Notes

Today in Hyalite there was roughly 5" new snow. It quickly lost cohesion when the sun came out and many size 1 dry and wet loose came off of steep rocky areas. I did not observe anything larger. Yesterday I observed a cornice fall on an E aspect of Mt. Bole around 9500 ft that probably occurred on 3/6. It ran several hundred meters downhill, entrained some surface snow, and appeared to trigger a size 2 slab when it encountered steeper terrain. That being said I was at G1 so I didn't really get a good look at it.
