Abstract
The postglacial sedimentary record of 59 km "SUP 2" Stave Lake was investigated using 3.5 kHz subbottom profiles and cores from the sediment surface. The acoustic data show a thin cover of acoustically transparent sediment (unit-1) overlying bedrock or glacial sediment on the floor of the lake. Unit-1 is interpreted as resulting from deposition in a relatively quiet lacustrine or marine environment following retreat of Vashon glacier about 13 ka ago. Unit-2 is ascribed to deposits of sediment in runoff to Stave Lake from the Sumas ice sheet in the Fraser Valley and connecting valleys to the Stave Basin. Following the retreat of the Sumas ice about 11 ka ago, deposition of unit-3 resulted almost entirely from sediment input from Stave River entering the north end of the lake. The rates of sediment yield calculated from accumulation in Stave Lake are 4.5 X 10 "SUP 5" kg.km "SUP -2" a "SUP -1" (modern) and less than 2 X 10 "SUP 5" kg.km "SUP -2" .a "SUP -1" (averaged over the Holocene).
