HiRISE: Melas Chasma valleys
Valleys in Melas Chasma. Caption throwback (2008): The interpretation is that the valleys formed by precipitation in the late Hesperian epoch and the water that formed them collected in the basin to produce a lake where sediment was deposited. This … Continue reading

HiRISE: Slope monitoring
Slope monitoring. The recurring slope lineae (RSL) in this image are large and have high contrast. Most importantly, we see multiple examples of RSL flowing on bedrock, alternating between bedrock and regolith and bedrock and regolith, and regolith only. Do … Continue reading
