Returning from wolverine cirque we did not anticipate how warm the south aspect, microwave, had become. First hundred feet or so felt light and it quickly became very heavy like skiing in cement. Identified red flag like rollers and we could feel small collapses. Observed a small wet slab on top of lighter snow below it. Quickly cut out best we could to the summer road. Even though it appeared stormy and cloudy all day it seemed to really heat up towards the evening.
