Report Information
Things are still kinda touchy. Propagating ECT results on depth hoar on a southeast-facing slope above treeline. A natural or remotely triggered avalanche on a southeast-facing slope below treeline.
Batchplant near Eisenhower Tunnel
I parked at the Mountain Residence and took the common skin track up to the basin southeast of Coon Hill. I worked west from here and climbed the ridge up to the Batchplant start zone. I returned to the truck via a similar route.

Unsure if natural or skier/remote triggered. Ran sometime between when I left the truck and my return. |

Snowpack
The snowpack was shallow where I dug in Batchplant--only 69cm deep--but is representative of terrain where the snowpack had consolidated/melted down substantially in this southeast-facing, above treeline start zone prior to the holiday storm. I found a slab sitting on top of basal facets/depth hoar, with ECTP results at the depth hoar. There is a faceting melt-freeze crust in the facets about 5cm above the depth hoar.
Below treeline on southeast-facing slopes I had a couple of rumbling collapses. On my return to the trailhead an avalanche--possibly natural, skier, or remote triggered--had run and covered part of the typical skin track through the area.
