This photograph (ESP_015978_2190) was taken by NASA’s Mars Reconnaissance Orbiter (MRO) HiRISE Camera on 23 December 2009.
NASA describes this photograph as “Arcadia Region Domes.”
I discovered a vast terrain covered in artifacts that look like stone discs, blocks, megaliths, perhaps even underground entrance-ways and ventilation caps.
If you like archaeology this one is definitely for you.
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.
