I was up Pilot Peak on the afternoon of 5/25, and found a nice shell. It probably belongs to the party I passed on the drive in, but it fits me and I could use it. If it's yours, PM me a description and I'll try to get it back to you. If you live in the SLC area, I can probably hand it to you today as I'm passing through.
(Yes, Pilot is technically in Nevada, but I think I remember Utah plates on the cars I passed.)
