This is an annual event in Argentiere la Besse, showcasing the local ice climbing. I went to the 2008 one which was my second ice climbing trip. It's a great way to meet new people and get detailed local knowledge of ther best places to climb. Organisation is done by Gérard Pailheiret, a local guide, and highlights include, free shuttle buses to climbing venues, gear stalls by sponsors, free equipment testing, film nights etc.

Here's a pic of me on Y-Gauche at Ceillac, a cool little crag towards the Italian border (which has a nice short walk in):
