This announcement came out a couple months ago about the discovery of lobate flows on Mars likely being the result of water and ice transport, but I just stumbled across it.
It's another pretty compelling piece of geomorphic evidence that's quickly building a new understanding of Martian history.
The work was carried out by the Planetary Science Institute in Tucson, using images from the THEMIS camera run by ASU.
