In sintesi

Wind slabs may be forming in unusual spots due to northerly winds. Ice climbers, watch out for spin drifts from above.

Problemi valanghivi

    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità

    Dimensione
    1–2

    These slabs are sitting on old hard surfaces (old wind slabs, temperature and sun crusts).

  • Loose Dry
