Written Report:
Started off 2021 with a beautiful bluebird day skiing around the Paulina Lake area. The most recent storm has settled to about 8in and has been kept cold on North and East aspects making for fun riding conditions in sheltered areas. During the day my partner and I made two observations including stability tests.

The first pit we dug was on an exposed NW aspect at around 6700' (photo below). In this pit profile, we found a 155 cm deep snowpack with an 8" wind slab on top of a thick rain crust. This slab reacted at ECT4 but did not propagate. The snowpack below the rain crust seemed very solid to the ground with no other obvious weak layers or facets and clear signs that the rain had percolated deep into the snowpack. We did not find a wind slab this thick anywhere else throughout the day and there was no slab in sheltered areas.

The second pit was on a NE aspect at 7000'. The snowpack in this location was only 115 cm deep and had the same rain crust 8 inches below the surface with a less consolidated slab on the top.

We did not observe any major red flags other than old avalanche debris on a 35 degree slope below Paulina peak.
