Glide avalanche released from the upper portion of the slope & ran over an area where a previous glide avalanche had occurred 2 weeks ago. Rapid warmth & the presence of wet loose surface conditions may have contributed to this event. The pocket of slab broke & gathered mass as it slid to the bottom of the slope over 1000' below.

Wet loose surface avalanches. Deep ski & boot penetration. Frequent glide avalanches. Cornices shedding
+40F with winds 3-5 gusting to 10mph. Mostly sunny
~1" new snow at treeline which was wind battered & sun effected. Below 2400' a deep isothermic snowpack exists with boot penetration +2.5' in areas. Above 2400' a finger hard 1cm thick unsupportable crust exists, just enough to keep you sliding well on top.
Superficial hand pits & surface clues indicate freezing occurred above 2400' & no overnight freezing below that mark. An upside-down ski pole will easily go through the snowpack below treeline. Other than all the visible instabilities there was good snowboarding to be had, although the dog was wallowing & very exhausted.
