This photograph (ESP_035036_2225) was taken by NASA’s Mars Reconnaissance Orbiter (MRO) HiRISE Camera on 16 January 2014.
NASA describes this photograph as “Central Peak Ring of Renaudot Crater.”
I discovered what looks like giant structures on Mars, in particular there is a large triangular structure measuring approximately 300 metres per side.
There are various other structures, including several small ‘Stonehenge-type’ structures each measuring approximately 40 metres in diameter.
Many small objects are scattered throughout this photograph. The objects, which may be artificial debris from some kind of technology, measure between 5 metres and 10 metres across.
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.
