| Abstract | The southwest part of the Conn Lake map sheet lies within the Baffin Uplands Physiographic Region, where bedrock is extensively covered by thick glacial deposits. Some areas exhibiting scour were eroded
by active, warm-based ice for longer periods of time than regions of cold-based ice. A northeastward early Holocene flow is associated with ice in Foxe Basin to the northeast. Four phases of ice flow were recognized. The Last Glacial maximum relates
to phase 1, northeastward, when the region was covered by actively eroding warm-based ice. The second is a north-northeastward flow during the early stages of the Barnes Ice Cap. The next two phases (a later readvance, phase 3, and continued
deglaciation, phase 4) are thought to relate to the proto-Barnes Ice Cap. |
