Location of Observation:
A natural avalanche occurred on the lower snowfield, specifically in the slough pile below Duchess, sometime between 10 am and 1 pm today. Picture attached.
I didn’t observe any other clear signs of avalanche activity around Tucks today. In general, slopes looked smooth and pillowy with obvious slough piles below rock bands. The light was too flat when I traveled in the bowl this afternoon (see below) to be sure there wasn’t new debris there, and skiing out on snow where I expected to find crust cast a further shadow of doubt that there was no new debris.
I traveled on the slope between the run-outs of Lobster Claw and Right Gully around 2pm and found surfaces of primarily wind eroded 1F windslab on top of the freezing rain crust. The snow seemed pretty unreactive on this slope and only exhibited cracking under my skis in areas where it was very thin on top of the crust. Traveling in this same terrain yesterday afternoon, I saw frequent sloughing from the rock bands above resulting in big piles in which 1-2 mm graupel was the primary grain. Today, those graupel piles could still be found in select places, buried by newer wind slab that blew in later in the day and last night.
