More detailed information about the avalanche: 

I spottedthe avalanche track on 2/12/12, don't know for sure when it occured.  I did not investigate closely since I was on nordic skis and alone.  This is on the west rim of the lower bowl on Black Crater, just above Black Crater Lake.

More detailed information about the weather: 

The snow was very firm, I barely left tracks with my metal edge skis.  I did not observe any cornices above the avalanche.  It looked like it originated in timber that had been fire killed.

The photo upload didn't work.
