Toured between 5000' and 2600' on West and South Aspects. Skied open and treed slopes up to 35+ degrees.

Weather: Clear Skies, Air Temp was -11.4C, ridge top winds were Moderate at 5000, strong higher up. All peaks in view had significant plumes blowing from East to West. Below ridge lines winds were light.
Snowpack: HS at 4850 on West Aspect is 175cm. Surface consists of near surface facets (1mm) and surface hoar (1-2mm, laying down) There is a .5 cm suncrust down 22 cm, Dec 17 is down 72 cm. Dec 17 remains unreactive in ECT's. Compression tests did produce easy results on 1 mm facets down 21 cms (1 cm above suncrust) but were RP-Q3 and this layer was not moving anywhere while skiing. Windslab is hit or miss, more prevalent lower than just below ridge tops. Test slopes produced no results. We did work to avoid bigger, more obvious windslabs, but skied fairly steep slopes at times in open terrain. Some light crusts forming on S. aspects.
Area Description: Immediately South of Stevens Pass
