Here's a look at the snowpack. You'll notice the new slab laid down since last Wednesday is at least a meter deep and it sits on very weak depth hoar that is elevated a bit more than  a foot off the ground.  Tests showed consistent compression failures within the obvious weak layer....

There was a ton of evidence of natural activity from 1-21-2012 on steep slopes facing most directions at mid-elevations.  Here some pictures of the extensive avalanches....  This one in the area above the Green Gate in the main canyon at around 7400' on a north facing slope was 2 to 3 feet deep, at least 800' wide, and ran around 300 vrt'.
