I hiked Tyndall on Saturday.

Warm conditions softened the snow considerably and there were a lot of small point release avalanches.

There was a snowstorm Saturday night, a few inches fell. Due to the fresh snow, conditions weren't good for Williamson and the other campers in the area were bailing on their attempt as well.
