Coire Fionn Debris
13th March 2018
Strange weather today: The North half of the area had generally clear weather with a lot of sunshine and the Southern half had thick cloud (occasionally lifting a little) and snow showers. There were also some bands of warmer air pushing through with positive air temperatures recorded at 1000 metres when Cairnwell station was recording negative readings…
I wanted to have a look at the Garbh-choire avalanche today but after skiing half way there in the thick cloud I realised that I wasn’t going to be able to see anything so I came back to Glas Maol and went into have a look at the Coire Fionn debris site….Huge! This was a very large avalanche with tons of debris – small car size blocks and a two metre plus crown wall.
This avalanche, the Garbh-choire of Cairn of Claise avalanche and the two smaller ones that released on the West wall and black run on Glas Maol all went on Saturday night after a day of strong winds that increased significantly late afternoon and with persistent precipitation. All this fresh windslab loaded onto aspects that were already marginal with poorly bonded windslab present.
Apologies for the flat light photos: I waited as long as I could but the cloud never properly lifted for me.
