More detailed information about the snowpack: 

While touring in the East Cabinet Range below McKay Mt. Today, we observed high winds in excess of 30MPH.  Wind slabs were forming and increasing in size and reactivity as we gained elevation.  Gully features were undergoing significant loading as well.  Bullseye data such as collapsing, cracking and very small natural releases were all observed as low as 4,500' in elevation.  Due to the deteriorating conditions we turned around just above 5,000 feet.

A friend who was touring in the West Cabinets near Burnt Mt. today reported that winds were much lower in that area (approx. 5-10 mph) with ECT test results of ECTN19.  No significant slabbing or reactive conditions were observed in this area.
