| Comment |
Pingos occur in both the continuous and discontinuous permafrost zones. The term "pingo," a local Inuktitut term used in the Mackenzie Delta, Canada, was applied to relatively large features with heights of 10 m or more and horizontal dimensions of more than 100 m. Most pingos are conical, somewhat asymmetric, and have a circular or oval base and a fissured top that may be cratered. The fissures and craters are the result of rupturing of the soil and vegetation cover during doming due to progressive development of the ice core (see dilation crack). Seasonal frost mounds (e.g., frost blisters), should not be called pingos.
