Description:
The danger is moderate on solar (sunny) aspects below 2000 metres. Continuing elevated freezing levels will see the snowpack remain uncohesive. Avoid steep start zones when you are sinking into a wet ,loose, and uncohesive spring snowpack. Limit your exposure under these start zones also as they can release without warning and travel considerable distance. Areas where rocks and gullies can capture the heat are areas to avoid during the warmest part of the day.

Current Snowpack Conditions

Current Snowpack Conditions
Friday the 3rd October and Saturday the 4th saw substantial amounts of snow fall in the park. Most loading was on slopes lee to the southwest but snow accumulated on all but the most wind exposed slopes. On sunday the 5th the snow transitioned from cold dry to heavy wet snow. Recent rain will have saturated the snow pack. Any instability will moderate as the freezing level drops and excess moisture drains out of the snowpack.
