Hey Eli,
Thanks for posting your TR. A couple of friends and I climbed the Wishbone Arete in 1986. I've attached one photo I converted from a slide image.
Interestingly, while at the southside hut we found a note to an unknown climbing partner telling the person that they were descending but were concerned. We never heard anything more about that but did see helicopters occasionally flying nearby while we were climbing.
I hear the park service is working on the trail system due to prior damages.
