Quick report

Cracking
isolated

Below freezing temps overnight helped lock up the snowpack and decrease the avalanche danger. Surface crust found widespread as a result of the moist snow freezing. Observed a few natural avalanches that ran during the storm when the avalanche danger was heightened- failing on the facets above the 12/7 rain crust. 

We kicked out platter sized slab blocks with ski pressure between 6,000 and 6,400 feet but nothing want to move downhill.

Mostly cloudy to overcast skies throughout our travels. Peaks remained visible throughout. Hardly a flick of wind at 6,400 feet. Temperatures were below freezing.

Snowpack

Thick surface crust that was punchy up until about 6,000ft, and then the crust got noticeably softer and thinner higher up in elevation. Surface crust appeared to form from the high-water content in the recent snow freezing up overnight. Where the crust was thicker, we observed platter sized pockets wanting to break away from around our skis, but didn't notice any large shooting cracks of propagation in pit tests. At 5,300ft surface crust was about 5cm, and at 5,800" crust was roughly 2cm. Facets above the 12/7 rain crust were rounding and 1F-. Below the 12/7 rain crust the rounding facets were 4F.
