These large cornices are becoming ripe for breaking off. With facets still lurking near the ground, a cornice could be the perfect trigger for a large avalanche.  Give these beasts a wide berth. Photo: B. VandenBos

The 40cm of new snow is now capping the 5cm thick layer of small grained facets.  The stripe in the pit wall is where the facets are located. CT12/ECTP14 on this layer.  More snow will likely create natural avalanches. This pit was dug above Hebgen Lake, but the snow structure is similar to most of our area. Photo: GNFAC

This small slide ran on a layer of surface hoar and was triggerd on a northeast facing slope outside of Cooke City. Photo E. Wolf
