On the Shoulders of Giants - "Only what has passed or changed or disappeared reveals its true face.“ (Cesare Pavese) During my trip I followed the steps of great photographers, Ansel Adams and Thomas D. Mangelsen, rediscovering landscapes and places they photographed. Climate and environmental changes can alter a territory, so, thanks to the inspiration of past works, I tried to document its transformation and reveal its current face. Yellowstone National Park surprises you with its pristine nature; founded in 1872, it is the largest protected area in the US, covered with grassy plains, forests and sulfur springs. Spanning over 300 km of roads and trail you can meet over 60 different species of mammals, numerous species of birds, fish and invertebrates, a true oasis of biodiversity and wildlife.
