The standard approach for a day or overnight trip is over Cleaver Col from the N Fork of Lone Pine Creek. The West Side is the easier Class 2-3 approach from the Wallace Creek Drainage (WEST).
My interest is doing some fun ridge-routes this summer. I want to go back and knock of Russell from the east (I'm up for the route I just hit snow last year). Maybe give the East Ridge of Carl Heller a go (with people, of course). Possibly try Lone Pine Peak or Williamson's NE ridge.
As far as Tunnabora goes, If it can be done I'd like to do it. If it hasnt been done I'd sure like to give it a go. Plus, I've not yet done an approach from the George Creek Drainage. If anything I'd like to make some scouting forays into the area. Maybe try Trojan or Barnard...
Mountains by a hairy means...
