Pingo National Landmark

Pingo National Landmark is a natural area protecting eight pingos near Tuktoyaktuk. 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. 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.
