Awarded a Guggenheim Fellowship to investigate the legends of Sasquatch, Yale–trained ecologist Dr. Robert Pyle treks into the unprotected wilderness of the Dark Divide near Mount St. Helens, where he discovers both a giant fossil footprint and recent tracks. On the trail of what he thought was legend, he searches out Indians who tell him of an outcast tribe, the Seeahtiks, who had not fully evolved into humans. A handful of open–minded biologists and anthropologists counter the tabloids Pyle studies, while rogue Forest Service employees and loggers swear of a vast conspiracy to deep–six true stories of unknown, upright hominoid apes among us. He attends Sasquatch Daze, where he meets scientists, hunters, and others who have devoted their lives to the search, only to realize that “these guys don't want to find Bigfoot―they want to be Bigfoot!” was the inspiration for the 2020 film , starring David Cross and Debra Messing. Since the book’s original publication, Pyle’s fresh experiences and findings have been added to his original work through an updated chapter. With an evaluation of recent DNA evidence from Bigfoot hair and scat, the study of speech phonemes in the “Sierra Sounds” purported Bigfoot recordings, an examination of the impact of the wildly popular Animal Planet series Bigfoot Hunters, the reemergence of the famous Bob Gimlin into the Bigfoot community, and more, keeps every Bigfoot enthusiast’s mind wide open to one of the biggest questions in the land and brings Pyle’s work on the “legend” of Bigfoot into the new century.
