Geology of the Region between Proctor and 

 Midway. 



INTRODUCTION. 



The area embraced by the route map from Proctor 

 to Midway [1] lies within the Selkirk and Columbia 

 Mountain systems of the Western Cordillera. The Selkirk 

 system has the Purcell trench (Kootenay lake) as its 

 eastern boundary and the Selkirk valley (Columbia river) 

 as its western. The Columbia system extends westwards 

 from the latter trench to Kettle river [2]. The greater 

 part of the area consists of rugged mountainous country 

 which is often alpine in character, tabular reliefs being 

 isolated and comparatively rare. The main ridges trend 

 in various directions and range in elevation from 5,000 to 

 over 6,000 feet (1,524 to 2,133 m.) with peaks from 1,000 

 to 3,000 feet (304 to 914 m.) higher. 



In the Columbia system west of the subordinate trench 

 occupied in part by Christina lake, the mountains are of
