As c b said, It was very warm yesterday. I only spied them from the lakes and wasn't on snow, but all 3 appeared to be solid lines, with a good sized bergschrund in rightmost couloir. I'd never seen them in person. Impressive lines. The crappy haze in this pic from yesterday is smoke. By afternoon it was so thick you could just barely make out Conness at the end of the valley. Crazy.
