| Abstract | In the summer of 1999, a rock avalanche (source volume ca. 180,000 m3) originated from high vertical cliffs surrounding an icefield near Goat Mountain in the Cariboo Mountains, 45 km northwest of
McBride, British Columbia. Field examination of the source area indicated that the initial failure of the steep rock slope was by toppling. The rock mass subsequently disintegrated and flowed out onto the icefield surface. The run-out was 1200 meters
over a total vertical distance of about 200 meters. This event is the first recorded large-scale catastrophic historic landslide to occur in the Pre-Cambrian rocks of the Cariboo Mountains. The Goat Mountain rock avalanche is one of 19 rock
avalanches known to have originated in slopes above glaciers in British Columbia since 1899. |
