The Colin Range is located within the Front Ranges of the Rocky Mountains in the Canadian Cordillera. The bedrock geology within the Front Ranges is dominated by thrust sheets that dip steeply to the southwest. The terminology of Cruden and Hu (1996) is used to classify modes of slope movement according to the relationship of the slope to bedrock geology. Photographs from the Bridgland Repeat Photography Project are used to examine modes of slope movement in this study.

Models for sliding and toppling on orthoclinal slopes show that movement of blocks on these slopes is kinematically possible. Several examples of orthoclinal slope movements that occur in the Colin Range are documented, expanding the standard slope movement models to include orthoclinal slopes.

Toppling, exfoliation and sliding are modes of movement that occur on cataclinal slopes within the Colin Range of Jasper National Park. Exfoliation is the most active mode of movement on cataclinal slopes. A rock labyrinth was produced by a large relict slide.

A series of at least 3 debris flow deposits are present within the study area, along Debris Flow Creek, and support the interpretation of complex intermittent debris flows.

The hazard from slope movements is generally low along the west slope of the Colin Range, with the highest hazard being present along Debris Flow Creek and within the steep canyons in adverse weather conditions.
