Williamson/Tyndall July 1-5, 2011Here are a few selected shots:

First creek crossing. Water up to her knees.

Shepherd Pass

Snow in the gully on the West Face route. Having an ice axe and crampons makes for easy walking. The rock on the right side will go but it's heads up for 3rd class.

The exit off the West Face that leads to the summit plateau on Mt. Williamson.

The North Rib of Tyndall.
