This image shows inverted channels within a fan whose origin could be either fluvial (produced by the action of a stream) or alluvial (created by sedimentary deposits).

If the fan is alluvial, then it formed on dry land. If the fan is fluvial, then it could have formed in water, like a delta. Similar fans with inverted channels are found in Eberswalde and Jezero craters, both of which are interpreted as deltas and are considered candidate locations of future rover landing sites.
