The Mau Mau*** E4 6a
[Sea of Slate, 2 kb]22m.

Rockfax Description
Seriously strenuous climbing. Start at the dog-leg crack. The crack is easy to the ledge at 10m, after which it is much harder and sustained. Eventually you are forced out onto the wall on the left. © ROCKFAX

UKC Logbook Description
Climb the bow shaped crack. Now the hard bit - step back left to go up the remainder of the crack to finally get to good holds.

Chuffed with this, felt pretty easy having been sport climbing a lot as every hold is a jug. Gear totally bomber, get on it!

Pleased regardless of falling off, first trad fall(s) in a while. Cheers for the belay Louis! Fell off just after the last jug before you move into the pure crack pumped out after placing wire and faffing with useless cam. Second fall after foot slipped laybacking crack pissed off! bomber small cams though! Foot caught a draw so have rope burn war wound to!
bede.west - Lead dog - 12/May/15 with German loui

Made it 2/3rds of the way up before running out of juice and falling. Regardless of the fall the route up to there had been sweet! Can't wait to give it another go!

Awesome line there is loads of gear but very strenuous to place. A few 6a moves & hell'a pumpy climbing, the whole wall is slightly over vertical when you look from the other side......very well protected deserves e4 6a

Out of sequence + pumpy, will return for the lead.

So close! This went well till I barn-doored off the top crack after missing the holds out left. Nasty upside down fall with my leg behind the rope. Pretty sure if I'd seen the holds it would have been in the bag. Gutted. Thanks to the chaps who gave me a tope rope to finish it off!

that was an effort! totally brilliant, bit of an arm-melter peering into the crack to place gear (friends a definite advantage here but you can get great large nuts in). loved the bit where i wanted to stop but couldnt as that would have meant a fall so i had no choice but to continue :) perfect trad!
