Trip Planning for Island Park

Bottom Line: Daily forecasts are done for the season, but avalanches will continue. Remain diligent with your snowpack assessments and route-finding, and adapt your decision-making to changing conditions. On Monday and Tuesday, wet snow avalanches are likely. The snow is unstable on a spectrum, from when the upper few inches of the snowpack are wet and slushy to the entire snowpack being unsupportable. Avoid steep slopes and runout zones where these scenarios are present. Beginning Tuesday night, as snow returns to the area, watch for signs of instability within the new and wind-drifted snow, such as shooting cracks, and dig down until you find a supportable crust to test for instability above this level. Avoid steep slopes where you find instability.
