Big Trad one this month, and a good appetite whetter for the arrival of Llanberis slate.
Whilst route checking for the aforementioned guide, I happened to spend rather a lot of time and 160m of static on the back wall of Twll Mawr.
This mighty crucible of adventure was pioneered by Joe Brown himself.
Any hoo, here's a snap shot:
My abb rope cuts across the steps of the Razors edge, the grey slab of the true finish is to the far left, and Taith Mawr skips beneath the overhangs in the top right. You may have noticed the overhanging dolerite arete just left of centre..
Here sweeping up the centre of the pic...
The green arrows are bolt belays placed by myself as means of assisting escape or rescue (and preserving my neck while exploring on abb). They rather lend themselves to a 3 pitches and a scramble direct up the back wall. Pitch one would seem possible between Bushmaster and Razors Edge. Pitch two is a 4c formality. Pitch three would be amazing... and appears to have sufficent weakenesses to allow the climbing (if not my belays) to be trad and bolt free.
I have held onto this rather, but the truth is its out of my league. try not to soil it.
