Lo esencial

Deep full depth slabs can still be triggered with explosives and also could be human triggered from a thin spot or rocky area. Conservative route selection will give good ski quality without excessive exposure. JBW

    There are some small fresh wind slabs and ripe cornices that could be triggered on lee features. In some cases the slabs may be enough to trigger the deep basal instability.

    Avalanche control on the Sunshine road today produced some full depth slabs as thick as 1.5 metres that were running fast and quite far. These avalanches failed on the ground and October crust and show that human triggering is still a possibity.
