The Hope Slide
This landslide occurred on January 9, 1965. It is the largest historic slide in western Canada, larger even than the famous Frank slide in Alberta. It buried Highway 3 to a depth of up to 79 m and claimed the lives of four motorists. Failure occurred, without an obvious triggering event, along felsite sheets and joint planes within metavolcanic rocks of the Hozameen Group. Clague and colleagues are studying a variety of mass movements in the Canadian Cordillera to better understand their underlying causes, triggers, and dynamics. (Province of British Columbia photo).
