"The map area on the flank of North Shore Mountains is incised by three glacially-widened valleys. Glacial cycles caused sporadic erosion and deposition of sediments mantling the slopes. Most surficial deposits are from the last glaciation; however, some exposures and seismic data show older sediments, especially within buried valleys. During deglaciation, the sea level reached 200 m and meltwater issuing from the valleys formed glaciomarine deltas. Falling postglacial sea levels caused the deltas to be incised. Modern rivers mainly re-mobilize the older sediments. Other contemporary deposits include alluvial fans and debris flows on steep mountain slopes, and landslides on the flanks of incised valleys. Anthropogenic alterations of the landscape include land reclamation along the waterfront and infilling of valleys and slopes to provide level building sites and to mitigate the affects of flooding from mountain streams"--Abstract.
