Notes
Riders spotted this large avalanche on the south face of Mount Abundance on President's Day. It was unknown whether it was natural or human-triggered. The group had some sled issues on their way to go check on the situation and retreated to town.
We later determined that it was sledder triggered based on video footage on social media
