In the New Year I shall be doing a presentation roughly based on how the Earth's topography is constantly changing.
Among other things I wanted to mention rockfalls in the Grand Couloir Gouter and the extent to which the Mer de Glace has diminished over the years.
Does anyone know where I could get some images or videos of these two features. Ideally the Grand Couloir needs to illustrate the rockfall - the more dramatic/spectacular the better.
There shouldn't be any copyright concerns - it's strictly non-commercial.
Many thanks if anyone can help.
