Quick report
Entered Tuckerman Ravine at 1245 to look at the new snow and its interaction with the previous layers in the snowpack. Found the snow to be Fist hard, and at the time, evenly distributed. Unlikely to remain this way as winds have been increasing from about 1500 on and will continue to increase in speed through the night. Went up to the rock buttress between Sluice and Right Gully to dig as have been frequenting this area. Noted that Sluice was far more convex today and was holding more snow (compared to yesterday where it had appeared flat). Chose not to pop into this snow to dig and also chose not traverse it to ski Chicken Rock Gully as we had done yesterday. All results were 25 cm down on a graupel layer and density change with clean shears. The Fist hardness new snow sat on a 1F slab. Walking on this you could feel the slab beneath compress. Snow pit results were CT12 and ECTN18. The ECT was stubborn and only cracked underneath the shovel. Multiple layers of graupel are visible in the top layers of the snowpack and have consistently had weak interfaces over the past few weeks. The older slab was very cohesive and while it has not been propagating is something to keep an eye on as there are multiple weak layers in the snowpack currently. Multiple hand shears showed to be very clean with graupel underneath.
Avalanche
Observed a natural crown line to the side of the lip that we estimated to be about 3 in. Below that are just wind lips that were observed yesterday.
