RAMPART PLACER REGION. 
By L. M. Prindle and F. L. Hess. 
GENERAL STATEMENT. 
Previouswork. — The Rampart, Birch Creek, Fortymile, and Fairbanks 
regions are the four important centers of gold production in that por-I 
tion of the interior of Alaska which is included between the Yukon 
and Xanana rivers. All of these regions have been visited at differ- 1 
ent times by parties from the United States Geological Survey, and 
the results of the work in the Rampart region are presented in reports 
which have been published, or are in course of publication by the Sur-j 
vey a . It was in the course of a geologic reconnaissance trip overland 
from Eagle, by way of Fairbanks to Rampart, during the field season 
of 1904, that the facts which form the basis of this short description 
were ascertained. 
Location. — The Rampart region is in the far western portion of thel 
Yukon-Tanana country, where the distance between the two rivers inj 
a north-south direction is only about 50 miles. It is 140 miles west of 
the Birch Creek region and 80 miles northwest of the Fairbanks region. 
The creeks, which have thus far proved to be of economic importance,! 
are all within -about 30 miles of the Yukon, and belong to the drain- 
age systems of both the Yukon and Tanana rivers. Rampart, the sup-I 
ply point, is situated on the Yukon River, about 70 miles above the 
mouth of the Tanana. 
Communication and transportation facilities. — A government telel 
graph station affords rapid communication with other portions of 
Alaska and the outside world, and supplies are received either by waw 
of St. Michael or Dawson. Those shipped by way of- Dawson reach 
the region earlier in the spring, as the upper river is first open to 
navigation. The first-class passenger rate during the past season f roiia
