Eagle Creek as early as 1895, but the wave 
if Klondike excitement, which carried many miners out of the 
ountry, retarded its development for several years. Since 1901 
auch profitable mining has been done on this stream. 
Eagle Creek has two forks. The northern, called Miller Fork, does 
Lot appear to carry values, but on the southern, called Mastodon 
^ork, placers have been found. The main stream has a gravel- 
bored flood plain 100 to 400 yards wide, but the tributaries flow 
hrough V-shaped gulches. The bed rock appears to be chiefly 
chist, with an abundance of quartz. 
The alluvium varies from 8 to 20 feet in thickness. Of this 5 to 15 
eet is muck. The gravels are subangular, but are fairly well strati- 
ied and carry considerable clay. The bottom layer is usually made 
ip of 1 or 2 feet of sticky clay. The gravels are not frozen below the 
urface and water circulates through them all winter. The grade of 
he stream is reported to be about 100 feet to the mile. The pay 
itreaks are 4 to 8 feet in thickness and vary from 30 to 80 feet in 
vddth. In some places parallel pay streaks have been mined. Much 
)f the gold is coarse and it has a bright color, with higher value than 
my other of the district. 
Mining has been carried on for about 2 miles along the main creek 
tnd half a mile up Mastodon Fork. A large part of it has been done 
)y drifting in winter. Though the pay streaks are rich, the cost of 
>perating, in view of the fact that all drifts had to be timbered, has 
>een great. It is reported that during the winter of 1905-6 about 25 
nen were at work on the creek. Recently a large group of claims 
las been bought up on this creek, and it is reported that a company 
son templates working them by dredging methods. 
OTHER CREEKS. 
Besides those described above gold has been found on a number of 
:>ther creeks, which have yielded very little. None of these were 
vdsited by the writer except Twelvemile Creek, where no values have
