Here is Rogers Pass - from Wikipedia :

Rogers Pass (elevation 1,330 m or 4,360 ft) is a high mountain pass through the Selkirk Mountains of British Columbia used by the Canadian Pacific Railway and the Trans-Canada Highway. The pass is a shortcut across the "Big Bend" of the Columbia River from Revelstoke on the west to Donald, near Golden, on the east. The pass was discovered on May 29, 1881, by Major Albert Bowman Rogers, a surveyor working for the Canadian Pacific Railway.

Had not used the Sigma 17-70 (first gen) in quite a while. Still holds up very well IMHO.
