Triangle

This is almost a perfect looking triangle! It really does look artificially made. I wanted to find better pictures of it, but it is so small which makes it difficult to find or zoom into.


It is located in the Meridiani region. The bottom side is about 70 feet long. The left side is about fifty feet.

Martian House

This looks like a structure of some sort which is located in Acidalia Planitia. I think the resolution is really making it look less natural than it really is. 


The CTX photo doesn't show such symmetry with the object in question. However, it is hard to tell since the resolution of the image doesn't let you zoom in adequately. 

Here's a Close up:

String of Pearls

I don't know quite what to make of this one. You can find it 110 miles east of Perepelkin Crater in the Tempe Terra vicinity. It looks like several little buildings linked together. I've tried to find better quality photos of the specific area but came up empty. After looking at the area with the colorized terrain option selected, I decided that the thing in question might just be the outline of a ridge. There are several ridges that are not visible in the above image. The supposed structure may just be another one of those ridges. But, I still like to imagine that it is a secret colony that NASA never told us about.
