Glory Bowl avalanche

Riley Doyle, 26, was delivering water to Teton Valley, Idaho, for JH2O Water Condition and Filtration when an avalanche swept out of Glory Bowl just after noon Thursday. The avalanche danger was rated as considerable at mid- and upper elevations that day, and the Bridger-Teton Avalanche Center has increased the danger rating to high at those elevations for Tuesday.

Stay safe out there today, folks. 

The Bridger-Teton Avalanche Center has moved the avalanche danger to high at midelevations. The danger rating is high for all slopes above 7,500 feet. 

Jackson Hole Mountain Resort reported 13 inches of snow at the Raymer plot, while Grand Targhee Resort saw 7 inches in Chief Joseph Bowl. With 8 to 10 inches predicted to fall in the next 24 hours, the load continues to increase on buried weak layers that range from deep, persistent instabilities to density shifts in the new snow.

Winds are expected to stay strong, at 25 to 35 mph on ridge tops. That will elevate the wind slab potential, which the Avalanche Center daily bulletin says is present on all aspects at all elevations. Any wind slabs that release could be up to 3 feet deep. If they fail on a slope that also has the persistent weak layers (west, north and east aspects above 9,500 feet, and north aspects above 8,000 feet), the slide could step down to the deeper layers.

A deep slab slide released naturally yesterday on Drew's Slide in the backcountry to the south of Jackson Hole Mountain Resort. The 48-inch crown was on a northeast aspect and had a destructive potential of 2.5, meaning it could easily bury, injure or kill people, according to the United States Avalanche Rating Codes.

See Wednesday's Jackson Hole News&Guide for more discussion of the recent storms and how they have affected the snowpack. See the Avalanche Center's website for the most up-to-date information on recent slides and weather.
