Recurring slope lineae (RSL) are anniversary flows on comfortable slopes, and are generally common in executive and eastern Valles Marineris, as seen in this regard by NASA’s Mars Reconnaissance Orbiter (MRO). This picture covers a vast area full of engaging features, though a extended tone closeup prominence some of a RSL.
Here, a RSL are active on east-facing slopes, fluctuating from bouldery turf and terminating on fans. Perhaps a fans themselves built adult over time from a anniversary flows. Part of a fans with abounding RSL are dark, while a downhill apportionment of a fans are bright. The purpose of H2O in RSL activity is a matter of active debate.
