Travelled up out of Pine Creek to the central Tungstar Bowl's main chute to see if I could find any concerning windslabs.  Short answer: only a couple isolated areas with 2-3" thick hard pencil-plus snow ontop of fist hard snow that failed easily after isolation on north facing approach slopes at 10,600' (see attached video).  This made me keep vigilant as I climbed the steeper chute, keeping my eyes out for similar structure and potentialy thicker slab.  While the snow in the chute was variable from patches of very firm scoured windboard to boot-top soft snow, I couldn't find anything concerning.  Consitently found hand pit results similar to the second video attached (well bonded snow with no shears).  Some very manageable surface sloughing was all there was on the ski down.  

A few areas on solar aspects had some small loose-wet rollerball activity from Sunday with few couds, but nothing concerning today.  

-12,300', SE aspect at 2:30pm had top 10cm of snow slightly moist ontop of stout firm frozen crust.  Air temp -5°C.  

-8,500', 3:15pm: air temp 3°C.  

Snow in the sheltered chute skied well despite some variability, but everything else was quite challenging varying mostly from breakable to firm windboard with some areas of dust on crust.  No ankle or knee tweeks on the way out thankfully.  Hiked in tennis shoes on trail (with some stretches still covered in snow) to steep entry gully into the Tungstar bowl, good crampon conditions up steep drainage despite some thin hollow sections (wouldn't want to be booting up in much warmer conditions - see pic).  Ski crampons were quite useful for much of the ascent after that.  Survival side-slipping and stepping on the way down the steep drainage.

More detailed information about the weather: 

Thin high cloud cover allowed a good bit of sunshine thru for most of the day, but limited it's intensity.  Cool below freezing temps at mid and upper elevations at mid-day, but in the sunshine it felt quite warm.  Calm winds except at the very top of ridge at 12,300 where a light south breeze was blowing, but not moving any snow.
