Thunderbolt Pass

About 2/3 way up Thunderbolt, looking back to Upper Dusy

View into Palisade Basin from Thunderbolt Pass

View of Black Giant Pass

Lake below Black Giant Pass. Steep snowfield leading to lake would require a careful traverse from L-R (S to N) here to avoid it. I didn't have time to try it and/or Black Giant.

Nietzsche Col--corniced, it seemed.

I think this is Wanda Pass area

Out of focus, but looking at Davis Lake Pass.

Looking at the likely start of approach to Darwin Col from Darwin Canyon

View of entire approach to Darwin Col--snowless low point right of the peaklet in the center.

View peering at Darwin Col, the snowless low point to the right of the small peaklet left of center.

Obligatory Lamarck Col shot--boot pack on the left of the snowfield.
