Notes

These avalanches were seen on 01/30/2024. They likely happened on the close to 01/29/2024 towards the end of a recent storm.  

From ob on 01/30/2024: "Over 15 slides spotted on our ride today. Both large and small. Mostly south facing slopes with a large one on a north facing slope. Several hills with visible cracking and ready to let loose." 

Update from email on 01/31/2024: "The slides were very fresh i would say happened the day of or day before I saw them. I rode the same area Sunday (no slides noticed but it was raining) as Tuesday (when we noticed an abundance of them)."
