Avalanche conditions are dangerous. You can easily trigger a large and deadly avalanche at all elevations and on most aspects. Avalanches at mid and upper elevations are breaking wide and deep. Although avalanches may be smaller at lower elevations, they are easier to trigger and can be deadly too. Cautious route-finding and conservative decision-making are essential for safe backcountry travel. Avoid traveling across or underneath slopes steeper than about 30 degrees that could produce an avalanche large enough to bury you.
