Red Flags Comment
<p>I could see evidence of fairly extensive natural avalanching involving loose new snow on steep slopes... I could not see any of the big upper elevation bowls or suspect avalanche paths due to poor visibility.</p>

The surface hoar was saturated by rain on Sunday and it became a crumbly crust, a visible stripe in my snowpit wall.

I could see evidence of lots of loose new snow avalanches in steep terrain around Tony Grove Lake. There was some fresh debris from today's natural activity.

Cornices grew hugely in the past couple days, with drifting of heavy snow from sustained southwest winds.

Instability Comment
<p>I did not see any sign of natural avalanches running on a persistent weak layer, but the recent load of wind drifted snow (with 3.5" SWE in the last 4 days), I am concerned that avalanches releasing on buried persistent weak layers from last week's high pressure are likely in some areas and deep hard slab avalanches are possible.</p>

Nice deep powder riding conditions in low angled terrain.  No need to ride on the steeper hills, with plenty of deep snow in the meadows and in sheltered terrain at lower and mid elevations.
