Just to the right of the eastern arete of Barrel Buttress at Attermire is a nice vertical flake-line. It's obviously been looked at before because the starting footholds have been brushed. It may even have been climbed but not recorded. It's probably mid-upper 6s. The landing isn't too bad but make sure you pad it properly and don't punt the finishing moves! A belay can be arranged at the top with an assortment of cams, wires and offsets.
