Description
This is a great route and certainly one of the best 12ds in the area. Kudos to Mark for bolting it. Climb a slopy steep slab at the far right end of Easter to a big roof with a corner. A hard move gains the corner and another hard move allows an exit over the lip. Look for the hip-scum rest before committing to the last crux.
Note: The previous comment is from the same AC 24.8.164.57 downrating Nevermore. If you had a hard time with Flying Beast and an easier one with Nevermore, maybe one route suits you better. Ease up.
A very bouldery route, basically a 10-move v5 boulder problem with a couple hard clips, but this is nowhere close to 13a. Maybe on the Boulder Canyon scale you could argue 13a, but at Rifle this would clock in at closer to 12c, even without the knee-bars or hip-scums, which I did not find. Similar in difficulty to Nevermore, maybe a titch harder or easier depending on your strengths.
The guidebook I have says 12d/13a. I wonder if the consensus would fall closer to there if it were an option on mountain project. I don't want to labor the point since I feel that a lot of the disagreement over grades is because they are dissected so finely. It's just that 12c/d is an option, but 12d/13a is not.
