HiRISE: Crater in the aureole of Pavonis Mons
A crater in the aureole of Pavonis Mons. This is an unusual crater in the Pavonis Mons aureole, possibly a glacial deposit. It appears to have secondaries or textured ejecta (sign of freshness), but is mostly infilled. It also has … Continue reading

HiRISE: Curving pits and ridges
This terrain is unusual for the South Polar region of Mars, with a set of curved ridges of unknown origin. Small pits are present, often concentrated on the ridges, that may have resulted from sublimation of ice. [More at link]
