HiRISE | South Polar Residual Ice Cap Erosion (ESP_014141

South Polar Residual Ice Cap Erosion
ESP_014141_0930 Science Theme: Polar Geology

From the original science rationale for this observation, this area shows fast expansion of many different kinds of pits.

It might be possible to see a few meters of change in one year and with the resolution of HiRISE, along with seasonal observations, those changes could be measured accurately. This can also provide information for polar cap growth and decay.
