Besides avalanche activity, the most notable observation was greater storm totals and a potential poor bond (though isolated) in the recent snow just above the 4/7 interface:
38000ft in a meadow:
height of new snow was 38cm
↓30cm- 1F hard, moist, new snow.
↓38cm 1F hard, melt form, semi-frozen
4500ft, NNW, 36deg slope:
height of new snow was 48cm
↓46cm- easy, clean hand shears where 1F moist storm snow sat on softer dry storm snow just above the 4/7 crust. We also noted that the lower storm snow had a punchy feel underfoot from 4,000-4,500ft. This seemed to coincide w strong-over-week layering that produced easy hand shears.
4900ft, NW 35deg slope
height of new snow was 59cm
hand shears on the 4/7 crust were moderate, planar, but rough. 4/7 crust was still only 10cm thick, more frozen than at 3800ft, but still had underlying weaker melt-forms.
