Quick report
Early today, the mountain had hard frozen snow, sometimes ice-covered (freezing rain?) below 6800' and 1-3 feet of soft new snow above 6800 . East aspects had 3' of soft wind-transported snow. By afternoon, the snow was wet and soft at all altitudes. Below 6000' it was wet and slushy and boots sunk in knee deep. MOST Importantly: Strong north winds were blowing snow out of the crater onto south aspects all day with enough snow moving to bury deep footprints in 15-30 minutes. This was especially noticeable on the south rim wall just below the rim edge on the steep slopes that used to be the home of the Swift Glacier (east of Monitor Ridge). That snow will be baking in the sun as this warm spell starts. In previous years, big slab avanalches have occurred on this slope, under these conditions, at this time of year. It will, hopefully, settle down before the crowded Mother's Day weekend.
Avalanche
4500'. East aspect, Steep valley wall just west of the route. Looks like it happend 5/7. It was a cornice collapse that triggered a D1 slab that stepped down through several layers of snow. Nobody caught. About 25' wide, 8-12" thick at highest crown. Ran a short distance into the valley floor (see pic). Today (5/8) there were some roller balls and small cornice collapses (4000-5800') but no other avalanches. Of note, the epic rim cornice is sagging and the annual crack has appeared. The crack markes the inner side of the rim (the top of a 1200' cliff). It appeared today when climber fell through a shallow snow bridge exposing 6 feet of a crack a foot wide and 8 feet deep. Rocks on the inner wall of the crater can be seen at the bottom. The crack is well over 20 feet back from the cornice edge. This cornice will be baking in the hot sunshine this weekend.
