This small slab was triggered by a skier near Mt Blackmore in the northern Gallatin Range on Sunday 2/22/15. Although small, this type of slide can be dangerous, especially if triggered in steep, high consequence terrain. Photo K. Lalli
This natural avalanche was observed near Mt Bole up Hyalite Canyon. This slide likley released during or immediately after the storm that dropped nearly 20" of new snow in the northern Gallatin Range. Photo GNFAC

"Triggered two small avalanches in wolverine bowl today. One started from sluff we kicked off while descending from the ramp into the bowl. The second was triggered by my friend on a 40 degree SE convex slope. The crown was no deeper then 1 ft, but it broke over 150ft wide. Not enough debris to be scary, but with another foot of snowfall I would worry. Both slides broke on a soft crust at the new/old interface." Photo: P. Dixon
