Comments
This slide was triggered while descending the slope along a sub-ridge in a shallow part of the slope. It averaged 12-18" deep and failed on surface hoar. Many slopes with similar aspect and elevation were ridden without incident today, which verifies the pockety nature of surface hoar.
Comments
The soft slab was a combination of fist snow on top with 4f snow underneath. This surface hoar developed on 2/16/10 and is now buried about 16-20" deep.
