The peak east of Glacier Pass is Peak 11700+. I was on that peak (just west of Sawtooth Pass). I could be wrong, but my memory of looking at Empire Mtn. from Pk 11,700+ indicates that this is indeed Empire. No big thing, but it caught my eye.
Now that I think about it... When I did Pk 11,700+, it was from Sawtooth Pass, so I could be wrong here, and am looking that peak from the west... oh well, who knows? My claimb was about 25 years ago.
