Avalanche Summary
You can trigger an avalanche where last week's storm snow settled into a cohesive slab above older, weaker snow. The most avalanche activity reported so far has been on northerly and easterly-facing slopes near and above treeline. These slopes are the most dangerous. You may not see obvious signs of instability, like cracking or collapsing, before triggering a dangerous avalanche.
You can find safer riding options on lower elevation southerly slopes, and slopes less than about 35 degrees in steepness.
