Between wayside markers, every fifty metres or so there are painted diamonds showing the route. Particularly in dense woodland you become a bit dithery if you can't spot the next one. Your heart rises up when you do.
These routes are maintained by the local rambling group. A good job they do. This diamond was on a pine tree on the ridge between mountains. Very high up, steep drop either side. The diamond and the black outline are in gloss paint. From their regularity I'd say they were stencilled. All this and a light grey undercoat. Three pots of paint, three wet paintbrushes. Must take the whole day.
