Weather Comments
Moderate to strong southwest winds kept the snow surface above treeline cool. Air temperatures at nearby weather stations just under 11,000' were in the high 30's and low 40s °F. Some cloud cover moved in through the tour.

Snow Characteristics Comments
Snow surface was a solid melt-freeze crust earlier in the am and we followed the sun around the compass to find the softest skiing and to avoid leaving marks behind. Today, we stuck to slightly lower angle slopes that didn't have roller balls or wet loose avalanches on the surface. The snowpack below 9,000' was less supportable if you got to close to the trees. Once you got close to trees or brush, we were breaking through the damp melt freeze crust to the damp snow below. We stayed away from trees and steep damp slopes later in the morning.

Comments
Photo of snow runnels, in the basin and melt-freeze crust on the surface above 10,000' in elevation. Snow runnels can often be seen as signs of stability and show where melt water has run through the snowpack.
Today, we timed our tour to avoid wet avalanches and poor travel due to wet snow. I would imagine the avalanche danger would rise to considerable later this afternoon. Many weather stations in the forecast region have not had a solid air temperature refreeze in a couple of days at higher elevations. See chart below showing temperature at nearby 11,000' weather station. The snow surface has still been freezing at night due to clear skies, and although the window for soft supportable skiing has become smaller, we are still finding soft turns. If we see cloud cover and no refreeze tonight, then tomorrow could have a damper snow surface and we may be more likely to see wet slab avalanches if temps, cloud cover, and slower wind speeds all line up.
