关于这张图
This VIS image shows layering in the south polar cap. The layers are formed over thousands of years of seasonal change, reflecting ice and dust surface deposition. Where the layers appear close to each other are steep trough sides. The steeper the slope, the closer the layers. This image was collected during summer at the south polar cap.
