What was powder the day before sure changed.  Justin, his brother Jake, and I arrived at the ventilator with cold temps. but a freezing rain/fog coming down.  At first the snow stayed light but at about 4200 feet we climbed into what I am guessing was a warm west flow inversion.  By 5400 feet we decided to turn around as the snow was rapidly turning into mashed potatoes and we thought below it might still be good.  Well, enough precip. had fallen that the snow was rather wet all the way back.  Still turnable and a fun day out anyway.  I am pretty sure that the snow surface is wet enough to form a breakable crust with nighttime low temps.  With a quick compression test at our turnaround we couldn't even get the 10 inches of new over last week's raincrust to go with all 30 taps (32 degree slope).  We simply smashed it down.  The lower snowpack seemed to be bonding nicely as well.
What a difference a day can make indeed. After a great day of making turns in a suprisingly untracked Moonlight bowl Monday, yesterday three of us set the destination of Type Peak. Skinning up we quickly realized the snow went to complete mush. Took a run down the north slopes of Skyline, turned around and called it a day.

Conditions Monday were quite good, with about 6-7 inches of fairly light snow on top of a consolidated snowpack. Although visible in the pit, the rain crust about 18 inches down required quite a bit of force to move.

Here's Mog & Wilki, grading the NW snowpack on Monday in Moonlight -
