Avalanche Gulch / Old Ski Bowl
A wide-ranging tour of the Old Ski Bowl, below, near and above treeline to 10,000 feet on Green Butte Ridge. No recent avalanches or red flags of instability were observed. Snow surfaces are varied.
Above treeline - scabby wind affect, wild sastrugi features, some several feet tall over moraine convexities and ridges where wind speeds are highest. Other less windy places have moderate to minor surface texturing. Low-lying gullies out of the direct sun still remained soft and smooth.
Near treeline - transitional snow, sun crusts, soft powder, minor wind affect in exposed areas. Roller balls on sunny slopes.
Below treeline - soft snow in the shade, crusts in the sun. Tree bombs and dripping trees have pounded the snowpack below. Open forest in shady terrain is the best riding.
