Gallatin National Forest Avalanche Center

14" of new snow, deeper in wind loaded areas. The new snow was well bonded to the old snow surface and non-reactive.

Slab above upper crust was 15 mm (H20) in 9 cm snow. Slab in between upper 2 crust was 62 mm (H20) in 27 cm of snow.

Cross loading observed on many aspects; upslope winds observed on S aspects, particularly rock bound couloirs. Large natural avalanche noted that spanned multiple aspects.
