Quick Observation
Returned to the Snowslip weather station for additional maintenance today. Toured up the Shed 7 west path and continued through the prominent cornice feature, and onto the south summit of Snowslip to the weather station location. Descended the Shed 7 West path.
Skies were overcast and air temperatures were in the mid-20s °F at the Canyon floor and mid-teens °F above 6000 feet throughout the day. Light snowfall for most of the day with occasional moderate snowfall rates. Moderate to strong west winds were actively loading easterly aspects at elevations above 6000 feet all day.
New snow accumulation of 4-6 inches since yesterday.
Heavy windloading on easterly aspects above 6000 feet elevation.
Cornice growth has continued over the past 24 hours. Our route cut through the Shed 7 West cornice was completely filled back in today.
A large cornice has also formed at the top of the Infinity avalanche path.
Saw one very small wind slab had released below the cornice in the Shed 7 West path.
Pieces of the Shed 7 West cornice have been breaking off and sending small chunks of debris down the path. Most of this debris makes it only about 500 feet downslope.
No other obvious signs of instability during the tour.
