OUTLINE MAP SHOWING ALASKA-CANADA BOUNDARY LINL 



The heavy black line along the 141st meridian denotes the completed part of the bound- 

 ary. The coast boundary, ending at Mount Saint Elias, is practically completed. The dotted 

 lines show the routes followed from Whitehorse when going to the field. 



"The maps, when published, will be among the finest of their kind in the world; besides 

 showing the differences of elevation and drainage, they will also differentiate, by means of 

 symbols, between the various growths of timber and show their density. The character of 

 the country, whether of swamp or tundra, will also be shown. A line of precise_ levels, run 

 from tidewater to a point on the boundary, furnishes the initial elevation for mapping, whence 

 elevations for triangulation are taken and extended trigonometrically both north and south."
