Snowmobilers and cross-country skiers are advised to stay out of the back country and stick to groomed trails this weekend.
Fremont County Search and Rescue Commander Justin Liebert said storm totals for the area are close to 20 inches, totaling 2.1 inches of Snow Water Equivalent. The rapid and heavy load has pushed snowpack past its breaking point, making natural human-triggered avalanches likely.
Large and very dangerous avalanche conditions exist throughout the region. Danger is rates as “high” to “extreme” in the Centennial Mountain Range including Mt. Jefferson, Reas Peak, and Sawtelle Peak. Avalanche danger near Two Top Mountain, northeast of Island Park, is also rated as “high”.
Conditions Saturday were expected to worsen.
Liebert encouraged all recreationists who don’t possess the training or equipment to take advantage of more than 500 miles of groomed trails in Fremont County.
Fremont County conditions are not specifically covered by forest avalanche centers, but always mirror those of those in Montana and western Wyoming.
