The Dubawnt Lake palaeo-ice stream
In this article, the authors report outstanding evidence for a major terrestrial ice stream which operated in the Keewatin Sector of the former North American (Laurentide) Ice Sheet, north of Dubawnt Lake, Nunavut Territory, Arctic Canada. They present a clear description of the linear features left behind by the ice-stream and propose a depositional mechanism. The Dubawnt paleo-ice stream is the only known possible analogue for the process that shaped the Hondsrug and its adjacent ridges during the Saale ice age.
