This slide occurred in one of the meadows along the trail to Mt. Blackmore just before the trail climbs out of the Blackmore Creek drainage into the Blackmore basin. This slope gets heavily windloaded at the top. Photo: B. VandeBos

Snowpack and Avalanche Discussion
Northern Gallatin Range
Active wind loading will make many slopes prime to be triggered or to slide on their own. More wind and more snow is expected. Photo: B. VandenBos
These two recent avalanches were spotted just north of Hyalite Peak yesterday on a SE aspect. Seeing naturally triggered avalanches means we can easily trigger slides if we ride in avalanche terrain. Photo: B. VandenBos
The crown from this avalanche that resulted in a fatality as well as one from another recent avalanche can be seen in this photo. Photo: GNFAC
The full burial occurred just out of view of the photo near the toe of the debris. Photo: GNFAC
Faceted snow near the ground was the obvious weak layer in this avalanche. The crown was 1-3 feet deep and propagated 150 yards wide. The slide either failed naturally or was triggered from low on the slope. Photo GNFAC
