Gallatin National Forest Avalanche Center

Avalanche: 150' wide x 200' vertical x 2.5' deep Remote trigger from flat terrain 10' uphill of crown

Introduction to Avalanches class snowpit location adjacent to but outside ski area boundary in a backcountry/undisturbed snowpack. Consistent scores between ECTP12-14 at 60 cm down from surface. We performed approximately 10 ECTs in this location. Depth hoar another PWL of concern; suspect surface slabs could step down to depth hoar.
