Late Glacial and Holocene Environmental Change Inferred from Sedimentary Archives of Kusawa Lake, Boundary Range Mountains, Yukon Territory, Canada
Modern Kusawa Lake (60° 19' 55” N, 136° 4' 48” W, 142 km2) of southwestern Yukon Territory drains a 4290 km2 catchment, 4.7 % of which is glacier covered. Sediment cores show variability both down-lake and within specific sub-basins of the lake. In Regions II -V of Kusawa Lake, sediments a...
