Surficial geology, Pangnirtung south, Baffin Island, Nunavut / [by] A.S. Dyke. : M183-1/19-2011E-PDF
"In 2009, as part of the GEM project of the Geological Survey of Canada, Cumberland Peninsula east and southeast of the National Park was mapped. Mapping included several aspects of the regional Precambrian geology, as well as the Quaternary geology. Regional till was sampled for sedimentological and geochemical purposes, and moraines and other deposits were sampled for cosmogenic exposure dating. The eastern part of the peninsula is today an area of intensive alpine glaciation and evidently has experienced this style of glaciation throughout the Quaternary. During the last glacial maximum, alpine glaciers thickened to form regional ice divides over the mountains. Ice flow from these divides covered most, possibly all, of the region and supplied ice streams along several fiords. This local ice coalesced with the Laurentide Ice Sheet in Cumberland Sound. Despite possibly repeated glaciation, substantial areas show little or no sign of glacial erosion and retain Tertiary surfaces mantled with block fields and tors"--Abstract.
