Hal Recalls 1977 Bigfoot Vocalization at Standing Rock

There's something about old-school encounters that just hits different, and a recent interview over on the Bigfoot Society YouTube channel delivers exactly that kind of story. Jeremiah Byron sits down with a man named Hal, who has been fascinated with Sasquatch since he was just a kid reading a condensed Reader's Digest article back in 1969. That article featured clips from the Patterson-Gimlin film, and Hal was hooked from day one. But what makes his story really stand out is what happened years later, in 1977, when he made his way up to the Standing Rock Reservation near Little Eagle, South Dakota, right in the middle of one of the most talked-about Sasquatch flaps in history. For those who might not know, the 1977 Little Eagle flap was a big deal. Reports were flooding newspapers and TV stations about sightings on and around the Standing Rock Sioux Reservation. Hal, who had broken both arms in a rodeo and was off work, decided to drive six hours north from his home in South Dakota to see what he could find for himself. That's the kind of dedication that speaks volumes. Once there, he connected with Gary Alexander, who ran the local trading post and had recorded audio of the creature howling, along with plaster castings of footprints. Hal even joined a small group that included magazine writers and a guy with a serious piece of equipment — a Vietnam-era sniper scope belonging to the Bureau of Indian Affairs that lit up the night like daylight. They headed up onto a ridge, while folks down below had a campfire going. Now, here's a detail that might raise some eyebrows today: the group down below was reportedly using a female menstrual napkin as an attractant, based on the old belief that Sasquatch were drawn to campfires, women, and certain scents. It was a different time, and tactics like that were part of the folklore back then. After the magazine writers called it a night, Hal went back to his pickup truck, rolled up the window, and tried to get some sleep. That's when it happened. He describes hearing something that was somewhere between a howl and a whale — three shorter sounds followed by one long, high-pitched blast. He estimates it was at least 600 feet away, maybe more, but it was so loud it was hard to tell. Based on the pitch, he believes it was a female calling out to a mate. It didn't sound threatening, just powerful. And here's the part that always gets people — after the call, every dog in the nearby village started going crazy, and coyotes up on the ridge joined in. The whole area lit up with canine responses. Hal mentions that he's heard accounts where everything went silent after a vocalization, but his experience was the opposite. The K9s went wild. Hal also stumbled across some of the plaster castings that had been made in the area, and he points out something important: they weren't in places where someone would naturally fake tracks, and they didn't have that overly smooth look that hoax prints usually have. To him, they looked legit. But there's another piece of this interview that might be even more intriguing. Hal recalls seeing a documentary in theaters around that same era — late 1960s or early 1970s — that included what he describes as government footage of a Sasquatch walking through the Everglades, filmed from a plane. He says it was brief but compelling, and he remembers it being some of the best footage he'd ever seen. The thing is, he's spent years trying to track down that footage and the movie it came from, and it's just... gone. He even found one person online who confirmed the footage was filmed near where he lived and that no one in their right mind would have been walking around in a hot suit in the Everglades with all the cottonmouths and gators. That piece of lost footage is a mystery in itself, and if anyone out there knows what documentary Hal is talking about, it would be worth digging into. Hal also mentions that he runs the Bigfoot Without Spam Facebook group, which is a great resource for anyone looking to connect with others who take this seriously without all the clutter. This is one of those interviews that really captures what the early days of Sasquatch research felt like — the newspaper clippings, the trading post recordings, the plaster casts, the late-night vigils, and the kind of encounters that stick with a person for a lifetime. Hal's story from the 1977 Little Eagle flap is a firsthand account from a pivotal moment in Sasquatch history, and it's worth the listen.
