They are thought to have formed in partially, or totally drained lakes that are underlain by continuous permafrost. The pingos can grow at 2 to 3 centimeters (1 inch) per year. Ibuyk pingo, located in the Pingo National Landmark, is Canada’s tallest pingo and the second tallest pingo in the world. Pingos are threatened by climate change because the warming climate may contribute to pingo melting.
