Observations from Far NE ridge of Mt. Lola.

We went to the Far NE ridge of Mt. Lola today for a mix of snowmobile and ski based observations. The Dec 11 PWL facets are prominent in this area. We observed limited evidence of slow strength gains. We experienced fewer snowpack collapses today (less than 5) and propagation seemed not to extend more than about 3 feet away from us. Snowmobile track would periodically drop down into the facet layer but was also fairly easy to keep on top of the upper snowpack. Stepping off of equipment, foot penetration went right down into the facets.

Snowpit data gathered in open below treeline terrain gave mixed results on the Dec 11 PWL.  However, propagation along this weak layer remains possible.

Along the ridgetop in near treeline terrain, minor wind slab development had occurred from SW winds. Light blowing snow was observed late morning. This drifting snow ceased by midday as winds decreased slightly. Small pockets of wind slab existed near treeline with some minor skier triggered cracking observed.
