Gullies in Bamberg Crater
Gullies in Bamberg Crater
ESP_024951_2200  Science Theme: Fluvial Processes
This cluster of gullies is on the wall of Bamberg Crater.

The impact crater has an extremely eroded and terraced rim. However, the gullies do not have extensive aprons and overall there appears to be very little material accumulated on the crater floor—unlike many other craters with gullies. This may indicate the gullies are young features.

However, gully formation on Mars is still not completely understood, and more information and observations are needed to improve our interpretation of these features.

This caption is based on the original science rationale.
