Last week I walked along Harlech Road, on the north slope of High West. I'd gone to take a photo of the war department boundary stone #18, which lies just a few feet down the slope below the road.
I'd looked carefully along the road before, but only ever found this one stone. On this day though, I happened to be walking the opposite direction from usual - up instead of down. Maybe that's why I spotted stone #11, a little further up the path, but on the slope above the road.
