General Observations

Garrett Hallett and I had a fun day in the McCallum Creek area catching the last of the spring corn.  The snow was slush up to ~ 4300' at 9 AM, then hardened above 4300' on north-facing slopes.  South-facing slopes haven't refrozen in a few days and were thawing to a depth of 2-3', north-facing slopes above ~ 4300' were corn for the top 6-12" until around 1 PM, then they began to rapidly thaw.  We skied the pictured line around 1 PM and noted no instabilities up high, but when we started to skin back up the face around 1430 at ~ 5100' the slope was thawed to a depth of 2-3' so we bailed.  

Numerous large natural avalanches noted on all south-facing slopes, a few smaller avalanches on north-facing slopes, predominantly north-east facing slopes.
