Cloud cover increased and lowered throughout the day and winds picked up significantly and were transporting a lot of snow. Ground visibility due to blowing snow was poor.
We generally traveled on solar aspects, S-W, from 5400'-10K. Below 7k was a mix of thick breakable melt-freeze grading to recycled powder depending on how much direct sun a slope received - Pan Pt. had a very thick crust, but the flats below were softer. The Muir snowfield was a mix of soft wind blown snow, pockets of breakable wind skins, and exposed blue ice.
