Abstract
Large lakes in the major valleys of the Cordillera of British Columbia integrate in their sedimentary records the sources of sediment in their drainage basins, the processes that delivered the sediments to the lake and deposited them there, and the environmental changes since deglaciation of the lake basin. The eleven lakes described in this study have been assessed by sub-bottom acoustic survey and analysis of core records. Their sedimentary environments include those with high rates of accumulation early in the Holocene but low input presently, those with sustained high rates of accumulation throughout the Holocene, and those with consistently low rates of accumulation despite their situation in regions of high relief and continued glaciation. From these conditions geomorphic and glacial history may be inferred and changing sediment budgets assessed. In addition, the changes in sedimentary processes in the lakes as a response to environmental processes is documented.
