Baby Bigfoot Warns Engineer of Impending Flash Flood

There's something about a first-person account that hits differently when the storyteller has zero reason to embellish. Carter Mills isn't a researcher, isn't a podcaster, isn't selling merch. He's a 63-year-old retired hydrological engineer from Boise, Idaho, who went on a solo camping trip in June 2017 and came home with a story that has clearly lived rent-free in his head ever since. The video in question, posted over on the Bigfoot Records YouTube channel, walks through what Mills describes as roughly four hours of a juvenile Sasquatch attempting to communicate with him about an impending flash flood in the Payette River drainage of the Boise National Forest. And here's what makes it genuinely compelling: Mills isn't some wide-eyed true believer. He's a guy with 37 years of professional hydrology experience who spent most of those four hours dismissing what was right in front of him. The encounter begins around 9:15 a.m. when Mills notices a small reddish-brown figure, approximately three feet tall, standing at the tree line about 30 meters upstream. He registers it, files it away as "probably a bear cub," and goes back to his coffee. Classic human move, honestly. The figure moves toward the creek, looks at the water, looks at Mills, looks at the water again. It makes a brief, high sound directed specifically at him. Mills hears it and categorizes it as "wildlife sounds, non-threatening." This is where the story gets interesting, because Mills is reconstructing his own failures in real time. He's not telling you a tale of triumph. He's telling you about every moment he got it wrong. By 10:40 a.m., the juvenile is blocking the downstream trail at 20 meters. It makes the same sound, sustained this time, with rhythm and emphasis. Then it does something Mills has replayed in his mind countless times: it points upstream. Not a casual gesture, a full-body orientation, face, chest, one arm all aligned upstream, held for several seconds before locking eyes with Mills again. The "did you receive the information?" look. Mills interpreted it as territorial display. He went downstream. The juvenile followed at 20 meters, persistent, unwilling to abandon whatever mission it was on. Over the next two hours, the creature escalated. It blocked the trail twice more, always pointing upstream. At the one-hour mark, about five miles from the trailhead, it made actual physical contact, a small hand on Mills' right calf, insistent, tugging at his pant leg before pointing again. Mills' response, spoken out loud to a baby Sasquatch in the Boise National Forest: "Hey, cut it out." That line alone is worth the watch. The breakthrough comes around 12:27 p.m. The bird song has vanished. The air temperature has dropped inconsistently with cloud cover. The creek's sound has shifted to a lower frequency, louder, with the acoustic signature Mills recognizes professionally as increased upstream volume. The juvenile sits down directly in the trail, not blocking, just committing. Its eyes, Mills describes, are no longer dismissible. They're wide, terrified, holding a silent plea. Then the roar arrives. A deep, sustained, building sound from approximately a mile and a half upstream. The creek jumps eight inches in 15 seconds, color shifting from clear green to opaque reddish-brown. The lower trail Mills had been walking for three miles goes underwater within 90 seconds. He was 30 seconds ahead of the surge because a juvenile Sasquatch sat down in his path and refused to move. The cause, Mills learned later, was an overnight dam failure of a snowpack-fed lake roughly six miles upstream. Not catastrophic regionally, but absolutely catastrophic for a solo hiker in a drainage bottom. What makes this account stand out in the broader Sasquatch literature is the framing. Mills isn't claiming the creature was psychic or supernatural. He's claiming it had superior knowledge of the local drainage, knowledge that exceeded his own professional expertise. A juvenile Sasquatch, in his telling, understood the hydrology of that specific watershed better than a human engineer with four decades of experience. And it tried, for four hours, to communicate that knowledge using every tool available to a non-verbal, non-human intelligence: vocalization, body orientation, blocking behavior, physical contact. The interspecies communication angle is what elevates this beyond a standard sighting report. Mills spends significant time in the video unpacking the idea that the barrier between humans and Sasquatch isn't linguistic, it's willingness. He argues, with the benefit of hindsight, that he received every piece of information he needed and simply refused to process it because it didn't fit his existing framework. It's a rare kind of witness testimony, one where the witness is essentially indicting himself. And the fact that he's a hydrological engineer, someone whose entire career was built on reading water and terrain, makes the failure to read the signs that much more pointed. The video is worth the full watch. Mills' delivery is measured, almost professorial, and he doesn't sensationalize a single moment. He just lays out the timeline and lets you draw your own conclusions about what was happening in those woods on June 14, 2017.
