Surficial geology, Icebound Lakes (southwest), Baffin Island, Nunavut / [by] E.C. Little, P.J. Holme, and D.E. Kerr.: M183-1/74-2012E-PDF

"In 2002, 2003 and 2005, the Canada-Nunavut Geoscience Office and the Geological Survey of Canada, in collaboration with Polar Continental Shelf Program, Dalhousie University, and University of Alberta, undertook studies of northern Baffin Island to provide an improved understanding of the distribution, nature and chemistry of surficial materials, and glacial history of this region, much of which is extensively covered by thick glacial deposits. Widespread till blanket and hummocky till are common in the map area, and locally meltwater channels dissected the till blanket. Ponding of glacial meltwater resulted in deposition of glaciolacustrine sediments. Some of the smaller preserved glaciers are likely Holocene in age, rather than remnants from the continental ice sheet (Pleistocene), like the Barnes Ice Cap. A complex glacial history resulted from overprinting of both erosive and non-erosive basal thermal regimes at various stages of the deglaciation, as well as overprinting of Last Glacial Maximum (LGM)-related geomorphology"--Abstract.
