Northern Gallatin

We rode up Portal Creek today to check motorized boundaries.  Riding in the meadows and trees in the basin's north of Golden Trout lakes was decent and not caught any wind.  All of the ridge tops appeared to be heavily scoured or wind loaded, depending on aspect and we noted several small wind slabs on the N-NE ridge tops directly above the lake.  They appeared partially filled in so we're likely from a few days ago.  We did not see any recent tracks climbing much above tree line, likely since everything had been so wind affected higher up. 

Saw debris and what looked like a crown line from a natural avalanche that probably happened a day or two ago in palace butte basin on a NE aspect above Arden lake. My best guess is 150ft wide crown, 1-2ft deep?

Low winds/no snow transport when I was up there and the east face had little to no wind effect, probably 16-18in new snow. Saw this slide with about a 8-12in crown and 100ft wide on the north face, didn’t see any other activity aside from some small point releases on really steep east aspects.

Light winds when I was up there with little to no wind effect on the east face. Saw this slide with an 8-12in crown and 100ft wide on the north face, didn’t see any other activity asides from some point releases on really steep east aspects.

From another party: Saw a sizable avalanche on the north east face of Blackmore, likely broke mid storm and was partly filled in already - estimated 20" deep, 100' wide. Had shooting cracks and collapsing while ascending northeast ridge. Hand pits showed planar results on an 8" harder slab beneath all the blower on top.
