Summary

Description
English: The image was taken in High Arctic from a helicopter. It shows the crack pattern in permafrost. The image was sent to Professor Hallet for interpretation. Here's what he writes about the image:
"...these look like very fresh contraction crack polygons, probably ice-wedge polygons and mostly likely they developed on beach sediments that were recently under water. Striking patterns!"
