The Frank Slide in Alberta, Canada
October 28, 2007
The photo above shows a view of the Frank Slide in Alberta, looking southeast along the Crowsnest Highway. This devastating landslide occurred on April 29, 1903 when part of Turtle Mountain collapsed onto the mining town of Frank, Alberta, killing more than 70 people. It traveled more than 2 km (1.2 mi) across the valley, blocking the Oldman River and covering the Canadian Pacific Railway tracks as well as the Crowsnest Highway. The Frank Slide extends approximately 1 km (0.6 mi) in width. An excellent aerial view is available in Google Earth (49.595N, 114.396W). It is amazing how unchanged the appearance is after more than 100 years. Photo taken on July 11, 2007.
