Wimberry Trig ... or ... One Out of Four Ain't Bad ~ it's terrible!

If we'd had a proper look at the map, and if I hadn't been dying of exposure, this would have been easy to find.

Fairly soon after the depression where Young John and I made a pit stop, a spur goes off right, SSE from the main wall. Following this for a couple of hundred yards brings you to another wall junction where you turn right (WSW) and the pillar is very soon after, on, or very close to, the wall.

Easy peasy from the comfort of a warm lounge on a Sunday afternoon.

By the way, Mary got home safely.
