Veteran Aerial Surveyor Captures Thermal Bigfoot Sighting in Montana

Okay, folks, buckle up because this one is a doozy. A 63-year-old aerial surveyor with over three decades of experience and 4,000+ flight hours under his belt has come forward with thermal drone footage from the Pioneer Mountains of southwestern Montana that he says has kept him from showing it to any federal agency. And honestly? After hearing his account, it's not hard to understand why. The witness, Ray Thatcher, isn't some weekend hobbyist with a new drone. This is a man who has spent his entire adult life reading landscapes from the air. Timber inventory, wildfire burn assessment, vegetation mapping for federal contracts — the guy knows what elk look like on a thermal sensor at dawn. He knows what bears look like moving through river corridors in early October. He knows what a logging road looks like after heavy equipment has been on it versus when nothing has touched it for 40 years. When he tells you something doesn't match anything in his decades of experience, that carries some serious weight. Here's the setup. In September of 2025, Ray was hired by Clearwater Resource Associates, a forestry consulting firm out of Missoula, to conduct a post-fire vegetation assessment in the Beaverhead-Deerlodge National Forest. The burn unit was a 240-acre lightning-ignited fire on the east flank of Blaine Basin in the eastern Pioneer foothills. Standard contract work. He's done dozens just like it. His assistant on the job was Kira Folsam, a 28-year-old GIS graduate from the University of Montana with her FAA certification, handling the ground station while Ray operated the drone systems. They drove out to the staging area on October 4th, 2025, arriving around 7:45 in the morning. The morning was cold — below freezing overnight, still in the low 30s when they got on site, which is actually ideal for thermal work because cold ambient air increases the contrast between heat signatures and the surrounding environment. The drone Ray was flying was a DJI Mavic 3 Thermal, a dual-sensor system with a standard RGB camera alongside a FLIR Boson thermal core running at 640x512 resolution. For forestry thermal work, he typically flies between 100 and 150 feet above the canopy. At that altitude, you can distinguish individual heat sources on the ground. A smoldering root mass reads differently than a live animal, which reads differently than a sun-warmed rock face. You learn the signatures. The daytime RGB documentation went smoothly. Ninety minutes across three flight legs, the burn unit looked like most small mountain forest fires look three weeks after containment — standing black snags, consumed ground fuel, patches of surviving green timber at the margins. Standard stuff. Then came the thermal pass. Ray launched the thermal drone at approximately 12:45 in the afternoon. For the first 12 minutes, everything looked exactly like every other thermal assessment flight he'd ever run. The burn unit showed three shallow smoldering patches in the root zone, all well below the threshold of concern. He logged them and continued the grid pattern. Then things got interesting. With about 8 to 10 minutes of battery margin remaining after completing the burn unit grid, Ray extended the flight northeast from the burn perimeter, following a tributary drainage up toward a bench of spruce timber at around 7,000 feet. Standard practice in his line of work — extend the flight when there's no operational reason not to, both for the additional documentation value and because the data occasionally has value for adjacent contract work. At approximately 1:00 in the afternoon — and he has the timestamp in the flight log to the second — Ray came over a ridge and began a southwest pass along the upper edge of the tributary drainage. The thermal feed showed spruce and subalpine fir canopy, the canopy temperature reading in the low 30s, the ground below warmer due to earlier sun exposure on the south-facing slope. He spotted what appeared to be three elk at the western end of the bench, their thermal signatures reading as bright warm masses against the cooler canopy, body heat in the range of roughly 102 degrees, exactly what you'd expect from ungulates in cold October temperatures. Then Kira said, "Ray, stop the drone." He stopped the forward flight and put the drone into a hover. She said, "What is that at the left edge of the frame?" Ray rotated the camera to center on the left margin of the image, and what he saw at the upper margin of the spruce stand is what he describes as something that does not look like any of the things he has spent 31 years learning to identify from the air. And here's the part that really got me. Ray mentions a "second layer of footage" — something he didn't understand until he sat with it for three days. That's the part that has kept him from showing it to anyone with a badge or a federal employer. Whatever this man captured, he has been sitting on it. He hasn't shared it with a single agency, a single colleague, or a single person outside of the two individuals who were with him when he first reviewed it. Now, I want to talk about the location for a second because it matters. The Pioneer Mountains of southwestern Montana are not the tallest range in the state — they top out just above 11,000 feet at Torrey Mountain — but the central core is high, rounded plateau terrain with granite and Paleozoic sedimentary rock, open subalpine parkland above the timberline, and dense lodgepole pine and Engelmann spruce below. The range is roughly 35 miles long and 15 miles wide, and the Beaverhead-Deerlodge National Forest covers almost the entire thing. There are two small designated wilderness areas — the East Pioneers Wilderness and the West Pioneers Wilderness — both managed as roadless, both practically unknown outside of Beaverhead County, and a handful of serious backcountry hunters and outfitters who work the elk and mule deer population in there every fall. The upper drainage of Big Sheep Creek, in the western foothills of the Pioneer Range, is about as isolated a piece of ground as you'll find anywhere in southwestern Montana. The lower valley has ranches along it, a county road that follows the creek, scattered BLM ground mixed in with private. But if you go far enough up the Big Sheep Creek drainage northeast toward the Pioneer core, the ranches give out, the Forest Service ground takes over, and the terrain steepens. There's a secondary road that follows the main creek drainage for about nine miles before it dead-ends at a primitive campsite. Beyond that point, you're on foot. The upper drainage, everything above 6,500 feet, is steep, heavily timbered, cut by side draws and tributary creeks, and visited by maybe two or three hunting parties in a given fall, maybe fewer. This is exactly the kind of terrain that does not get looked at very carefully by anyone. And it's exactly the kind of terrain where reports of Sasquatch activity tend to cluster in the Northern Rockies. Southwestern Montana has a long history of sightings — the region sits at the intersection of multiple Indigenous oral traditions describing large, hairy hominids in the high country, and modern witness reports from hunters, outfitters, and Forest Service employees in the Beaverhead and Pioneer ranges have been documented for decades. What makes this footage different — and what makes it worth your time to go watch the full video — is the combination of the witness's professional credibility, the equipment used, and the fact that Ray Thatcher is not someone looking for attention. This is a man who has chosen to stay silent about what he captured because he doesn't know what to do with it. He hasn't tried to sell it. He hasn't gone to the press. He sat with it for three days before he even understood what he was looking at, and he has only shared it with two people outside of himself. The thermal signature he describes at the left edge of the frame, near the upper margin of the spruce stand, is something he says does not match any heat signature he has learned to identify in 31 years of reading landscapes from the air. And the "second layer" of footage — the part he didn't understand until he sat with it — is the part that has kept him from showing it to anyone with a badge or a federal employer. I don't know what's in that footage. But I know that a man with 4,000+ hours of flight time, decades of professional experience reading thermal signatures in mountain terrain, and no apparent motive to fabricate anything has been sitting on something for months that he believes is significant enough to risk his professional reputation by coming forward with it. Go watch the video. See the footage for yourself. And then come back and tell me what you think Ray Thatcher captured in the Pioneer Mountains on the afternoon of October 4th, 2025. Because whatever it is, it has a 63-year-old professional aerial surveyor too spooked to show it to the federal agency that hired him.
