facets and avalanches.

9th February 2012

This is a piece of film taken on Beinn A Bhuird on Tuesday 9th Feb.
We identified a layer of facets in the snowpack. This layer is widespread in the area.
The same unstable layer is still in the snowpack today despite the thaw.
Today we went into Corrie Fionn on Glas Maol just in time to see a sizeable avalanche release. The visability was poor but it was possibly triggered by a cornice collapsing.
The majority of the snow had failed on this weak layer, the bigger debris blocks were around 1 metre square.
We will be monitoring this layer but meanwhile careful route choice and travel technique should be considered.
Tom surveys some of the debris

Some sizeable blocks.

End of the debris tip.
