More detailed information about the avalanche

Numerous naturals throughout the area related to rapid warming of snowpack. Most slopes above 40 that had not sluffed naturally would release upon skier entry. Cornice fall also observed. A very good example of spring avy potential and hazard, with wet slides with small crowns rapidly picking up speed and entraining a good deal of heavy wet snow. Small deposits of precip of April 26-27 sitting on old snow surface. Top layers did not appear to refreeze on night of Apr 27 and would release easily on old bed surface. 1 skier caught in wet slide during day and able to eventually ride out, primarily risks related to avalanche path and run out  and what that snow will be moving through and over.
