Jelly Roll Arch, 1st Pitch (unknown climber)

Jellyroll Arch 5.8 5b 16 VI- 15 HVS 4c  CA : Tahoe Vicinity : ... : Grouse Slab
This is a must-do route on the east face of Grouse Slab. The route climbs slab underneath the obvious diagonal roof (the Arch), then turns the corner and climbs cracks for another 70 feet or so. Start at the blocks below the terminus of the Arch. Climb up into it and traverse left, protecting in the crack. After turning the corner, belay at the ledge system when rope drag becomes a bitch. A couple 2-3" pieces are helpful. Climb through the crack/roof system abover (its easy 5.5-5.6) and up...[more]   Browse More Classics in CA

The anchors that are just right of The Slash and Unknown (the 5.10 bolted face) are in VERY bad condition! They are handmade, old, rusty and somewhat spinner; additionally, someone has slathered glue all around the base of each but it is totally less than inspiring.

There are other, newer bolts farther right of these, but they do not have rap hangers installed on them.

It is possible to walk off much farther to the right of this wall (i.e. kinda 'next wall over'-ish), and I suggest you do so after cleaning your anchor for the day.

I think the mank should either be replaced or chopped and patched. (I don't own a drill to replace, but I will see what I might be able to do about the latter.) Next time I am out there I also plan to donate two large quicklinks to the "good" bolts at the top so people may rap from them.
