In 1924, a group of gold prospectors led by Fred Beck claimed they were attacked by massive, hairy, ape-like creatures in a remote Washington canyon—an event that became one of the most infamous Bigfoot encounters in history. Siege of Ape Canyon brings this harrowing tale to life with expert interviews, gripping historical analysis, and, for the first time ever, on-the-ground footage of the actual cabin site. Featuring exclusive insights from researcher Marc Myrsell, who has spent years unraveling the truth behind the event, this documentary peels back layers of myth, legend, and evidence to uncover what really happened in the shadowy depths of Ape Canyon.
