We visited the site where two very experienced, avy savvy local skiers remotely triggered this large slide near Slader Ridge in Upper Weber Canyon. The initial slide sympathetically released a large avalanche a couple hundred feet away to the south.

Unlike most hard slab avalanches, rather than shattering like a pane of glass, the raincrust allows the snow to remain intact as one cohesive piece of snow. It finally breaks up as it slams into trees, piling up huge amounts of bone crushing debris.

The raincrust has provided the perfect protecting layer, essentially allowing the surface hoar/facet to combo to remain intact.
