There was a lot of activity on Mt. Williamson in the past few days. A party of nine attempted to summit from the South Fork of Bairs Creek, but was turned back at 13,000 feet by freezing cold and high winds. A party of four made an attempt via Shepherd's Pass, but was also rebuffed. Ryan G. and I started up the East Ridge on Sunday. You can judge whether ours was a successful winter ascent of Mt. Williamson.
