Hi,
I came across similar dendritic patterns on Eskimo Lakes ice whilst browsing Google Maps https://www.google.de/maps/@69.509159,-131.539675,971m/data=!3m1!1e3 and have started a discussion on Zooniverse Planet Four terrains https://www.zooniverse.org/projects/mschwamb/planet-four-terrains/talk/9/192678?comment=329756&page=1 . I would appreciate your comments.

Thanks Ray.

I’ve never heard of Zooniverse, but I look forward to checking out your link.

I have a roundish pond on which the melting pattern of several days is a definite trapezoid. In a larger of my ponds, the thawing is also angular. Why? It seems that it might follow the shape of the pond…but aside from that, WHY would these thaw in ANGULAR patterns?

Hi Bev,
That is an interesting observation. I can only guess about the angular nature. If there had been fingers such as those in the top images, the melting from the center may proceed along nearly straight fronts between the fingers. For example, in the top image, there are 7 main fingers, so if the melting fronts were straightish between fingers, the shape would be a 7-sided figure. If two fingers are very close, the fronts may join, making it 6-sided.

Just a guess. I may have seen something like this in the past. Will keep my eyes open for it. Thanks for asking–

Jon
