Riding around Buck Ridge we found a hard slab of wind-drifted snow sitting on top of weaker facets. Around the corner from the snowpit a snowmobiler triggered a slide on this layer.#gnfacobs

Winds gusted into the 50s mph overnight and formed unstable, hard drifts of snow. In the Bridger Range we found these hard slabs, which collapsed and cracked on buried weak surface hoar and facets. #gnfacobs
