Please disregard the grade on this drawing. I was (I guess) thinking back to the time it took us to find the route while wandering up there during the FA, to finish debating which way we should go and try to get up the easiest way, which wasn't always clear. The route is good, mostly on solid rock and Grade III, with one pitch of 5.9 and 8 easier pitches.
The "Huge Dihedral" in the above drawing is "The Dynamo Hum" route. I only found that out some months after I drew this.
