Small avalanche on Ben Nevis, 8 May 2016

I saw this small avalanche when I was near the Carn Dearg summit (NW of Ben Nevis summit) at 3:20pm on 8 May 2016.. This started in the gullies near the top of the summit plateau, well west of Tower Ridge. The first 6 seconds is a still photo showing the start of the avalanche (near the centre of my photo), the next 12 seconds is video footage. I think the avalanche was caused by cornice collapse in the recent warm weather. I saw 2 other avalanches that day (in Point Five gully area) which also was likely due to cornice collapse.
