The snowpack is thin in most areas. You may find some isolated spots where you could trigger avalanches near and above treeline in places that catch and hold wind-drifted snow. The most dangerous slopes face north, northeast, and east. Unfortunately, any steep slope that harbors continuous snow cover could produce an avalanche. Avoid bulbous pillows of wind-drifted snow on slopes steeper than about 30 degrees, especially below ridgelines or in gully features. Stick to lower-angle terrain as a safer option.
