Comments

Traveled from 7400'-10,500', mostly north half of the compass.

A lot of water weight has been added to the snowpack in the last several days and the buried week layers have been failing naturally. Tomorrow's warm temps will most likely activate these layers in places and definitely make them more sensitive to failure. The avalanche danger is widespread through elevation as the lower elevation terrain has seen rain and snow and upper elevation terrain, snow and wind. Test results reflect a moderate to hard effort to produce failure but weaknesses in the upper snowpack were easier to activate. Step down avalanches are a big concern. I did get one CTX score that failed on 1-2mm facets 18" off the ground.

Consequences are high if you do trigger a slide so terrain choices are critical in travel decisions.
