Bishop Bowl/Above Aspendell
Friday, January 18, 2019 - 1:00pm
This avalanche apparently was naturally triggered on Friday 1/18/2019 between 1300 and 1630, the day after the recent storm cycle cleared out. A photo of it was posted on Friday, and since this was a fairly large natural avalanche, R3-D2.5, in a popular area, it merited a closer look. Today (1/20) we toured up to the release zone to see what the bed surface was and what layers failed. In the attached profile, the layer between 47-57 cm above the ground appeared to be the layer that failed - the upper portion of the basal facet layer. The storm layer has gained strength over the past few days.
