Spring Onion

Today we went to the Onion looking for a wind lip to practice crevasse rescue. We encountered strong winds from the NE. This change in the wind direction is redistributing the snow into a reverse pattern with westerly aspects snow loaded. The alpine now has widespread wind effect on all aspects with lots of hard surfaces. We found all the persistent weak layers in the snowpack, with moderate sudden planar results on the March 5 and hard sudden collapse results on the Mid- Feb Facets.
