The second part:
Across a descent bay is Even Chance Buttress with its large central overhang and a holly tree high on its right (a useful landmark). On its right is an unlisted line:
157a Even More Chances HS 4b {U9 4b*}
The right arete of the buttress taking the overhang on the right with a crux move onto the slab above. Finishes more easily.
5m right are twin birch trees in front of a pocketed wall:
U5 3a The left arete is fairly easy to a crux finish.
U8 5a* The wall just right: start off small crimps (no jumps, no arete, no tree) and gain pockets and breaks which are good to the top.
U9 4b The right arete on its left side is a bit precarious high up.
U9 4c* 6m right is a narrowing rib: this starts up the right arete and pulls left onto the face for an easier finish.
U8 4c The slabby facet on the right of the same arete started from crimps.
10m right again is the obvious sharp arete of Chancer, with a scrambling descent corner on its left:
U7 4a 2m right of the corner this problem climbs up the right side of the prominent niche.
157z S {U8 4a} 1m right the reachy wall on good lips and pockets.
158 Chancer VS 4c possible HS 4b {U9 4c**}
The arete on its left is a delightful problem.
U8 4b The arete on its right starting from a block. Harder and more sustained from below and left {U9 4c}.
158b D possible HD 4a {U6}
The crack to the right of the arete has a traditionally hard start. D 3a stepping in from the ledge on the right.
V0 5b* The wall just right of the crack is very fingery and technical (no arete holds).
U9 5a* The same wall using the right arete is only just easier.
U7 4b* Across to the right passing heather climb the wall 1.5m left of its right arete on good holds.
U9 4c* The right arete on its left.
90m right of Chancer (it feels more than twice this distance if you navigate the obstacle course along the base of the crag) is the Secret Buttress area which is well worth a visit. This is a higher section of crag with a band of overhanging capping blocks. Directly above this is where the dry stone wall is built over a low boulder (the easiest descent is on the far right):
158m Crotchless Ron Hills S 4b {U9 4b}
The cracked groove up the middle of the left buttress is climbed on good holds with good protection over a crux overlap.
10 right is the next climb:
158n Heather Mills VD 3c {U7 3c}
On the middle buttress climb the wide jamming crack and wall above.
V0 5a The arete just right on its left.
U6 3c The recess right of the arete has several variations.
U8 4c* The rib front immediately right, from a hard start.
5m right is the main event:
158o Secret Buttress E1 5b* {V2 5b*}
The direct line on the right hand buttress. A technical lower wall leads to a break (runners advised and care with a friable flake). Pull up a tricky groove on sloping holds to a ledge and take the fun overhang above directly.
V0 5b* the arete on its left to the right to join the next route.
158p Don’t Tell HS 4c {U9 4c}
The cracked right arete of the buttress has a boulder problem start from stepping off the block.
V1 5c The groove on the right of the arete from the ground with help from a sneaky sidepull on the left.
90m right again is the last sizable buttress with a prominent capping overhang; it has a good path down its left side. This lies almost directly below the gate at the dog-leg of the wall:
U7 4b* 10m left of the descent is a flame shaped slab. Step delicately up this with no arete holds for hands (a U5 3c cop-out with these).
U6 4a 5m left of the descent is a green slab. Star at the bottom and climb it trending slightly left to retain interest.
U8 4b** Climb the slabby rib on the side of the buttress to jugs and stretch right to pull over the narrowest point of the roof at a niche (good harder roof problems just left).
158t Capped Buttress Direct S 4b {U9 4b}
Start at the left arete of the front face and pull right to gain ledges and finish direct (take care with some potentially friable flakes).
U8 4a 3m right climb the arete and wide crack above: better than it looks.
U7 4a 3m right again is a green slab with a central crack. Climb the right side of the slab with help from the crack.
V0 5a The middle of the right of the slab with no crack or arete holds.
U8 4b The right arete of the slab.
