There are two separate slides in these images, but both share similar characteristics. Both slopes were heavily windloaded, and were on the north half of the compass. Slab size was similar to other pieces of snow observed today, taking a majority of the snow on the slope down with it. Not a large avalanche in terms of size, but the bench feature and steep transition at the bottom of the slope increase the consequences of being buried. Avalanche stepped down to the ground in places, similar to the trend.
