REPORT OF THE CHIEF ASTRONOMER 43 



SESSIONAL PAPER No. 25a 



The Cascade range, the Olympic mountains, the Vancouver range, and the 

 Coast range of British Columbia, with their continuations north and south, 

 compose what may be called the Coastal system. All the ranges east of the 

 Eocky Mountain Trench, with their orographic continuations north and south, 

 constitute the Eocky Mountain system. The Columbia lava plain and the belt 

 of Interior Plateaus form the third and fourth subdivisions. A fifth more or 

 less natural group, yet lacking a name, includes the Bitterroot, Clearwater, 

 Coeur D'Alene, Cabinet, Flathead, Mission, and Purcell ranges, the composite 

 Selkirk system, and the composite Columbia system, with the unnamed system 

 including the Cariboo mountains.
