Abstract
Glacial Lake Champagne was a major feature of the deglacial landscape of southern Yukon Territory. The sedimentology reflects two major depositional environments; the settling of sediment laden plumes of meltwater from the surrounding ice sheets, and deposits of density underflows. Initial stratigraphic and geomorphic evidence suggests that much of the lake was bounded by active or stagnant ice of the Cordilleran ice sheet. There is one well preserved stand of the lake at 765 m, and a less well preserved stand 725 m above sea level. The 765 m stand of the lake covered approximately 2425 km$/sp2$, and had a maximum depth of at least 159 m. Glacial Lake Champagne occupied the valleys of the Yukon and Dezadeash Rivers and tributaries; and the valleys of the Southern Lakes district. Initial investigation suggests that the lake existed sometime between 12 500 and 10 500 BP, for a period of up to 400 years, based on sediment accumulation.
