Abstract

Up-valley ice retreat approximately 11 000 yr BP resulted in conformable sediments in the main lake indicative of turbidity currents off Lillooet delta which infilled and flattened the underlying surface. Modern glaciolacustrine deposition forms varves which accumulate at a rate of up to 28mm yr "SUP -1" in the north and decline to less than 0.9mm yr "SUP -1" in the south. The occurence of two sediment-runoff regimes, one average and the other extreme leads to distinct differences in varve sedimentology and varve thickness.
