Has anyone done traverse from Sill to Thunderbolt? I always see it written up the other direction. It seems it would be fun to do Swiss Arete then keep going? Thanks!
It's way better that direction IMO. I typically go C2C from Glacier Lodge, up the Swiss Arete, traverse to Tbolt, and downclimb Underhill Couloir (you can also rap it). I have some info/pics here.
