Current Temp: 0 to 5°C Trend:

Comments: Melt freeze crust forming on W-S-E aspects at the surface of varying thickness, decreasing thicknesses with increasing elevation (1 - 10 cm). Surface snow a mixture of wind slabs of varying thickness, mixed with melt freeze crusts of varying supportiveness, and the occasional pocket of soft facets. Somewhat surprised to find a developing Melt/Freeze crust on ENE aspects up to ~10200'. The unseasonably warm temperatures are taking a toll on the snowpack.  Several small debris fields from small R1 to R2s scattered throughout the tree in Red Lake Bowl. Hand shears revealed Wind Slabs 10-20 cm thick, easy moderate planer shears. No cracking or collapsing noted. 3 Stability Tests: CT23 Q3 67cm CT21 Q3 67cm CT24 Q3 67cm. Some melt water observed on the surface of Virginia Lake with a small patch of open water at the lake outlet. The limited parking was quite full with 6 vehicles on arrival.
