Site description The Rasmussen Lowlands are located in the central Canadian Arctic near the base of the Boothia Peninsula. They extend along the eastern side of Rae Strait and the Rasmussen Basin, from the south shore of Netsilik Lake to approximately 45 km north of Arrowsmith Bay. Much of the area is poorly drained, flat lowlands covered with marine silts and sand. The terrain is increasingly rugged in the eastern and northern portions of the Lowlands with the Ross Hills and Wager Highlands bordering the north and east sides respectively. Habitats in the Lowlands vary from partially vegetated, dry tundra with beach ridges and eskers, to richly-vegetated sedge wetlands. Numerous tundra ponds are found throughout the area.
