Hydrolaccolith

a perennial pingo with an ice nucleus, which forms as a result of an increase in the volume of underground water with freezing under conditions of hydrostatic head in regions containing perennially frozen rocks. Hy-drolaccoliths reach 25-40 m in height and 200 m in width and have the shape of a dome with steep slopes, a gentle hill, or a billow-like rise. The nucleus is covered on top by raised, deformed deposits that are broken by cracks. In the USSR hydrolaccoliths are found primarily in Yakutia.
