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, at 49 m (161 ft). The Landmark is managed by Parks Canada within the national park system system, 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.Besides pingos, the Landmark contains an excellent example of massive ice. One section of the frozen groundwater, part of an eroded hillside by the sea, is over 500 m (1,600 ft) long, and 10 m (33 ft) high. Other less visible ice beds in the region are over 40 m (130 ft) thick. This type of ice is found in permafrost, and can be thousands of years old.
