22-23

The Bozeman snow ranger crew rode on Buck Ridge today and did not see any recent avalanche activity.  There was 4-6 inches of new settled new snow over very firm older snow, so the riding was somewhat deceptive (not the easiest).  We rode out to Bear creek and the wilderness boundary there and noted that the new snow had been blown around quite a bit on the ridge tops.  Some folks had done some pretty aggressive riding in the upper portion of McAtee Basin but didnt trigger anything.  We also rode down Muddy Basin a ways and found much better riding there; less sled traffic and likely better wind shelter than buck ridge proper.  We peeked into the Yellow Mules and did not see any recent activity there, either.  Hope that info is helpful!

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.

AAI Pro 1 again. Tour to top of ramp and wolverine bowl. Weather was cold all day with increasing west winds. Wind transport increasing during the day as well. Aside from size 1 dry loose in steep terrain and a small wind slab on a high elevation SE aspect (SS-N-R2D1-I), we observed few signs of instability. Variable wind directions (E to W) have stripped and re-loaded various slopes and have not led to significant slab development. Significant scouring present on E and NE aspects in Wolverine from the wind yesterday. We dug 7 test pits on the E aspect, which was currently being loaded, and got no results in the recent snow. One student did get ECTP26 down 90 cm on FCs but he was in a shallow location not representative of the general area. Perhaps a sign that in thin areas the PWL is still capable of producing avalanches but overall the snowpack seems deep and strong.

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.
