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

Sky - Few
Wind - Light E/NE
Air Temp - -5 deg C

Snow surface

Below tree line - a breakable melt/freeze crust ~5cm thick
At Tree Line - the crust thinned and eventually disappeared
Above Tree Line - Light density dry snow, wind packed in spatially variable pockets


In alpine elevations the snowpack mostly consisted of ~20cm of light density dry snow on top of a more dense, more moist layer that served as a base. Wind packed pockets had a more dense wind layer on top of the light density snow.

See pit profile for more information.
