Retired Mexican Firefighter Shares Lifelong Bigfoot Encounters in Cloud Forests

There's something about a witness who spent 26 years working in the wilderness that just hits different. When someone like that comes forward with not one, but multiple encounters spanning decades, you know it's worth paying attention to.
A video recently surfaced on YouTube featuring Aurelio Ríos Zaragoza, a 68-year-old former forest firefighter who spent over two decades working in the Huasteca Potosina region of San Luis Potosí, Mexico. What he shares in this account is the kind of testimony that makes you lean in a little closer.
Aurelio describes himself as someone who knows those mountains intimately. Every canyon between Xilitla and Aquismón, every deep chasm where cold air rises from the depths of the Earth, the sound the wind makes before it shifts, the smell the forest gives off three days before it begins to burn. When someone with that level of experience tells you something extraordinary happened, it carries weight.
His first encounter dates back to 1987, when he was just 31 years old and volunteering with his community to fight a wildfire in the highlands. While digging a firebreak with about 15 other men, he caught movement out of the corner of his eye. What he saw wasn't a deer fleeing the flames. It was something tall, walking upright on two legs, moving through the trunks with purpose. Broad shoulders covered in dark, dense hair matted by the forest's humidity. For a half-second, it turned its head, and Aurelio saw eyes that were calculating, deciding, thinking. Not an animal's face.
He kept quiet that day. But that night, wiping ash from his face, he remembered his grandmother, a Tenek woman from a town near Tancanhuitz, and the stories she used to tell about the "masters of the mountain." For the first time in his life, he didn't dismiss them as old wives' tales.
The Tenek people, also known as the Huastecs, have inhabited this region for thousands of years, long before the Aztecs arrived. Their language doesn't resemble any of the surrounding ones, and their oral traditions speak of beings in the high parts of the sierra, in the ravines where the cornfields don't reach, who were the true masters of that forest. One had to ask permission before going deep, leave something, speak with respect. These weren't campfire stories meant to frighten children. They were treated like facts of life, like the weather or the harvest.
Over the years, Aurelio began noticing things. Tracks in the mud on the banks of high streams after the rains, barefoot prints with five toes, but the length of his forearm, sunk deep into the mud with a weight no man in the region had. He measured them once with a stick. They weren't a trick of the light.
On watch nights in the high country, there's a moment after midnight when the forest goes silent in a way that isn't natural. The insects fall quiet, the night birds stop moving, and in that silence, sometimes you would hear a knock. Just one, dry, like wood hitting wood, coming from very far away, from deep in a ravine. And after a while, from another ravine, also very far off, another knock in response. The veteran brigade members, those who had been there as long as he had or longer, would stop talking when they heard that. Nobody said a word.
Then there was the smell. A deep, damp earth scent mixed with something musky, warm, heavy. Not unpleasant, but alive, like a stable, yet cleaner, more like the forest itself. It would appear suddenly on a stretch of path and vanish a few meters later, as if something had passed by just moments before.
His second close encounter came in 1996, already wearing a uniform and carrying a radio as part of the formal brigade. Walking alone on a reconnaissance patrol above Xilitla during the dry season, the smell hit him head-on, stronger than ever. He stopped, remembering his grandmother's advice to wait, not move forward. On the other side of a patch of ferns, about 12 to 15 meters away, something moved and straightened up. It had been crouching, doing something on the ground, and when it sensed him, it stood slowly to its full height, which was much more than his own.
This time, in the morning light, he saw the whole face. A heavy forehead protruding over the eyes, a wide flat nose, a strong jaw, but the eyes were what held him there. Dark, deep, and looking at him with an attention that wasn't that of an animal measuring whether he was a threat or food. It was the attention of someone deciding what to think of him.
They stared at each other for what felt like an eternity, though it was probably only seconds. Aurelio describes the fear he felt as different from anything a jaguar or snake could produce. It was the sensation of being in front of something much greater, in a sense that went beyond just size.
What makes this account particularly compelling is the framing Aurelio provides at the beginning. He mentions that in the autumn of 2004, he witnessed something he'd never seen in 26 years on the crew. The forest itself appeared afraid. And what lived in those highlands, what had been there since long before humans arrived, decided to leave. Not from fire, not from people, but from something else. Something that arrived in those hills and made even the masters of the forest want to be anywhere else.
The Huasteca Potosina is a fascinating region for anyone interested in this subject. The cloud forests, the moss-laden oaks, the ferns the size of a man, the sinkholes plunging hundreds of meters into the rock, it creates an environment where something could remain hidden for centuries. Mexico has its own rich tradition of sightings, with reports spanning various indigenous cultures who have long spoken of hairy giants dwelling in remote mountainous regions.
Aurelio's account is one of those rare testimonies that comes from someone whose entire life was spent in those mountains, someone who learned to read the forest the way most of us read a book. His encounters weren't the result of a single camping trip or a curious hike. They were accumulated over a lifetime of presence in the wilderness.
This is definitely worth setting aside some time to watch. The way Aurelio tells his story, with the patience and detail of someone who has carried these memories for decades, draws you in completely. You can find it on the YouTube channel El Ser Gigante, and trust me, you'll want to hear the rest of what he has to say.
