This photograph (ESP_048912_1830) was taken by NASA’s Mars Reconnaissance Orbiter (MRO) HiRISE Camera on 01 January 2017.
NASA describes this photograph as “Scoured Floor of Hydraotes Chaos Channel.”
I discovered some more strange geological anomalies in this HiRISE photo, these include what look like dunes with split ends, covered in dark material. The dunes seem to end in either v-shaped and circular walls.
Check out the ‘ship keel-type’ structure as well.
Could these possibly be artificial in some way, perhaps underground entrance-ways or the like designed to look like dunes?
Pure speculation as always, these anomalies look like something unnatural and are not specifically something unnatural.

I downloaded the HiRise B&W Map-Projected JP2 file to view these anomalies.
