On the central and north coast of British Columbia, the Great Bear Rainforest is the largest intact temperate rainforest in the world, containing more organic matter than any other terrestrial ecosystem on the planet. The area plays host to a wide range of species, from thousand-year-old western cedars to humpback whales to iconic white Spirit bears. According to local residents, another giant is said to live in these woods. For centuries, people have reported encounters with the Sasquatch?a species of hairy, bipedal man-apes said to inhabit the deepest recesses of this pristine wilderness. Driven by his own childhood obsession with the creatures, John Zada decides to seek out the diverse inhabitants of this rugged and far-flung coast, where nearly everyone has a story to tell, from a scientist who has dedicated his life to researching the Sasquatch to members of the areaâs First Nations and a former grizzly-bear hunter-turned-nature tour guide. With each tale, Zada discovers that his search for the Sasquatch is a quest for something infinitely more complex, cutting across questions of human perception, scientific inquiry, indigenous traditions, the environment, and the power and desire of the human imagination to believe in?or reject?something largely unseen.
