A rhomboidal shaped rockslide covers 30% of a small Clemenceau Icefield Group cirque glacier. By means of remote sensing, airborne photography, climate and seismic data analysis, the extent, timing, possible trigger mechanisms, and rockslide effects on the glacier are discussed. An ML 2·0 seismic event on 14 September2000 represents the rockslide. Shear stress and a combination of rain and snow followed by rapid melt and night-time freezing could have co-triggered the slide. Rockslide characteristics indicate that this rockslide is quite typical for long-runout rockslides on glaciers. Apart from reduced ablation under the rock debris, effects of the rockslide on the glacier were minimal
