Worsening

Bottom Line

Objective to continue gaining familiarity with snowpack depths and structure in the Northern Elkhorns. Snow heights are highly variable (80-180cm's observed), wind loading and cross loading appear evident on most aspects NW-N-NE-E at tree-line and above. No natural avalanches observed. Blowing snow on ridges assumed given audible winds. Surface snow gains hardness with depth from F-4F and does not appear to behave as a cohesive slab on small test slopes or in hand pits. Limited mechanical testing of the snowpack structure. Anticipate increased hazard due to wind loading throughout the day.
