Avalanche Summary

You can trigger a large and likely unsurvivable avalanche. You can trigger it from below or from long distances away so be aware of overhead slopes and other parties nearby. Recent reports of loud, rumbling collapses in the snowpack throughout the Elk Mountains are further indications of unstable conditions but you might not see or experience any signs of instability before you trigger a valley-crushing avalanche. A lack of signs of instability does not mean a slope is safe. New snow will only make conditions more dangerous this week. You might be able to trigger an avalanche in the new snow but the real concern is if it steps down to deeper buried weak layers growing in size. You can reduce your chances of triggering an avalanche by sticking to south and southwest slopes at low elevations with a supportable crust below any new snow falling on Wednesday. You can always find safer travel options by sticking to slopes less than around 30 degrees without similarly steep slopes above you.
