Snowpack 50-65 cm fist HST (past 36 hrs) atop 4F suncrust/temp crust (Jan 20). This crust will have different qualities dependent on elevation and aspect. Below Jan 20 there is about 40 cm of 4F atop another 1F suncrust/temp crust (Jan 15). No results with ECT, CT, or skier traffic. Suspect windslabs and cornices in the alpine but no widespread slab or cornice formation at TL on an east asp at 2000 m despite strong west winds. Test profile, Hiyodori 1825 m, SE asp. Open trees.
