"I misread your original post Tom, I thought you were talking about just the begining of the trek down the east side. Internet senior moment (wait, I'm only 44)."
Nah, the senior moment was mine, an increasingly frequent occurrence it seems. I garbled my post pretty badly.
"Finding a way down from the ridge to the south of Upper Lamarck Lake was a real challenge."
From your description, it sounded like a borderline epic. Scrambling over that terrain in the conditions you describe would be pretty hairy, particularly the mixed snow and boulders section. That kind of stuff is a crap shoot half the time, with a very unpleasant downside if things go south on you.
"Usually I look back at challenging times as the best part of an adventure. This won't be one of those times."
When it happens on a solo hike it takes on a whole different feel, IME. Type 3 fun Skurka calls it? Just fun enough to keep us coming back for more ;0)
