Snowpack Summary
10 - 15 cm of new snow and moderate variable winds are redistributing new snow into deeper pockets at higher elevations. This sits atop heavily wind-affected surfaces. Roughly 70 to 90 cm can be found at the treeline in White Pass and upwards of 100 cm may exist in wind-loaded areas. The lower snowpack consists of soft, sugary facets and a crust near ground level.
