A Pingo is a geographical feature found on the tundra formed when the permafrost creates a hill. A Pingo is something studied by scientists, and even more specifically, permafrost scientists. Another name for a pingo is a hydrolaccolith. The pingo is usually a bump shape or cone shape with a core of ice beneath the soil. Pingos apparently even grow taller over time, particularly when they are new. The pingos in the Seward Penninsula often exist on or in the middle of an otherwise flat, wide area of tundra. A Pingo is larger than a hummock/tussock, these being lumps or bumps in the tundra that you step on or over as you walk .
A Pingo is a hill large enough you could walk up it and see the surrounding landscape. Maybe that is what inspired our owner to muse that even animals might like to climb to the top of a pingo. Of course, only in our imagination would a red king crab do this, or possibly a fox or bird.
