Gallatin National Forest Avalanche Center

Recent avalanche further north on same ridgeline. R2-D2-O, 1-2+ days old. 150' wide, 250' vertical. Looked to be snowbike triggered, and likely broke on the surface hoar layer, 1.5-2' deep. Some tracks crossed slope 150' below this pit which headed towards the avalanche, and appeared to be the trigger.
