Quick report

At road level (1400') there was about 4 inches of moist new snow above a melt freeze crust that was well bonded.  Storm total amounts quickly increased with elevation and were 12-16 inches by 3000'.  At 3200' pit results produced easy scores(<10) down 15 cms at a density change within the storm snow and moderate scores (<20) at the interface, no propagation was observed. 3/29 BSH layer at new/old snow interface was easily identifiable and intact and was 2-4mm in size.

At 4500' storm totals increased to 16-20 inches.  Pit results produced similar results to the 3200' pit without propagtion and easy results at density change and moderate results at interface.  3/29 BSH was more pronounced at this elevation at 4-6 mm and very obvious in the pit face.  Lack of propagation in stability tests likely due to minimal cohesion in slab.  Skier triggered avalanches would 've been likely on terrain steeper than 35° especially in areas where storm wind has increased cohesion.

No signs of instability observed

Above 3000 feet 3/29 BSH layer was easily identifiable and intact beneath recent new snow.   Storm snow had minimal cohesion.  Good structure was observed beneath the 3/29 layer.
