a dome-shaped elevation of the earth’s surface, not exceeding 30-40 m in height and 300-400 m in diameter at the base.

Pingos may be seasonal or long-term. Depending on the mechanisms of ice accumulation, these mounds are classified as pingos proper or hydrolaccoliths— pingos with ice cores. Local terms for pingos include bulgunniakh (Yakut) and sede (Nenets).
