Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Overcast to broken skies. Calm winds. Temperatures in the upper 20'sF at 3,000' as well as 1,000'. Inversion with valley fog. No precip.

Snow surface

2-8" of loose powder snow. Winds from Friday have affected snow surface in exposed locations.


2,000': Poached a pit from Nate and Nick (thanks!) in Main Bowl/1st Bowl. A 1-2" melt freeze (crumbly) crust exists 4-6" below the surface. Under this the buried surface hoar sits around 20" deep and was stubborn, reported to fail on shoulder taps - ECTP 20's. There was thin spot in the pit that had an ECTP 12 in facets between crusts - something to keep track of.

3,000': 18" slab sitting on buried surface hoar (1cm). ECTP 19 and 22 sudden collapse. Again, felt like it wanted to be stubborn but it did have a little pop to it. See video and photos.
