Tim Blake has climbed the big project wall right of Caff’s recent addition, Mur Margaret in Coed Bryn Engan, opposite the Plas y Brenin complex. See the picture of the adjacent Blair Witch on page 410 in the NWB 3.1 guide.
Betula Wall (7C+) starts standing, hands on two head height sidepulls facing in the same direction. Move up to a flat edge then continue up the centre of the wall.
”It’s around 7C+ish, but could be easier or harder? It turned out pretty good in the end, although a bit spanny to be fair. Will be ace to see what people think of it. It’s got a great balancey move at the top.”, said Tim after the ascent.
