Snowpack photos: 
More detailed information about the snowpack: 

Pic #1 and 2: Last night's wet precip, followed by warm humidity, followed by cold, clear early morning formed widespread surface crusts and surface hoar. Heat and sun destroyed both quickly, except crusts in shaded aspects (more developed in lower elevations).

Pic #3: This wind loaded NE aspect just shy of Becker Peak's summit was protected from N NE winds and remained loaded, and heated enough by 9am to result in skier triggered roller balls, but no cracking or slab formation.

Pic #4: N aspect of Talking Mountain was scoured by N NE winds, all the way down to old melt freeze forms. Looking N, Ralston, Pyramid, etc appeared similarly scoured. Some slab deposits on S aspects, but only high on ridge - just below ridge on S aspects slabs were very thin and no concern.

I skied N facing trees of Talking down to Upper Echo, ski cutting hard on steep convex rolls in the trees with no results. Surface crust evident from the summit, but didn't really interfere with skiing til lower elevations.
