HiRISE: Young lava flows
This image shows remarkably young lava flows in Elysium Planitia. There are almost no impact craters over this flow, indicating that it is probably only a few million years old—practically an infant in geologic time. [More at link]

THEMIS: A peppering of small craters
THEMIS Image of the Day, April 4, 2018. This field of small dark craters is located in southern Elysium Planitia. The dark appearance against the surrounding lava flows suggests that the craters post-date the lava flows. The small “tails” near … Continue reading
