Abstract The Frank Slide is at the east end of the Municipality of Crowsnest Pass, southwestern Alberta, lying within the valley of the Crowsnest River in the Front Ranges of the Canadian Rockies. Alberta 3 crosses the slide and, immediately north of the slide debris at the bridge over Gold Creek, an access road leaves the highway for a new Orientation Center, 1.1 mi (1.7 km) to the northeast (Fig. 1). The center, an excellent starting point for a tour of the slide, provides a superb view of Turtle Mountain, the slide scar on its eastern flank, and the immense pile of shattered limestone on the valley floor (Fig. 2).
