I cannot imagine being able to or wanting to stand inside one of the Spiral Tunnels on “The Big Hill” just east of Field, British Columbia. It just isn't a safe thing to do!! But that is exactly what the photographer for Gowan & Sutton Company must have done to get this beautiful shot of Cathedral Mountain.
The photographer was probably standing at the opening of the top of the Lower Spiral Tunnel in the base of Mt. Stephen. The track continues to curve to the left, which will take it to the Upper Spiral Tunnel built into the base of Cathedral Mountain.
An eastbound train leaving Field climbs a moderate hill, goes through two short, straight tunnels on Mt. Stephen, under the Trans-Canada Highway, across the Kicking Horse River and into the Lower Spiral Tunnel in Mt. Ogden. It spirals to the left up inside the mountain for 891-m and emerges 15-m higher. The train then crosses back over the Kicking Horse River, under the highway a second time and into the 991-m tunnel in Cathedral Mountain. The train spirals to the right, emerging 17-m higher and continues to the top of Kicking Horse Pass.
I have written in my past blogs about this area that straddles British Columbia and Alberta in the Rocky Mountains. See my 2013 entries from February 17th (probably from Cathedral Mountain looking back at Mt. Stephen), March 22nd and April 5th as well as Nov. 8, 2014. I have also written about the publisher/printer on April 12th and August 2nd of 2013 and February 1st of 2014.
