Quick Observation
Short afternoon tour in the Northern Flathead Range to enjoy powder on my day off.
We stuck to conservative terrain above 5500' to keep things simple. We skied steep terrain below 5500' and saw only minor sluffing.
There was just enough sun to moisten snow surfaces on southerlies, but not enough to produce more than a couple rollerballs.
A quick pit at 5800' E aspect showed similar weak layer structure (crust sandwich) as what we observed at yesterday's remotely triggered slide in Wahoo, but here the slab was noticeably softer and did not propagate in an extended column test. The slope we tested gets less wind loading than the slope that avalanched on Wahoo.
We could see one recent looking D2 debris pile from a sub-ridge of Nyack, but light was too flat to reliably estimate the flavor or timing of the slide.
