CURIOSITY, now in its second season on Discovery Channel, brings the ‘I wonder?' moment to television with a unique array of provocative subjects.

Created in 1872, Yellowstone is the first national park in America. It is an American cultural icon attracting millions of visitors each year. But there is more to this park than meets the eye. Why is the wolf and elk population dwindling? What triggers deadly avalanches? What makes peregrine falcons one of world's most lethal hunters? CURIOSITY will take viewers inside the hidden wonders of Yellowstone using new imaging technology and the latest scientific research to shed insight on its incredible wilderness.
