Crater with Blocky Ejecta
This is a fine example of a crater ~500 m in diameter just north of Eos Chasma, at the eastern end of Valles Marineris at 4.89°S, 322.22°E (see map below). It is clearly very young, because there are large (>10 m dia.) boulders on the rim and crater interior. The crater interior is a simple bowl-shape, but there is a small flat floor which is, presumably, composed of fine rock debris (“talus”) which has fallen from the inner walls.
