These are five most horrifying avalanches of the last five years in Wyoming, based on the number of deaths.

1. At Jackson Hole Mountain Resort in January 2016, a skier unintentionally triggered an avalanche starting at 9,900 feet. The bottom - called the "toe" - fell to 9,500 feet, where debris and two bodies were found. One of three in the group managed to attach to a tree, and watched friends fade quickly to their deaths.

2. In April of 2011, In Garnet Canyon Meadows, Grand Tetons National Park, two back country explorers were caught, buried, and killed while camped overnight.

3. In May of 2015 at Sickle Couloir, Mount Moran, four back country enthusiasts were caught, with one unscathed, one injured, and two killed. The party was ascending when hit by a natural, wet-loose avalanche. It was very small and relatively harmless to people, but three of the four were swept about 500 vertical feet over rock and ice-covered terrain.

4. In March of 2013 on Ranger Peak at Grand Teton National Park, it was clear and sunny just after a front brought just 2-to-8 inches of new snow, but at elevation 7,400 feet, that was all that was needed for an avalanche. It swept away 2 back country skiers to their snow burial.

5. In December of 2011 at Hayden Creek, south of Cooke City, The Fisher Creek Snotel recorded three feet of snow. The mountains nearby rapidly got a heavy load. Even after an avalanche warning was issued, a vacationer left his wife and dog because he wanted to ski. He quickly lost his life.
