Upon reaching the crest I traversed below the ridge on a NF aspect and experienced settling of the snowpack. Incidentally, I triggered an avalanche below me roughly 150ft. The avy(s) were roughly 150ft wide by 20" roughly in depth. I had this happen several times along the descent of the ridge staying away from problem areas. The NF snow was fast hero. Yum. It seems as if the north facing lower mid elevations may have snowpack that are more reactive than I thought?! Stayed away and headed East.
