Abstract
A landslide of 2.5 million m 3 of sensitive glaciomarine sediments, predominantly silty clays, occurred at Mink Creek near Terrace, British Columbia (54° 27'N, 128° 37'W) sometime between Christmas 1993 and early January 1994. We divide the landslide into 8 zones, distinguished on the basis of morphological characteristics. Using both morphological and sedimentological evidence, we interpret processes of flowing, spreading and sliding, often in succession, as the landslide retrogressed. As the landslide had a travel angle of 2-3 degrees and the slope from the crown to the toe of the rupture surface was 3 degrees, extensive areas of these postglacial sediments may be at hazard from landslides.
