In mid and upper-elevation terrain, look for smooth, rounded pillows of wind-drifted snow on the lee sides of ridges, sub-ridges, and other terrain features. These drifts often appear chalky, hollow, or textured compared to the surrounding snow. These lingering wind slabs can pack a punch and may break deeper and wider than expected, as seen with the Room of Doom avalanche above.
With an increase in northwest wind, be especially cautious of fresh drifts just off ridgelines and below cornices. Watch for cracking or collapsing in the snow around your skis, board, or sled - clear signs that the wind-drifted snow is unstable.
