Comments
This large slide released about 3 pm Tuesday 1/24, after the slope had been skied many times. This is a popular slope because it is considered to be relatively safe, with a slope angle on the top half of about 34 degrees. The trigger was assumed to be a couple of skiers seen making their way down the ridge after the slide. Note that the crown cuts 4 or 5 previous tracks, and the debris buried more than 10 tracks in the runout. The raised tracks in the bed surface are old tracks put in before the storm.
