More detailed information about the snowpack: 

The snowpack around Mt Emma is generally heavily wind affected and thinner than when I was in the area 3 weeks ago, except in the most wind loaded spots. Snow surfaces are a mix of wind crusts, wind board, sun crusts, and in some select spots, recycled powder. We dug a pit near the top of the main east bowl in some trees that provided a little protection from the winds. The HS was 60cm and generally consisted of various layers of wind slabs and facets with a thin layer of depth hoar at the ground. We observed some non-propagating results on wind slab-facet interfaces in the mid-pack. We didn't get any results on the depth hoar with a CT or ECT, but a PST on the depth hoar did propagate to the end at 40/100 cm. The depth hoar is hard to trigger but could still propagate given the right load.

Weather today was overcast in the morning with clouds clearing to FEW in the afternoon. Winds picked up in the afternoon with moderate to strong winds along exposed ridges. The winds kept the temperatures cool. We saw a decent wave cloud formation in the afternoon - see picture.
