Notes

Toured into the north Gallatin today and skied on north facing terrain. Saw obvious loading in the new snow up high on the ridge lines, but no recent natural avalanches. We encountered several debris piles that were covered by new snow, probably from a few days ago and likely wind slabs based on the terrain. Skiing, we triggered 3 wind slabs (ss-d1-r1) on a north west facing slope at around 7800’, each ran the entirety of the face. Notably, one of the slabs propagated above the skier and about 20-25 ft to the right. Skiing a north east slope (slightly more sheltered), no signs of instability were observed. We didn’t observe a weak layer underneath the most recent new snow, but we did see a layer of dust and crust deeper in the pack.
