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

Extreme flip flops back and forth this winter between wet and warm to cold and clear have made some funky layers in the snow.


Quick pit just below the ridge on showboat (~2300', W aspect) on December 23 verified loose faceted weak layers between thick crusts in the snowpack. Most notable weak layer of very loose facets was halfway down, around 50 cm deep in the 110 cm pit to the ground. Got a CT11 Quality 3 compression failure on this layer. Also below the 4cm of fresh snow at the surface there was a brittle crust with facets sandwiched between the meltfreeze layer from December 14.
