Whumpfing in Emigrant Gulch Southerly Aspects

Toured in Emigrant Gulch on 03/27/23. The area recieved much less snow during this storm compared to nearby ranges or Northern Absarokas. ~15-20cm of new snow @7000ft, ~20-25cm @9000ft. Dug at quick snowpit on SW aspect of Chico Gully @7000ft. Snow pit was 180cm deep. ECT showed no reactive layers or propagation. However, primary concerns were a sun crust 60cm down in the snowpack and weak surgery snow near the ground. Skinning up the gully we experienced multiple whoomphs in shallower areas near 8000-9000ft and turned around. Skied up to the base of Emigrant Peak SE Gully and experienced several whoomphs at 9000ft likely on the sun crust found in our snowpit. Surface snow was fully saturated at that point. Turned around and enjoyed mellow powder skiing out.
