Quaternary geology of Bluegoose Prairie, Baffin Island, Nunavut
The surficial geology and glacial history of Bluegoose Prairie (NTS 36H/1-8) are described, and the first surficial geology map of the area is presented. Four phases of ice flow occurred in Bluegoose Prairie since the Last Glacial Maximum. Collapse of the Foxe Dome ca. 6.2 - 6.5 14C ka BP initiated...
