A 20 km diameter crater in the rugged Thaumasia uplands surrounding Solis Lacus contains an unusual filling of smooth material ramped up against the crater rim. While bearing some resemblance to the “pasted on terrain” found associated with many of the gullied craters at similar latitude, this smooth material contains craters. This suggests an age for the material that is older than that of the other examples of crater-lining smooth materials that appear crater-free.
