Artificial Constructions?

'Washed out' Building or Bridge Structure?

MOC Images - MSSS/MOC Image M18-00318

Located near the Martian north polar rim, this support structure for a possible bridge is found in what appears to have been a very large wash-out, or was once the mouth of a river bed. This structure spans a distance greater than 1.6 miles (2.6 km).


Context Image Map

Notice the small dark spots on the bridge. Possible moss or plant-type growth perhaps? MOC's narrow-angle image covers more than 57 square miles (92.55 square km) of this area, but the dark spots appear only on the 'bridge' and within the geometric shaped square constructions.
