Wall like structures near Cydonia
The pins show various wall like structures. They may have been used for example to keep water or ice out of an area, or like a dam. Above the two lines going from left to right are dam like structures which will be shown later. The lines shown are degenerate triangles, that is, lines which pass through 3 or more candidate artefacts. These are actual straight lines or within 2 degrees of being straight so these 3 formations would be in a direct line of sight of each other.
