The most dangerous areas are wind-loaded slopes above the treeline where you find around 10 inches of wind-drifted snow. Avoid areas below ridgelines and in cross-loaded gullies with a rounded snow surface or where the snow feels hard underfoot. Avalanches in the new snow could break deeper into weak snow layers near the ground on slopes that face north, northeast, and east. Pay attention to the direction a slope faces and choose an alternative route on lower-angle slopes if you see cracking in the snow or hear rumbling collapses.
With ample sunshine and rapidly warming temperatures, watch for small loose avalanches from steep, rocky terrain by early afternoon and avoid traveling above terrain traps like cliffs, gullies, or creek beds.
