Possibly a new route.
Climbs the arete between Altar Crack and Nonsuch with gear in these routes that can be placed from below the roof. The crack of nonsuch is eliminated completely apart from the first piece of gear. The climbing is really good starting with a font 7a ish crux to pass the roof and then some English 6bish moves to the break.
Not a great headpointing expirience, everything felt terrible on the lead and I felt like I could have fallen of the unprotected move up to the break. Lucky escape!
