Weather Comments
An interesting day of weather, featuring basically every type of weather you could imagine. The skies were primarily broken with a few periods of sun, but at times, they were completely overcast and obscured by heavy snowfall. The winds remained generally light to moderate, with no obvious transport occurring, but there were signs of previous transport and a bit of soft slab/texture along the surface. Snowfall rates were also variable, ranging from light to moderate, with periods of heavy snowfall. Generally, there was consistent snowfall throughout the tour though. Skies seemed to break around 3 PM, and the west and southerly facing aspects received sunlight.

Comments
It was a beautiful day traveling through the mountains. Visibility was intermittent, but there were obvious signs of recent soft slab avalanches and easy sluffing from yesterday. The few periods of sun yesterday, as well as this morning, increased the snow density from generally low to more medium density, giving it a bit more body. Today, while traveling, the upper few inches of snow seemed to be more cohesive than yesterday, making it easy to initiate D1-1.5 soft storm slabs, especially in areas that seemed to have experienced some wind yesterday afternoon. Outside of the wind zone, the snow was still sensitive, and it was easy to initiate fast and far-running sluffs within the new snow. All the avalanches that I witnessed today seemed to fail either within the old snow/new snow interface (those avalanches that were a bit more cohesive and failed larger) or within a density change just a few inches deep.
This afternoon, the sun briefly emerged, greatly increasing the snow density on the solar aspects, which quickly absorbed a lot of heat. I would guess that by tomorrow morning, any new snow instabilities on those aspects will have settled out, but the snow surface may have a thin crust and less enjoyable ski quality.
