88 FAIRBANKS AND RAMPART QUADRANGLES. 
Glenn Creek, and was first worked in the fall of 1901. The bed rock 
is the same schistose grit, slate, and quartzite. The wash is small 
and snbangnlar, with a few quartzite bowlders and some monzonitic 
rocks from the divide above. The gravel varies in thickness from 2 
feet at the lower side of the claim to 7 or 9 feet in the middle and 5 
feet at the upper end. The gold is bright, rounded, and " shotty," 
Avell distributed through the gravel, and, though it seems strange, the 
nuggets come from near the surface. There are few large pieces of 
gold, the largest nugget taken out weighing a little over 1| ounces. 
A ditch from Rhode Island Creek, 1 mile long and capable of 
carrying 2 sluice heads of water (about 100 miner's inches), has been 
dug; but water is so scarce that it is collected in a pool after being 
used and pumped back to the sluice boxes. For this purpose a 30- 
horsepower boiler, two twinned 4-horsepower upright engines, and 
a 4-inch centrifugal pump are used. Seven men have been employed 
on the claim during the season. 
GLENN CREEK. 
General description. — Glenn Creek is located about 1 mile west of 
Eureka Creek, and flows across the bench gravels. It is about ?> miles 
long, running almost south down the slope from the Baker-Minook 
divide. The valley is shallow and open and probably stands not 
more than 50 feet below the bench. It is practically dry during or- 
dinary summers, but during the wet summer of 1904 it carried water 
sufficient for sluicing. 
Gold was discovered on Glenn Creek by Messrs. Beardsley, Belsea, 
and Dillon in July, 1901. The total production up to the fall of 
1904, according to the most reliable information obtainable, had been 
about $277,500, not including the output of one claim known to have 
produced a considerable amount. During the year ending with the 
fall of 1904 $50,500 is known to have been produced, and this again 
does not include some smaller outputs. Of the 1904 output $11,000 
was obtained by drifting during the winter of 1903-4 and $39,500 
during the summer of 1904. 
The bed rock is similar to that on the other creeks. The alluvial 
deposits are 7 to 9 feet thick and are in large part composed of the 
angular fragments usually found in so weak a stream, with rounded 
material from the bench through which it flows. There are occa- 
sional small bowlders of monzonitic rock from the divide above. 
The quartzite interbedded in the softer slates has given rise to a 
peculiar condition in the gravels of the lower part of the creek. On 
claim No. 1A a section of the gravels shows about a foot of muck, un- 
der which is a discontinuous layer of angular quartzite blocks 8 to 10 
inches thick and 2 feet or more broad, showing no water wearing. 
Under these is a thickness of about 2 feet of washed gravel, and fine
