“ACROSS emptiness” is the story of an authentic Dolomitic crossing made by a group of splitboarders and ski mountaineers into the alpine void created by the closure of the ski resorts during the winter of 20/21 after the impact of the pandemic. A journey capable of creating the background for a comparison between the emptiness of wild areas and the emptiness left by highly anthropized ones. An opportunity to question the future of alpine valleys, the ski monoculture and the fundamental role of the outdoor community in environmental activism.
