Some limestone esoterica... A few months ago Dawid and I climbed a 15 move roof line in Odin Cave near Castleton. It crosses a completely horizontal groove, with all manner of unlikely techniques and bizarre moves: underclinging grit like slopers, a desperate toehook lunge, a drop-down on a backhand pocket... I had so much fun climbing this! We've been keeping it quiet for ages in the hope that we'd get round to finishing off some of the other lines, but it hasn't happened, so might as well share...
The Dark Room, 8A
Sitstart at the left end of the obvious groove at the back of the cave. Follow this rightwards to finish matched on the jug. You could top out up the slimey chimney if you wanted.
There's also a 7A+ that climbs into the same jug from an obvious sitter at the back. If you are making a visit, probably best to wait for a dry spell. A tarp is always useful to cover the wet bit on the floor. To reach the cave, drive to Winnat's pass and turn right just before the pass. The cave is at the end of the road, on the left.
