We retrieved a cam from the ledge on top of Lonely Challenge this weekend. Looks like it was left to back up a rappel from the tree that was downed. We rappelled from the station just to the right, so we cleaned this cam, which was fairly new.
I remember having read something here (maybe? after a storm? couldn't use the search here, so ...) about someone leaving that cam after finding the tree up/down-turned. Anyway, we'd be happy to return the cam to its owner. It's in good shape. Please describe & post up here, and we'll connect it with you. I'm JSH on Mountain project, you can email me through that site as well.
