Another warm day, with things softening up quickly. Superficial refreezes were quickly eaten up by the warm temps and sun. East aspects were warming up as early as 10 AM.  True north aspects had some near surface faceting but all other aspects had a melt-freeze crust on it.  Lots of variability based on slope aspect and the impact of the sun.  With slopes getting direct sun warming up a lot quicker than slopes that weren't.  We found a lot of cold snow even 20cm down in the snowpack with most of the warm temps and sun only penetrating in the top 20cm.  This again was very dependent on aspect the impacts of direct sun.  Sun has a lot more of an impact on slopes than warm temperatures.  On slopes that were impacted by direct sun, we were finding wet snow down deeper in the snowpack.  This included wet facets 1 to 2' down, but we still haven't found percolation columns.

Video: It's getting warm out there but our snowpack is transistioning from a cold snowpack.  Here are the dangers of wet slab avalanches!
