Summary edit

Description	Most gullies in the southern mid-latitudes are on south-facing slopes, which are the coldest and have the most frost in the winter. However, some occur on other slopes. This image shows large gullies on both the pole- and equator-facing slopes. An important puzzle in Mars science is whether or not all of these gullies form in the same geologic eras and by the same processes. NASA/JPL/University of Arizona www.uahirise.org/ESP_058399_1415
