More detailed information about the snowpack: 


-toured from rock creek near iris meadow (~8400')up and down easterly facing gullies (~11,400'). 

NE facing slopes transitional, NNE facing upper elevation still Wintery, ENE to E to ESE micro-corn at mid to upper elevations.  Very Small wet slides from ski turns in steep terrain below 10,000' E facing after noon, that could capture skis and make it hard to move out of.   No natural activity seen today.   East facing gully on McGee had decent sized wet slide debris, un-sure from when but guessing sometime in last few days? (See attached photo).
