=== Old North Road ===
From an aerial viewpoint, the road system seems to make more sense to Vogh.
Centuries of travel over them have changed the wear pattern, but it looked as if there was a road that went from the southwest to the northeast that included this short section that is presumably the Old North Road. That was probably the North Road in its day. Then the North Road shifted to the west heading north to some unknown destination, while another road came from the southeast and headed northeast. That left the short section as a connecting road which apparently fell into disuse.
The reason for the direction of the roads is that they circumvented two prominent hills--one to the west, one to the east. The one to the west is fairly low but rocky, so it would have been much more work trying to put a road over or through it. The one to the east is higher and steeper, but doesn't appear rocky, so it would have also been more work.
There are no other structures visible in any direction, although Vogh thinks she can see the monastery maybe 70-80 miles to the northwest.
