AbstractPreliminary investigation of the history of sedimentation in lower Howe Sound fjord near Vancouver, B.C. indicates that no rock slide capable of generating a destructive displacement wave has occurred during the latter half of the Holocene. Possible rock slide run-out deposits were detected along the western margin of Bowen Island. These could date from any time during the Holocene. Investigation of the adjacent slope suggests it is creeping and is not an imminent large rock slide failure.
