THEMIS: Layers in the north polar ice cap
THEMIS Image of the Day, July 22, 2019. Millions of years of alternating seasons have created the north polar cap.
Ice is laid down during the winter and dust coats the ice in summer. The ice/dust cycle creates layers as the cap grows. The layers are revealed on the side of troughs that are eroded down into the cap.
