A lot of the photos in the article sure looked like pingos[1], which are common in the Arctic and subarctic, rather than something exotic. Horses before Zebras

A lot of the photos in the article sure looked like pingos[1], which are common in the Arctic and subarctic, rather than something exotic. Horses before Zebras and all that. [1] https://en.wikipedia.org/wiki/Pingo https://en.wikipedia.org/wiki/Pingo

The later photos in the article show very non-pingo large craters with ejecta, though.

Pictures of pingos are shown in the article because some of these craters formed where there were previously pingos. The term is mentioned 6 times in the article.
