The range is mostly located in Nunavut but extends southeast into the northernmost tip of Labrador and northeastern Quebec. The system is divided into a series of ranges, with mountains reaching heights more than 2,000 m (6,562 ft). The highest of the group is Barbeau Peak on Ellesmere Island at 2,616 m (8,583 ft), which is the highest point in eastern North America. The system is also one of Canada's three mountain systems, the others being the Western Cordillera of Western Canada and the Canadian extension of the Appalachian Mountains into the Gaspe Peninsula and Atlantic Provinces.
The North American Beaver (Castor canadensis) is the only species of beaver in the Americas, native to North America and introduced to South America. Its other vernacular names, including American beaver and Canadian beaver, distinguish this species from the one other extant beaver, Castor fiber, native to Eurasia. ("Canadian beaver" also refers to the subspecies Castor canadensis canadensis).
Pingo National Landmark is a natural area protecting eight pingos near Tuktoyaktuk, Northwest Territories. It is in a coastal region of the Arctic Ocean which contains approximately 1,350 Arctic ice dome hills—approximately one quarter of the world's pingos.
The Landmark comprises an area roughly 16 km2 (6.2 sq mi), just 5 km (3.1 mi) west of Tuktoyaktuk, and includes Ibyuk pingo, Canada's highest (and the world's second-highest), at 49 m (161 ft). The Landmark is managed by Parks Canada under the National Parks Act. Although a nationwide Landmarks program was envisioned at its creation, Pingo remains the country's only National Landmark.
In a region near the Beaufort Sea which is quite flat, pingos dominate the skyline, rising from 5 to 36 m (16 to 118 ft), in various stages of growth and collapse. Ibyuk pingo, the highest, continues to grow about 2 cm (0.79 in) per year, and is estimated to be at least 1,000 years old. Unique to areas of permafrost, pingos have formed here thanks to numerous lakes in the Tuktoyaktuk Peninsula.
Like the Asian species Nelumbo nucifera, the Lotus is an emergent aquatic plant. It grows in lakes and swamps, as well as areas subject to flooding. The roots are anchored in the mud, but the leaves and flowers emerge above the water's surface. The petioles of the leaves may extend as much as 2 m (6.6 ft) and end in a round leaf blade 33–43 cm (13–17 in) in diameter. Mature plants range in height from 0.8 to 1.5 m (2.6 to 4.9 ft).
