Cloud ceiling was about at 5800ft all day, keeping views limited. About 6 inches of low density snow fell last night, and it was minimally wind-affected where we traveled, aside from minor cornice re-distributions along ridgelines. Occasional light SW wind was noted. Light snow began around noon.
The Excelsior Basin was extensively ridden and no signs of old avalanches were seen, and we did not see or trigger any new avalanches.
We heard one report of a large natural avalanche on the neighboring Bearpaw Mtn, failing in a rocky chute near the top of the mountain on a northeast aspect, which probably occurred Saturday.
We found a right-side-up snowpack with good riding in the Excelsior basin at 5100-5500ft. The March 8 crust (or harder snow layer) was noticeable about 2 feet down in some spots near the bottom of the basin.
In pit tests we found several storm snow layers failing on moderate compression taps, and failing but not propagating in an extended column test, in the top foot of snow.
Snow heights were around 400cm in the basin. At 3500ft the snow was a variable 150cm in clearings, but by that elevation a lot of the snow was melted out beneath trees. About 3000ft is where the snowline was from the previous night. In the afternoon, snowmelt which occurred during the day was very noticeable from that elevation down.
