Josenhans, H.W., Barrie, J.V., Conway, C., Patterson, R.T., Mathewes, R.W. and Woodsworth, G.J. 1993. Surficial geology of the Queen Charlotte Basin: evidence of submerged proglacial lakes at 170 m on the continental shelf of western Canada. Current Research, Paper 93-1A: 186?192
A high resolution marine seismic and sampling program in the region was carried out during a 12 day cruise aboard the research vessel CFAV Endeavour. Preliminary results indicate that grounded glaciers deposited sediments in the deep troughs which indent the continental shelf as far west as the shelf break. Offlapping till tongues found in the troughs indicate that ice retreated stepwise from Queen Charlotte Sound at the closed of the last (Late Wisconsinan) glaciation. Detailed studies of submerged shoreline deposits define the volume and frequency of failure of steeply dipping prograde sand and gravel deposits.
