More detailed information about the snowpack: 

Human-triggered roller balls up to 18 inches in diameter started to occur on E aspects at ~8000 ft. by 10 am. By noon wet snow deeper than boot top height existed on sun-exposed E-SE-S-SW aspects up to 9600 ft. Some small natural loose wet point releases also occurred between 10 am and noon on sun-exposed SW-W aspects below 8500 ft. 

At the upper elevations, widespread evidence of wind scouring existed. On northerly aspects above 8500 ft. in areas sheltered from the E and NE winds, some areas of soft unconsolidated snow still remained.
