| Abstract | The surficial materials in the northwest portion of the Conn Lake map area relate to glaciation and include deglacial landforms and deposits. The upland areas are predominantly exposed bedrock and till.
Some of the till deposits have large permafrost polygons. The valleys are dominated by deglacial features, such as meltwater channels and ice dammed lake deposits. The Isortoq River valley contained a large glacial lake that formed along a retreating
paleo-Barnes Ice Cap margin. The retreating margin formed hundreds of De Geer (or cross-valley) moraines that dominate the geomorphology of the valley. Some small glaciers still exist in the map area; the extent of their recent retreat is evident
from their margins mapped from aerial photographs (ca. 1958) and Landsat imagery (ca. 2000). |
