Tetons

At the mid and upper elvations soft slabs up to three feet in depth lie on a weak layer of light density snow and slick crusts. Yesterday skiers triggered slabs in TNT chute in Granite Canyon, on a steep north facing aspect of Jensen Canyon, on an east aspect west of Cody Peak known as the North Shore and on a northeast aspect of Wimpys Knob at an elevation of about 7,500 in Grand Teton National Park. The Wimpys Knob event was triggered on approach. Similar events are likely to be skier triggered on steep wind loaded aspects today. Avoid terrain traps and cliff areas.
