I finally finished transcribing what I could from the Wedge's summit register. It provides pretty good history between 1989 to present, but many of the pages were in bad shape. it's too bad I don't have the history before 1989. I was able to read about the first 3 ascent parties from the laminated articles included with the summit register. Maybe NMSU archives can shed light on this? I will try to remember to birng the laminated pages back up to the summit on my next trip, along with this transcription.
