Canada’s Great Bear Rainforest is home to trees as tall as skyscrapers and moss as thick as carpet. According to the people who live there, another giant may dwell in these woods. For centuries, locals have reported encounters with the Sasquatch—a species of hairy man-ape that could inhabit this pristine wilderness.

Driven by his childhood obsession with the Sasquatch, yet trying to remain objective, journalist John Zada seeks out the people and stories surrounding this enigmatic creature. He speaks with local Indigenous peoples and a Sasquatch-studying scientist. He hikes with a former bear hunter.

Soon, he finds himself on quest for something infinitely more complex, cutting across questions of human perception, scientific inquiry, Indigenous traditions, the environment, and the power of the human imagination to believe in—or to outright dismiss—one of nature’s last great mysteries.
