CREUZETTES CHAT CROISSANT CHATGUERETS CHATEAU CHATEAU
This appears to be a list of French place names or trail/lift names—likely ski runs or sectors at a French alpine resort (many "Château"-prefixed locations plus names like Creuzettes and Chatguerets suggest piste names, possibly at Les Sybelles or a similar area). Without further context, the text itself doesn't describe an event, just a roster of location names.
