Climate change is causing the melting of the Alpine glaciers. This, is disrupting not only the ecological balance but also the representation we have of this environment. The glacier is a central element in the pictorial mountain representation, then photographic. What happen when it is reduced to a congruent part nestled at high altitude? Are the Alps, and their imaginary world, going to be able to withstand the disappearance of their founding paradigm ?Observing the transformation of the alpine environment, I try to re-actualize their representations regarding the upheavals at work.
