Crowsnest Pass (sometimes referred to as Crow's Nest Pass, in French passe du Nid-de-Corbeau) is a high mountain pass across the Continental Divide of the Canadian Rockies on the Alberta/British Columbia border. The pass is located in southeast British Columbia and southwest Alberta, and is the southernmost rail and highway route through the Canadian Rockies and the lowest-elevation mountain pass in Canada south of the Yellowhead Pass (1,130 m); the other Major passes, which are higher, being Kicking Horse Pass (1,640 m), Howse Pass (1,530 m) and Vermilion Pass (1,680 m).
Crowsnest Pass comprises a valley running east-west through Crowsnest Ridge. On the Alberta side, the Crowsnest River flows east from Crowsnest Lake, eventually draining into the Oldman River and ultimately reaching Hudson Bay via the Nelson River. Summit Lake on the British Columbia side drains via three intermediary creeks into the Elk River, which feeds into the Kootenay River, and finally into the Columbia River to the Pacific.
Natural resources :
The Crowsnest Pass area on both sides of the provincial boundary is rich in coal deposits, which were quickly developed after completion of the rail line. All the mines on the Alberta side were closed by the end of the 20th century as cheaper and safer open-pit mines opened on the British Columbia side of the pass. Some logging and oil and gas exploitation also occurs in the area, and a sulphur plant has been in operation there for several years. Tourism based on the natural and historical resources of the area remains underdeveloped.
