lediment in the gravels and no dump boxes were employed. The 
Mats of Moose Creek opposite the mouth of Eureka Creek are covered 
rith a light growth of small spruce and a few small spruce dot the 
teep slopes of the lower Eureka Valley, but lumber for mining pur- 
poses has to be brought from points 6 miles down the Moose Creek 
f alley. 
I Gold was discovered on Eureka Creek in July, 1905. The richness 
bf the gravels justified to a great degree the stampede that followed, 
rhe richest ground that has been discovered was mostly exhausted 
luring July and August, 1906, when there were 50 or more miners on 
|he creek. Wages during the busiest time of the season, when shifts 
Were working night and day, were $1.25 per hour, paid in gold dust 
ralued at $16 per ounce. There was a settlement of considerable 
lize at that time on the flat of Moose Creek just above the mouth of 
Eureka Creek. A restaurant was in operation with rates for board 
done of $4.50 per day, and there were small stores where supplies of 
various kinds were obtainable. About a dozen men were working in 
August, 1906. Various estimates of the output were reported, rang- 
ing from $150,000 to $160,000. 
A small amount of work was done during the summer in the canyon 
of Moose Creek, about 5 miles below Eureka Creek, and some pay was 
reported. 
FRIDAY CREEK. 
Friday Creek is 2\ miles long and carries at the lowest stage about 
half a sluice head of water. The valley is cut to a depth of 1,500 feet 
below the inclosing ridges. The upper part where small streams 
unite is somewhat openly V-shaped; the lower part is very narrow 
and has a grade of over 400 feet to the mile. 
Mining is confined to about a mile of the creek above the point 
where it emerges into the valley of Moose Creek. The bed rock in- 
cludes quartzite schist, carbonaceous schist, greenstone, crystalline 
limestone, and dikes of granite porphyry. The gravels are formed 
mostly of these materials and are from 3 to 6 feet thick. Gold is 
found in 1^ to 2 feet of gravel and about the same thickness of bed 
rock. The gravels are in some places limited to the narrow space of 
12 feet between the bed-rock walls; in others they reach 100 feet in 
width. Both nuggets and fine gold are found. The nuggets range 
in value up to $29. Many of them contain much quartz and are very 
rough, and some are rudely crystallized. Scattered pieces of galena 
several inches in diameter are found in the stream gravels, and one of 
these was assayed for the Survey and found to carry 184.76 ounces of 
silver and 0.20 ounce of gold to the ton. Only six men were working 
on the creek.
