You could trigger an avalanche where recent snow and winds built cohesive slabs above older, weaker snow at upper elevations. Avalanches are more likely in areas of drifted snow. Drifted snow often looks smooth or rounded and can sound hollow.
You can find safer riding conditions in lower-elevation terrain sheltered by the wind.
