Check. This. Out. The HiRISE camera caught avalanches in action near the north pole of Mars. It’s spring right now, and the ice is thawing. That means that the polar layers are becoming unstable as the ice sublimates away, which leads to avalanches. What is awesome is that in this image, they caught more than one avalanche happening at the same time, implying that these things are super-common!
