I was looking at google maps and decided to zoom in on the Mongolian/China border just to see what was there, and saw this:
This screen shot is at 42.266383, 106.722115
I followed it for a bit and it appears to be a road, or a trench; kind of hard to tell.
Looking further down the map at 46.362984, 117.235606 it appears to be something that was bulldozed:
It appears to span for hundreds, if not thousands, of miles. A quick distance calculator puts these 2 points at 950 KM from each other, so this is one long man made line.
Is this an actual dug out border, or is it something else?
If this is a road, is it possible to travel it's path? If so, where does it start and end?
