More detailed information about the avalanche: 

i came up from the lost creek side to look into billy bowl.  very foggy could only see 50 feet.  when i parked my sled on the ridge top and look over i saw a small slide, that i remote triggered moving downhill.  it went 10 yards.  it was 50 yards wide and 1 foot deep.  it broke rougly 5 feet below the cornice line.  no one was in it, no one was in danger at all.  i looked into the bowl and saw it occuring,  i am assuming the vibrations from my sled set it off.  it was snowing and very foggy.
