Is There Martian Mud in Russell Crater?
"A pair of German scientists have examined close-up Martian dune images and found what appears to resemble terrestrial mudflows. On Earth, particularly in alpine and arctic regions, such a debris trail is left behind when fine-grained soil mixes with liquid water from intense rainfall or sudden melting of surface ice and frost."
