Avalanche Activity

Intense snow transport above the treeline

Avalanche danger above the treeline is considerable, below that altitude danger is low. Main problem: the freshly generated snowdrift accumulations. Slab avalanches can be triggered by one sole person on steep ridgeline slopes in N/W/S aspects, in gullies and bowls and behind abrupt discontinuities in the terrain. Above the timberline, the danger zones are more numerous. Avalanches can grow to medium size. Wind signs and glide cracks are signs of potential danger.

Snowpack Structure

The loose fresh snow is being transported far-reachingly by easterly winds. Especially above the timberline in wind-protected terrain, behind abrupt discontinuities in the terrain, on ridges and crests, in gullies and bowls, fresh snowdrifts are being deposited atop soft layers of expansively metamorphosed (faceted) crystals. They are extremely prone to triggering.

Tendency

Avalanche danger will decrease only incrementally over the next few days.
