Rogers Pass, British Columbia

This is a site description from the 2010 geoNatHaz field school.

Rogers Pass traverses the Selkirk Mountains at 1330 m above sea level, surrounded by summits reaching nearly 3,440 m above sea level. The region receives an average of 10 m annual snowfall, with frequent avalanches. The pass has numerous avalanche structures, and in the winter 105 mm howitzer shells are used to trigger small avalanches before the snow accumulates to dangerous levels. The Rogers Pass segment was completed in 1962, and was the site of the official opening of the Trans-Canada highway [ref]Matthews, B., & Monger, J. .2005. Roadside Geology of Southern British Columbia. Mountain Press Publishing Company. [/ref].

The Selkirk Mountains are thrust- and reverse-faulted into the Selkirk fan, where most rocks west of the pass are are thrust westward with east-dipping surfaces, and those east of the pass are thrust eastward with west-dipping surfaces.
