Avalanche: Turnagain
Location: Sunburst
The APU Snow Science II class traveled to the Glide Avalanche on Sunburst to take observations of the slide and continued searching for a reactive layer. The students toured up to around 1900ft where a snow profile was completed. Students also took measurements of the avalanche crown, runout and debris starting around 2100ft. The ski conditions were very good and the snow was not too wind affected.

Observer Comments
Several glide cracks in Turnagain noted on the drive.
Weather
Temperatures in the upper teens and low twenties with a light NE wind. S1 precipitation for the majority of the day with brief moments of gusting wind. Snow was seen to be blowing up on the ridgeline in strong gusts.
Snow surface
Great skiing and riding conditions. There was .5mm of stellar snow that landed while completing the pit observations. Just around treeline is where the group started to notice some wind effect.
