81-Year-Old Reveals 1968 Quebec Cave Rescue With Mysterious Creature

There's a story floating around YouTube right now that has me absolutely riveted, and I think anyone who spends time in the backcountry needs to hear about it. A channel called Beyond The Treeline recently posted a video featuring an elderly woman named Doroth Arseno, an 81-year-old former nurse and search and rescue volunteer from Sept-Îles, Quebec. She's finally breaking her silence on something that happened to her back in September of 1968, and it's the kind of account that makes your skin prickle. Here's the gist: Doroth and her team were called in for what was supposed to be a recovery mission. A woman named Vivian Corivo had been missing for 66 days after disappearing from a family gathering in Haute-Sierre. The provincial authorities were basically writing her off. No one survives 66 days in that kind of boreal terrain without resupply. But survive she did. The team — Doroth, a veteran forester named Fernand, a young constable, and another volunteer named Meline — made their way to a limestone ridge about 40 kilometers inland from the highway. This part of Quebec has unusual geology. Glacial recession left a limestone shelf exposed, riddled with fissures and cave systems that have never been fully mapped. A university team from Laval tried in 1954 and only got two kilometers in before equipment failures and early snow turned them back. When Fernand found the cave entrance, the team noticed something odd. The limestone at the lip had been smoothed along the left edge in a long, even line, from about two and a half feet above the entrance to about four feet up. The smoothing was pale and bright against the older gray rock, meaning it was recent. And the width and height of that smoothed band? The measurements of a grip belonging to something substantially larger than any person. For anyone who's spent time researching reports from the boreal regions of Canada, this kind of physical trace at a cave entrance is exactly the type of evidence that gets documented in the field journals of serious investigators. Smoothed bark on trees, worn rock at den sites, these are the kinds of signs researchers look for when trying to establish habitual use of a location by large unidentified primates. The boreal forest of Quebec and Labrador has a long history of such reports, often from trappers, loggers, and First Nations communities who work deep in the bush. Inside the cave, Fernand noticed impressions in the silt on the gallery floor that stopped him in his tracks. Doroth describes his expression as one she'd never seen in seven years of working beside him. Not fear, but the look of a man rapidly recalculating the parameters of a situation he thought he understood. They found Vivian alive. And when they called out to her, she told them something chilling. She said they needed to understand something before they came any closer. She asked whether they'd seen the marks on the stone at the entrance. When Doroth confirmed they had, Vivian said, "Then you already know I am not alone here." The video cuts off there, but the implications are staggering. Vivian had been living in that cave system for over two months, and whatever had smoothed that limestone was sharing the space with her. She begged the rescuers to leave her there. What makes this account stand out to me is the level of detail and the credibility of the witness. Doroth was a registered nurse of 15 years, a search and rescue volunteer for seven of those years. She explicitly states she understood the difference between what she witnessed and what she supposed. She waited until she was 81 years old to tell this story, and only because her great-niece, a doctoral student in boreal ecology, asked the right questions. The video itself is worth watching for the pacing and the way Doroth tells the story. There's a quietness to her delivery that makes the whole thing feel more real. You can find it on the Beyond The Treeline channel. Stories like this one remind me why the boreal regions of Canada remain some of the most compelling territory for ongoing research. The remoteness, the geology, the history of witness reports from people who actually work the land — it all adds up to a landscape where something could easily remain undocumented for decades. I'll be thinking about Vivian Corivo and that smoothed limestone for a long time.
