Our exhibit about Yellowstone is accompanied by quotes from Great Indian Chiefs; it's a tribute to the American Bison, the Wapiti, and the North American Native culture, which was so linked to nature and animals. « What is life? It is the flash of a firefly in the night. It is the breath of a buffalo in winter. It is the little shadow that runs in the grass and gets lost at sunset. » Crowfoot (Blackfeet Indian Chief).
