Left the car at the Lee Vining Creek Bridge around 7, with temps at 28 degrees, and a strong refreeze. V bowl started to soften slightly, immediately in the sun, and was skinnable without ski crampons at 715. Coke Chute had about 1 cm of corn snow already softened, and would have skied excellently at 9:00, and cramponing conditions were perfect at that time. The snow surface in this chute was very smooth, and consistent. The far right skier's wall, which doesn't see any sun, was still chalky, wintery snow. There were absolutely no winds felt all day, and it felt downright hot on the ascent, and for most of the day in fact.
We dropped into the Third Pillar Chute at 11:15, and the upper section, which was in the sun, had softened, with the skier's left side quite a bit softer. Both the skier's R side of this upper section, and the middle section, which was in the shade, were still good, chalky, wintery snow which was very edgable. Past the dogleg, the chute turns more east, and was fully in the sun. It had softened into very nice corn, with ski pen around 3-5 cm. This continued all the way down the apron and into the moraines, although there were some rough surfaces present.
We hit V Bowl at 11:45, and here at 9000', on a slight NE aspect, ski pen was a little bit more, around 10 cm, but was still on a very supportable base, and made for incredible skiing. The snow didn't become sticky until below about 7800', even just before nooon.
Of note, there were multiple large cracks opening under most of the major chutes on the plateau, and in many other locations as well. We did not notice any natural loose wet activity or rockfall up to the time when we left the area.
