This image shows a new impact site originally detected by the Context Camera onboard MRO. The crater is on a dusty slope, which also has several dark slope streaks due to dust avalanches.
A previous impact at another place on Mars triggered a major dust avalanche, but this one did not. This tells us that the dust here is more stable (stronger and/or on a lower slope).
