We toured in the June Lake Backcountry today and witnessed a lot of wind transport, but isolated wind drifting.  Wind loaded snow reacted more like Loose Dry avalanches than windslab even though the surface snow was stiffer in places.

Weather Summary

Increasing cloud throughout the day.  Cloud cover was thin initially and then thickened in the afternoon making visibility more challenging at the snow surface.  Wind was present in confined terrain and on ridge lines.   Temperatures were relatively mild and the cloud cover provided for some greenhouse effect.
