You can trigger a large avalanche in recently drifted snow. The most dangerous slopes face an easterly direction. These winds will likely drift snow farther down the slope than anticipated, so be cautious of textured snow or snow that resembles a pillow. If you trigger an avalanche in the surface snow, it may step down to deeply buried weak layers. You may get no warning signs before triggering a deeper avalanche, even after multiple tracks cross a slope. You can find safer riding on wind-sheltered slopes or slopes less than 30 degrees.
