Evidence from the late Feb cycle is prominent out there, especially on solar aspects. We noticed the southeast aspects of Arrowhead likely ran . It was hard to tell if it ran in the last weeks warm up or during the late feb cycle.Signs of Unstable Snow
Observations
We found a mixed bag of weather and snow types on this tour. Weather wise, today we experienced some warm sun breaks followed by strong West winds and snow squalls that accumulated upwards to an inch of new snow.
Snowpack wise, at lower elevations we found firm and supportable travel. At the mid and upper elevations we found a mix of colder snow on a sun crust or just a crust layer that was stripped from the westerly winds. Near ridge top we started experiencing shallow, but touchy pockets of wind drifted snow. We suspected lee aspects could hold larger pockets of sensitive wind slabs below ridge top. Winds were cranking in the strong category and transporting the 1-2 in of new snow. It appeared southern aspects off the Arrowhead ran during the most recent cycle, which made for slide for life conditions at upper elevations. Other noteworthy observations we made, was that we noticed westerly aspects held evidence of recent wet loose activity from our recent warm and sunny days.
