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

There was about an inch of new snow in the parking lot this morning, and it seems that most of the pass was spared from rain. It was very windy with gusts up to 40mph, our skin track was actively filling in between laps today. At times we had precipitation rate of two centimeters an hour, winds made estimating new snow difficult

Snow surface

Snow surface is still a mixed bagged but seemed to be improving. Sastrugi and new 4finger to 1 finger wind slabs could be found throughout our tour.


Our snow pits had poor structure, low to moderate strength and high propagation potential. One of the most dramatic results from the day was an extended column test that propagated on one tap from the wrist on a recently formed wind slab. After seeing these results in our pits and observing other red flags we decided to not continue towards hatch peak.
