South Polar Layered Deposits
ESP_056198_0930 Science Theme:

In spite of the global dust storm that raged across Mars, much of the South Polar region remained relatively clear, so HiRISE acquired a lot of coverage.

The layered deposits are often eroded into spider-like channels, from which dark fans emanate in the springtime as the carbon dioxide frost and ice sublimates (changes from solid to gas).
