No natural avalanches observed. Ski cut triggered D1 slides in everclear, lower moonrise left, round 2 below moonrise, ray, booth, & oswald

Weather: Snowing and blowing all day. Snowing S1 with periods of S2 throughout day but underperformed forecast. Extreme winds throughout day, max gust at ridge 90mph at 2pm! Winds swirling in west wall, upslope and cross slope winds noted on pass through moonrise and thorton’s glade

Snowpack: Wind slab stiffening throughout the day in terrain we travelled. Wind slab not uniformily distributed in travelled areas. Some spots scoured down to firm surface with some noted old tracks. Felt crust below new snow on south aspects. Wind slab developed 1-2ft thick in spots. Sensitivity of wind slab characterized as reactive as we easily triggered small D1 slides with ski cuts.
