Comments
We had a small pocket wind slab release sympathetically [forecaster comment: possibly remotely triggered] while sidestepping up the windward side of a small cornice area. The wind was blowing out of the south for most of the day loading this slope. We were exiting the upper Red Pine lake area and were navigating our way out of lower Red Pine, this happened on the pitch descending onto the lower lake.
Comments
Large surface hoar was observed in the lower elevations.
