Skiers got surprised when this slab pulled out yesterday.  No one was caught or injured.  New snow and some wind-loading created instability that luckiy did not step down to deeper layers. Photo: Anonymous

This small wind slab near Mt Backmore in the northern Gallain Range was human triggered. Althoug small, it's an obvious sign of instability. This type of slide would be far more hazardous in steep, high consequence terran. Photo D Nicolls

This natural avalanche occurred on the north face of Mt Backmore. Heavy wind loading and weak facets near the ground was the recipe that caused this slide. The crown in the lookers left side of the photo is nearly seven feet deep. Avalanches of this nature will become more likely as more weight and stress is added to the snowpack. Photo B Bakken
