Pingo

 

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 are found both isolated and in groups in regions of widespread frozen rocks. They arise during the upheaval of rocks after local accumulation of ice within them, usually in depressions. 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).
