A large retrogressive earthflow occurred near Terrace, British Columbia in late December 1993, or early January 1994. Landslide debris extended down Mink Creek one kilometre, and backed water upstream 1200 m. A small channel has incised the spoil and adjacent forest. Post-failure erosion is significant. This paper provides a photographic overview of pre- and post-failure conditions of the earthflow.
Keywords: retrogressive earthflow, landslide, glaciomarine sediment, exposed failure plane, translational sliding, ridge and wedge topography, post-failure erosion, aborted retrogression.
