Beautiful day. Clear skies, cold temps, and generally light winds. About as nice as it gets.
No avalanches observed.
Wind: Textured surfaces, drifts, rime, and wind lips were found on nearly all exposed features even below treeline from the recent E winds. This showed potential loading on non-standard aspects (SW-N). Wind slabs were up to 15in (36cm) deep and very firm. Test slopes did not produce cracks.
Upper Spx: The snowpack changed dramatically about 4800ft with much colder and dryier snow on the surface. The height of snow also increased from about 120cm at 4500ft to well over 200cm at 5000ft. While we could find older layers (including rounding surface hoar) in the upper snowpack, tests did not produce any significant results.
In sheltered areas 4-8" (10-20cm) of soft dry powder was present.
At lower elevations a thick and snowmobile supportable surface crust was found throughout the terrain.
