Antique Real Photo Postcard. Identified as the Lower Spiral Tunnel, Field, of the Canadian Pacific Railroad. Photo by Byron Harmon #135. Divided back, unused. Condition: This is an original photo postcard, not a copy or reproduction. It is in excellent condition. Comments: (From the Kicking Horse Pass National Historic Site web site.) 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 metres (0.6 miles) and emerges 15 metres (50 feet) higher. The train then crosses back over the Kicking Horse River, under the highway a second time and into the 991 metre (0.6 mile) tunnel in Cathedral Mountain. The train spirals to the right, emerging 17 metres (56 feet) higher and continues to the top of Kicking Horse Pass.
