HiRISE: Slope monitoring in Aram Chaos

A previous image, ESP_025954_1835 showed some striking dark downslope flows. Since this is a dark, low-dust setting, these are probably not slope streaks (which form in bright dusty areas). This image can provide us with another look, particularly in order to detect any changes. Recurring slope lineae (RSL) are another type of dark streak seen on Martian slopes and are thought to form from flow of liquid water. [More at link]
