106 ALASKAN MINERAL RESOURCES IN 1904. [bull. 259. 
In the winter transportation to the creeks is either by dog or horse 
sleds, the rates varying from 2 to 6 cents a pound according to the 
distance. In the summer pack horses are used, and the rates vary 
from 4 to 15 cents a pound. The summer trails are generally bad and 
remain in about tbe same condition from year to year. 
Mining activity. —The region has produced gold continuously since 
L896. New discoveries have been made from time to time, and the 
discovery of good pa} T in a new locality during the past } 7 ear shows! 
the possibilities even in a district that was believed to be thorougniy 
prospected. During the past season prospecting was being actively 
carried on throughout the region, and men were found investigating 
creeks, where in 1902 nothing was being done. Hydraulic methods 
have been introduced, and the last steamers up the river brought many 
tons of hydraulic pipe and other supplies for several plants which 
are in process of installation. The production of the region during 
the last year has been about $235,000, and the total production up to 
the present time is probably over $1,000,000. 
GEOGRAPHIC SKETCH. 
RELIEF. 
The Rampart region is one of rather strong relief, ranging from 
4,640 feet above sea level at the summit of Wolverine Mountain to 
somewhat over 400 feet on the Yukon at Rampart. On the northern 
and southern sides of the Yukon-Tanana country there is generally 
observable a difference in topographic expression, which in the nar4 
rower space between the two rivers is brought into sharper contrast. 
The divide between the Yukon and the Tanana rivers is about 25 miles 
south of the Yukon. The area north of the divide is rough, and the 
high peaks of Lynx and Wolverine mountains are the most prominent 
features. Steep-sided ridges separate the many deep, narrow canyon^ 
whose similarity has frequently led to confusion and justifies the name 
"Troublesome Country," applied to a portion of the region. South 
of the divide long, gradually sloping ridges separate the more open 
valleys and merge finally into the extensive flat of Baker Creek, a 
tributary of the Tanana. 
An area about 24 miles long, with an extreme width of 15 miles, 
includes all the localities where work is now in progress. The south- 
ern portion of this area is cut diagonally by the divide which, with a 
minimum altitude of about 2,000 feet, extends in a northeast-southwest 
direction and separates the headwaters of the two drainage system* 
DRAINAGE. 
The drainage of the region is shown in the accompanying sketch 
map, which has been prepared by Mr. Hess from data collected at
