of schists, gneiss, crystalline limestone, some greenstone, serpentine, 
and intrusive hornblende granite. 
Tenderfoot is the only creek that up to the present time (1907) has 
proved productive. Steamers run occasionally from Fairbanks to 
the mouth of Banner Oeek and supplies are thence carried by pack 
train a distance of about 3 miles to Tenderfoot Creek. The creek is 
only about 6 miles long and carries probably not more than 3 to 4 
sluice heads of water. It flows for a part of its course in a narrow 
channel in the muck 15 to 20 feet below the valley floor, which is a 
quarter oi a mile or more wide and has a grade of about 100 feet to 
the mile. There are remnants of a bench of soft deposits in parts of 
the valley just to the west of the creek and about 40 feet above it. 
The valley is filled with deposits ranging, in the prospect holes that 
were being sunk in 1905, from 48 to 120 feet in thickness. The over- 
lying muck is from 36 to 80 feet thick. The gravels are similar to 
those of the Fairbanks region and comprise quartzite schists, mica 
schist, carbonaceous schist, feldspathic schist, and granite. 
RAMPART REGION. 
GENERAL STATEMENTS. 
The Rampart region (see PL II) is about 80 miles northwest of the 
Fairbanks region, and all the creeks of present economic importance 
are within 30 miles of the Yukon and belong to the drainage systems 
of both the Yukon and the Tanana. 
The region has passed through many stages characteristic of the 
life of a placer camp. Some of the creeks were prospected as early 
as 1893 and were 1 active producers by 1896, when the region became 
of equal prominence with the Fortymile and Birch Creek regions. 
Many were attracted by the favorable results, and during the winter 
of 1898-99 the town of Rampart, the suply point of the camp, con- 
tained about 1,500 people. After the preliminary stage of pros- 
pecting and the subsequent excitement of the boom days, with their 
excess of hopes and population, the camp settled down to the labori- 
ous existence of an average producer, influenced from time to time 
by the discoveries of gold in other portions of Alaska and rewarded 
occasionally by discoveries in its own territory. Discoveries have 
recently been made which have contributed to the permanence of the 
camp and illustrated the possibilities still existing in a region which 
has already been under investigation for several years. The intro- 
duction of hydraulic methods, too, entailing the expenditure of con- 
siderable capital, has given further importance to this region. 
The town of Rampart, with a population of a few hundred, is on 
the south bank of the Yukon, 170 miles below Circle and about 70 
miles above the junction with the Tanana, at a point where the
