Tetons

The avalanche danger is low at all elevations today. Remember that “Low” danger does not mean no danger. Small avalanches are possible in isolated pockets in very steep wind loaded terrain.

It is unlikely that the new snow that fell over the last 24 hours (3-5”) will  be enough to create new avalanche problems today. This new snow is low density (6-7%) and winds have been minimal. Exceptions may be found in very steep terrain (>40 degrees) in the upper elevations. Be on the lookout for isolated pockets of wind slab and shallow dry loose avalanches. These problems become more of an issue in exposed terrain, where moving snow can knock you off your feet and result in a fall. Watch for signs such as shooting cracks and collapsing. Move to lower angled terrain if these signs are present.

Weak snow near the base of the snowpack remains and sits under old hard slabs 2-4 feet thick. This problem has moved into a dormant phase in the Tetons. Large triggers in the form of groups, snowmobiles and falling cornices could activate these layers, but this would be an outlier event. The last isolated event like this occurred 10 days ago in St Patty’s day couloir. Because of these factors, it is important to follow safe travel practices in big steep terrain in the event that your assessment is wrong or your luck has run out. Travel one at a time, utilize islands of safety and communicate within your group throughout the day.
