| 520 | 3 |a"Following deglaciation about 11–10 ka BP, fine-grained glaciolacustrine sediments, associated with glacial Lake McConnell, were deposited in most of the map area, up to 290 m above sea level (a.s.l.). These sediments overlie buried ice-flow features such as drumlinoids, drumlins, crag-and-tails and fluted bedrock, recording a southwestward ice flow during the last glaciation. A broad discontinuous band of till extends SE-NW in the central part of the map area. Glaciofluvial sediments and some bedrock ridges were reworked into glaciolacustrine beaches throughout the area. These beaches, present at an elevation up to 300–310 m a.s.l., mark the decreasing elevation of the glacial lake over time due to isostatic rebound. In the southwest, only the Horn Plateau, consisting of undifferentiated glacial deposits with colluvium on its slopes, remained above the limit of glaciolacustrine inundation. Minor glaciolacustrine iceberg scours in the southeast and postglacial eolian dunes in the south-central regions trend SE-NW. The fine-grained glaciolacustrine sediments may be overlain by organics and exhibit thermokarst activity"--Abstract. |
