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.
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.
