Report Information

Observation Summary

Snow was dry on all slopes during the early morning hours, as the car temperature gauge read -4 degrees Fahrenheit. Temperatures quickly rose, especially on sunny slopes. Any slope with a touch of south showed signs of warming by noon. Strong west winds drifted snow off high peak, but the snow seemed to sublimate. Traveling on east slopes, we did not observe any cracking or collapsing. Pole probing, you can feel a mixture of layers, but the snowpack is generally weak, and nothing feels drumby or hollow at lower eastly elevation. Probing on an east beach around 11,000' HS was over a meter. The most interesting thing we observed on our tour was two small avalanches on west/northwest slopes that looked remotely triggered in Albany Gulch above Ironton. The slopes that avalanches are fairly low angles, and the avalanches were small but remote. They looked to be a few days old, but the first remote in some time.
