OK, Mike - although you're clearly pushing hard on the 'artificial' angle (as usual) even though you ask US to decide:
My decision is that this is nothing more than natural geologic features photographed and image-enhanced in a way to make them appear to be interpreted
as something artificial. Which I believe them NOT to be.
Like the glass worms, pyramids, 'cities', bridges, tunnels, and other imaginary synthetics, this also falls into the category of "nothing there" -
just a tiny piece of landscape in a vast, desolate, dead planet in which some geologic features happen to have some geometry that bears a slight
resemblance to things humans may be familiar with.
Also - there is no corroborative info - hard to decide anything based on an image that could have been altered, PS-ed, CGI-embellished, etc. As we
all know, fakes abound. And attention-seekers attempting to grandstand abound as well. Interesting stuff - but no proof here by any stretch...
Though, thanks for posting again Mike - your alarmist pre-conceived images are entertaining at least, and very worthy of discussion. Good job.
