Ontario Sasquatch Investigator Shares Mysterious Growl Capture

# That Deep, Guttural Growl: One Ontario Researcher's Unforgettable Origin Story There's something about hearing a researcher describe the exact moment their entire life's work crystallized around a single sound. That's exactly what happens in this fascinating interview that recently popped up on YouTube, featuring Dennis Ryckman, the dedicated researcher behind the channel Upper Canada Sasquatch. Dennis, who lives in St. Thomas in southwestern Ontario, has been documenting Sasquatch sightings across the region between Windsor and the Greater Toronto area. His channel focuses on investigating reported encounter locations, hiking through the areas, and sharing both the original witness accounts and whatever he might experience while there. But what really caught attention in this interview was how he got started in the first place. Like so many in this field, Dennis traces his interest back to childhood. He remembers being around four or five years old when he first saw the classic film *Mysterious Monsters*, which featured the Loch Ness Monster, Yeti, and Sasquatch all in one go. That movie planted a seed that never went away. He continued following the subject through shows like *Finding Bigfoot* and various Leonard Nimoy-style documentaries, but it wasn't until he was out filming for another YouTube channel of his called Random Adventures that things got real. The story is almost too perfect. Dennis was hiking at a location that had been flagged on one of the online sighting databases, specifically chosen because someone had reported a Bigfoot encounter there. He was at the top of a ridge overlooking a river valley, focused on filming an eagle's nest with an eagle in it, when something went down the ridge to his left. He froze. He didn't turn to look. He didn't even think to turn the camera. He just stayed locked on that eagle. It wasn't until he was driving home a couple of hours later that the realization hit him. He'd had his phone recording the whole time. When he got home and listened back, there it was, a deep, guttural sound that he describes as unmistakable. And here's where it gets really interesting: Dennis did his homework. He ruled out black bears (rare in southwestern Ontario), cougars (who don't make that kind of vocalization), deer, moose, elk, caribou, and wolverines. Nothing in the region produces that sound. His conclusion? He doesn't know what it was, but it's the only explanation that fits. That recording became the catalyst for Upper Canada Sasquatch, and Dennis has been investigating reports across Ontario ever since. His methodology is thorough. He pulls from Ontario Sasquatch, BFRO, Sasquatch Canada, and the Bigfoot Mapping Project to find documented sightings near him, then he visits those locations, hikes through them, and uses a drone to get aerial overviews while sharing the original witness accounts on camera. What makes this interview worth watching isn't just the origin story, though. Dennis touches on something that resonates with researchers everywhere: the frustration of grainy, blurry footage in an age of high-definition smartphones. He points out that even when you have your phone ready, the time it takes to pull it out, open the camera app, and start recording is often enough for whatever you saw to disappear. He mentions catching a great blue heron at one investigation site, and by the time he got his phone out, the bird was gone. If that's how fast a heron vanishes, imagine what happens with something that doesn't want to be seen. The conversation also wanders into the global cryptid landscape, with mentions of the Yowie in Australia, the Yeti in Asia, and the Green Man in Britain, which Dennis notes has ties to ancient Celtic traditions and may represent the same kind of wild, forest-dwelling presence that cultures around the world seem to recognize in their own way. It's a reminder that whatever is out there, it isn't just a North American phenomenon. One thing that makes Dennis's work stand out is the transparency about his process. He doesn't claim to have all the answers. He documents what he finds, shares the original reports, and lets viewers draw their own conclusions. He's also been dealing with degenerative osteoarthritis over the past couple of years, which has limited how often he can get out into the field. He's releasing about one video a month now, and he mentions that a new one is dropping soon that he considers one of his best in the past year. For anyone interested in Sasquatch research in Canada, or just curious about how independent researchers operate in the field, this interview is well worth the watch. Dennis comes across as genuine, methodical, and deeply committed to documenting whatever is happening in those Ontario woods. And that growl he captured? It's the kind of audio that sticks with you.
