Pingos are vulnerable to surface disturbance given the considerable amount of ground ice stored within them. Abrupt permafrost thaw processes can cause ice wedges within pingos to melt, which can result in increased pingo collapse and the formation of remnant lakes. Meer weergeven Pingos are intrapermafrost ice-cored hills, 3–70 m (10–230 ft) high and 30–1,000 m (98–3,281 ft) in diameter.
