Bingo, a pingo!
Of course, none of the pingoes I can
find pictures of have the exact peculiar
shape of the Patomskiy crater. But they
do have similar but varied shapes, of
which this could easily be one more
No evidence of any kind of meteoritic
impact. This is a formation produced
by slow pushing, not instantaneous
impact. All the rocks in evidence in
the photos are broken by cold physical
forces. No evidence of heat; it's not
vulcanism; it's not impact.
That leaves the pingo-theory. From the
raw look of the feature, I would say it
was young compared to other pingoes.
A few hours ago, I'd never heard of a
pingo, and now they seem to be everywhere.
At least, everywhere on the internet.
There are pingoes on the seafloor:
More pingoes here:
Everybody likes to take pingo pictures:
Steps in the cycle:
World's largest pingo?
As for the unique cone-in-a-crater shape,
that could be explained by the growth of
a first large pingo crater-mound with a
collapsed crest (of which there are many examples), followed by a period of
Then, the pingo pump mechanism started up
again on a smaller scale and pushed up the
central mound inside the larger pingo,
with the result we see today. In other
words, a cyclical pingo. It could be driven
by climatic cycles (on the century-length
scale). With an age of about 500 years,
there's been time for a few on-off cycles.

A really strange landform has made the news in Russia and now has appeared
in the Mail Online. Articles with pictures and rather weird speculation
about meteorites and all sorts of other processes that might have created

This is certainly one of the strangest craterwrongs that I have ever seen.

have created this pile of rock?
Does anyone know what is being said about it among Russian geologists and
Whatever, it is, it is quite young.
