Looking for a parallel road above Mitchellslacks

 

Parallel roads are the old shorelines of glacial lakes, relics of the Ice Ages. I've never been to Glen Roy so I was excited to read in Ronald Turnbull's Cicerone guide to the Southern Uplands that one was visible from the route up Queensberry. It does have a rough road along it - the vehicles of a shoot are just visible - but it is a natural feature. He points out that there are more streams coming down the hillside to that line than there are continuing down the hillside below the line - a sign of an ancient boundary.
