Whilst out searching the tundra for a tasty evening snack - to be honest I'm not a fan of the chocolate cookies that Allen likes so much - I came across a large area of these strange rock circles and wondered how they got here. Was it the holy site of an ancient tribe? The footprints left by extraterrestrial visitors?
In fact these landforms are completely natural and are produced by the annual cycles of freeze and thaw that take place in the arctic soil, which lift larger rocks to the surface then push them outwards until they gather in rings. I also found these distinct stripes which form by a similar process on shallow slopes.
