In thermodynamic, sublimation is the transition of a substance directly from the solid phase to the gas phase without passing through an intermediate liquid phase. During this winter storm, in the heart of the Himalayas range in Nepal, at 5000m, the impression was to assist to the brutal change of the ice into steam. A sublimation. The peaks were Titans fighting, moving, swift a birds of prey. The idea of this project was to translate the intense power of the nature, the dense paradox contains into the term "volatile mountains". The violence, the brutality of these landscape was beyond reason and reached directly the emotions.
