This photograph (ESP_014166_1820) was taken by NASA’s Mars Reconnaissance Orbiter (MRO) HiRISE Camera on 04 August 2009.
NASA describes this photograph as “Possible Layering in Block Material in Hydraotes Chaos.”
I discovered what look like dome-shaped objects, pipes, strange crater/pit anomalies, underground entrances, air-vents, traces of liquid (perhaps water?), vegetation, tracks on the Martian surface, vehicles and craft.
Additional analysis provided by Dawn Hernandez, one of my YouTube Channel Subscribers.
PS: Rotate the ‘disc-like’ craft 180 degrees clockwise to get the true effect. I’ll post a follow-up video in which I look at this anomaly a little closer.
Pure speculation as always, these anomalies look like something unnatural and are not specifically something unnatural.
