Bigfoot Researchers Analyze Mysterious Tree Markings in Washington

So I stumbled across this fascinating Q&A session over on the Creek Devil YouTube channel, hosted by William Jevning, a two-time witness and field researcher with over four decades of experience in the field. The discussion dives deep into one of the most intriguing behaviors attributed to Sasquatch: tree pushing and territorial marking.
The conversation kicks off with a viewer question about reports of Bigfoot cutting down or moving trees to indicate territorial boundaries or direction of travel. What unfolds is a genuinely compelling exchange between Jevning and his panel, including someone named Forest and Chuck, who all bring unique perspectives to the table.
One of the most jaw-dropping moments comes when Jevning recounts a discovery he made back in 1991 while exploring the Washougal River watershed in Skamania County, Washington. After multiple attempts to access the difficult terrain, he and his friend Jack hiked up to a ridge saddle that sat between two drainage systems. This area was significant because there had been numerous sightings on both sides, and they theorized it might be a travel corridor.
What they found was extraordinary. A Douglas fir tree, about 15 to 20 feet tall and three inches thick, had been broken at a precise 90-degree angle, exactly 8 feet and 1 inch off the ground. No disease, no markings, no weather damage. Just a clean break. And it wasn't alone. As they investigated, they discovered a total of 13 trees broken in the same manner, all in a line heading northeast.
Here's where it gets really interesting. Jevning showed the photos to a Native American friend, who chuckled and said, "Oh, you finally found that." According to this contact, what Jevning had discovered was a territorial marker, a sign left by the dominant male of a group indicating the direction they were traveling to their next feeding area. The Klamath folks apparently confirmed this interpretation as well.
Jevning makes a solid point about distinguishing natural occurrences from intentional ones. During a 30-mile drive through Oregon forests, he challenged his companions to spot similar broken trees. Not a single one was found. That's the kind of absence-of-evidence argument that carries weight, because if these breaks were common or weather-related, you'd expect to see them scattered throughout the forest.
The discussion also touches on twisted branches, with one panelist describing how 2 to 3-inch thick limbs on his cedar trees were pulled down and twisted in a systematic pattern across multiple trees in a row. Wind doesn't do that. Snow load doesn't do that. Something with significant strength and intentionality was at work.
There's also a historical reference worth noting. Jevning mentions an article from a 1963 Sports Afield magazine, originally describing events from the 1940s in Alaska. Trappers in the area had encounters with Diné (Navajo) natives who were familiar with these beings. The natives reportedly had a mutual respect with the trappers, respecting each other's traps and territory, even though they didn't directly communicate. The article apparently describes similar territorial marking behaviors.
The panel also briefly touches on tree structures, including X marks and what might be nursery sites, though they wisely decide to save that deep dive for another session. Forest mentions being intrigued by the X patterns, while acknowledging that Chuck would be better equipped to theorize about their purpose.
For anyone interested in Sasquatch behavior beyond just sightings, this is a worthwhile watch. The conversation covers territory marking, nest building comparisons to other primates like chimpanzees and gorillas, and the subtle signs that experienced researchers look for when distinguishing Sasquatch activity from natural forest events. Jevning's decades of field experience shine through, and his methodical approach to documenting evidence is exactly what serious research demands.
