For nearly two decades, Karl Sup has spent thousands of hours investigating Sasquatch activity across Arizona, Illinois, New York, and beyond. His experiences include face-to-face encounters, thermal captures, massive handprints left on vehicles, unexplained vocalizations, apparent infrasound events, and a female Sasquatch observed through night vision at close range.
In this episode, Karl shares the encounter that convinced him these beings are real, including a night in Arizona when a responsive whoop led to a visual observation of a towering female Sasquatch watching from the darkness. He also recounts waking up to find a massive face pressed against his vehicle window, discovering oversized handprints the following morning, and documenting activity throughout the Mogollon Rim region.
Karl discusses his work preserving the historic Bigfoot Encounters archive, his investigations on Long Island and in the Chicago forest preserves, strange incidents involving missing time during a BFRO expedition, and years of research into habitat patterns that continue producing results.
This conversation is packed with field observations, investigative insights, and firsthand experiences from one of the most active researchers in the Bigfoot community.
If you've ever wondered what thousands of hours in Sasquatch territory can teach a person, this is an episode you won't want to miss.
