Before hydroelectricity development and tourism activities, Maurienne territories have been exploited for a long time. Roads of the Mont-Cenis have crossed the Alps since Hannibal times. Over the years, railroad pioneers experienced different trails in the region. Today a new passage is being dug, and it testifies both the completion of an old transport ambition, as much as, the emergence of global needs in moving goods. The drilling of the Lyon-Turin tunnel crystallizes the relationship with time disparities. A coveted time, whose incompressibility tries to be abolished by an obstinate search for speed. This is a Trans-European essential link whose legitimacy is also reprobated. As an ephemeral compromise between anthropic interests and natural constraints, landscapes are also the support of economic convulsions and contain evidence of past and future threats. To what extent can we consider that technology makes the world suitable to live in? Is there any disconnection between economic time and natural human timeframe? What is the threshold making a resilient environment permanently modified and hostile for humans? Without offering direct answers, these issues are covered throughout this series. The image approaches vary from poetic evocation to documentary investigation.
