90 FAIRBANKS AND RAMPART QUADRANGLES. 
The bed rock of the lower part of the creek is a carbonaceous schis- 
tose grit, which in places becomes slaty. The rather well-rounded 
gravels are of slate, quartzite, and grit, 16 to 18 feet deep, with a cov- 
ering of about 2 feet of muck. The creek is difficult to work on ac- 
count of the live wate ' in the gravels. Through part of their length 
the gravels are frozen on the bottom and thawed for several feet 
above, so that drifts must be timbered throughout. The pay fre- 
quently goes down into the bed rock 3 or 4 feet. 
The gold is generally bright, fine, and somewhat worn. One nug- 
get weighing nearly 4 ounces has been taken out. When poured out 
of a sack a or pan' part of it rolls almost like shot, owing to its rounded 
form. This characteristic is common to a large part of the gold of 
the Rampart region, but particularly so of this area, and is due to its 
crystalline form. The crystal faces are often observable on the pieces. 
The placers of the creek are probably derived largely from reconcen- 
tration of the gold from the gravels of the bench through which the 
creek has cut its course, and in part from the local bed rock. The 
creek is probably more than half worked out. 
RHODE ISLAND CREEK. 
Rhode Island Creek is somewhat larger than Gold Run and heads 
nearer the top of the ridge. Its general conditions of bed rock, 
gravel, etc., are similar to those of Gold Run, below the mouth of 
which Rhode Island Creek flows close against a bluff on its western 
side, while its eastern side rises more gently. 
Considerable work has been done on the creek, but during the sum- 
mer of 1904 no claims were worked. The output is unknown. 
Miners on other creeks are of the opinion that the gravels would pay 
for working if water for hydraulicking could bv obtained. 
SEATTLE CREEK. 
I 
Seattle Creek, although the longer stream, is called a tributary of 
the Rhode Island. It probably carries less than a sluice head of 
water during an ordinary season. The bed rock in the lower part is 
carbonaceous schistose grit. The gravels contain bed-rock fragments, 
quartzite, vein quartz, and carbonaceous slate, and are rather fine. 
They are said to be 8 to 30 feet thick and covered with 1 to 3 feet of 
muck. They are well frozen and have no live water. About $100 was 
taken out in the course of prospecting during the winter of 1903-4. 
The gold is said to be bright, fine, and shotty. Prospecting was to be 
continued during the winter of 1904-5. 
" Known among miners as a " poke."
