From an email "...attached photo of a soft slab avy triggered by a partner today.  It was about 4-10" deep, and about 40' wide, and ran about 1000' vert packing a good wallop.  It was on a northerly aspect around 9800'.  Sort of a wind slab/ density inversion kind of scenario.  Triggered by the second person down the slope."  Photo: B.

    • Two separate storms over the past five days have deposited up to 10" of snow around the Big Sky area. These two storms combined to equal 1.2" of SWE. Although the new snow is well bonded to the hard underlying ice crust, wind slabs remain a concern. Loose, wet avalanches will also be a concern when the sun comes out. Photo GNFAC

    • This photo of a small, sensitive wind slab on an East facing slope was taken yesterday (Sunday, April 4), near Cooke City. Winds are loading upper elevation slopes and instabilities are limited to these soft slabs.  Photo: J. Logan
