Comment
Report from control work inbounds 0700-1100. Be advised these results are from an inbounds area where skier compaction and avalanche mitigation are present. These are for informational purposes only and may not reflect backcountry conditions.

8-12" overnight and 4-6" during operation, graupel in the AM then turned to snow by 1100. Lightning was observed in the area between 0600 and 0900. Winds moderate in the morning and died down by the afternoon. The sun even peeked out by 1600, tonights forecast shows more snow.

Many D1-D2 soft slab results crowns 15-30cm. Ran on old snow interface across the N half of the compass.

One wind loaded pocket propagated to a 300ft wide crown, depth was 40cm at the deepest.

This storm left some very reactive storm slabs, propagation was observed across entire start zones. Two natural slides were observed on cross loaded north aspects and one sympathetic slide triggered in an adjacent drainage from a ski cut slide.

No sign of our persistent slab problem.

Inbounds avalanche risk at the resort was rated at moderate for today.
