Snowpack Observations


A tour up Green Butte Ridge saw a mixed bag of conditions.  New snow totals observed ranged from 2-4in (5-10cm) on the way up to 7700 feet. Many small wind drifts were encountered along the way. These drifts varied from 24in-39in (60cm to 100cm).  Snow consisted of a mix of soft wind transported and new snow for the first 4-6in (10-15cm). This layer was F hardness and sat atop a 2 in (5cm) 4F hardness layer of fragmented particles (DF) and rounded grains (RG).  These soft slabs were stubborn to trigger and only non-planar fracturs were observed. A quick column test showed little concerning reactivity (CTM10Q3 and CTH23Q3). No large slabs were encountered. The ski down had fast conditions. You could feel a rain crust under the new snow on some aspects.
