This photograph (PSP_006857_2005) was taken by NASA’s Mars Reconnaissance Orbiter (MRO) HiRISE Camera on 12 January 2008.
NASA describes this photograph as “Eastern Nili Fossae.”
I discovered what looks like an artificial structure or object lying at the opening of a hole or crater on the Martian surface.
This anomaly looks totally out of place due to it’s straight, uniform shape.
UPDATE: A Big thank you to Todd, Administrator at WhatsUpInTheSky, who uploaded a RDR PDS version to GigaPan (zoom-in and check out the high level of detail in this photograph). Todd also pointed out other Martian surface anomalies well worth a second look, check it out here.

Could these anomalies be a wall, structure, long pointed object and possibly a city or natural occurring geological features?
