PINCERS OF THE RAMPART REGION. 93 
came from the sluice boxes contained 6.38 ounces of silver and 2.41 
ounces of impurities, and had a value of $15.17 per ounce. Each assay 
gives about 20 per cent as the silver content of the gold. 
Water for sluicing is brought from Eureka and Chicago creeks, but 
the supply is scanty. The probabilities are that the production of gold 
upon Thanksgiving Creek will increase considerably, but as in most 
of the diggings of the Baker Creek group more water is needed. 
HUTLINA CREEK. 
Hutlina Creek is a large tributary of Baker Creek, several miles 
southeast of, and having a generally parallel course to Pioneer Creek. 
As seen from Glenn Creek its valley and that of its principal tribu- 
tary are shaped similarly to those of Pioneer and Eureka creeks, and 
prospectors confirm this impression. A stampede to the Hutlina oc- 
curred in 1902, and it is reported that colors and occasionally good 
prospects were found, but live water in the gravels prevented their 
being worked without machinery. The bed rock is said to be similar 
to that of Pioneer Creek. At the time the Geological Survey party 
left Rampart, September 20, 1904, several prospectors were going 
into the valley with tools and provisions to prospect the benches dur- 
ing the winter. 
PATTERSON CREEK.' 1 
The following notes, collected from various sources, are considered 
reliable, though the writer was not able to verify them by personal 
observation. 
Patterson Creek is a tributary of the lower Tanana, some of whose 
tributaries rise in Rough Top Mountain and others in a broad, flat 
divide between the Tanana and Left Fork of Baker Creek. Gold 
was discovered on Patterson Creek at the mouth of Easy Money and 
Sullivan creeks, which join to form the main valley. The scene of 
the discovery lies close to the trail from Hot Springs to the mouth 
of the Tanana. The gravels are from 35 to TO feet deep, and the 
bed rock is chiefly slate. The gold is similar in character to that 
found on Glenn Creek. Although there was no actual mining in this 
district, in 1907, sufficient gold had been found to warrant careful 
prospecting. This occurrence appears to be similar to the placers 
of the Glenn Creek region. Its position and character suggest that 
the Patterson Creek deposit may represent a southwestern extension 
of the Glenn Creek district. 
WATER FOR HYDRAULICKING. 
A large part of the gravels of the creeks and benches of the Baker 
Creek area, while they will not pay for shoveling in. would probably 
pay for working if water for hydraulicking could be obtained at a 
a By Alfred H. Brooks.
