It's not an arctic version of BINGO! A pingo is a soil covered hill or dome with an ice core. Pingos are about 30 to 50 m (98 to 164 ft) high and up to 400 m (1,312 ft) in diameter and can create striking landscapes in some Arctic regions. They are believed to form as a result of the freezing and upward expansion of water found in subsurface soil as well as by the rising and freezing of water trapped underneath or within the permafrost.
