While researching the question What are the earliest known origins of Sasquatches in Native American culture in the Americas? I found several sites claiming that Leif Ericson recorded an encounter with sasquatch in 968 AD. For example, the Sasquatch Chronicles Blog:

The oldest account of Bigfoot was recorded in 986 AD by Leif Ericson and his men. During their first landing in the New World, the Norsemen wrote about manlike beasts that were “horribly ugly, hairy, swarthy and with great black eyes.”
Among his accounts, Leif told of seeing huge hairy men who towered over him and his men. The “huge hairy men”, according to Leif, lived in the Woods and had a rank odour and a deafening shriek. It should be noted that Leif Ericson and his men describe huge manlike beasts that were loud and foul-smelling and clearly distinct from native peoples. Apparently, Leif had several sightings of the “huge hairy men” before departing the island.
They called the creature “Skellring”. People believe that the creature “Skellring” is what we know today as Bigfoot. This is the earliest recorded encounter with Bigfoot, or Sasquatch.
The Greenlander's journeys to North America are known mainly from two Sagas: the Grænlendinga saga ("The Saga of the Greenlanders") and the Eiríks saga rauða ("The Saga of Erik the Red"), plus some mentions in other sources . The Skrælings are thus not the inventions of one writer. However, they were not mystical beasts, but ordinary people: both the Thule people (ancestors of modern Inuits) on Greenland as well as inhabitants of Northern America were called Skraelings by the Norse.

There is a description of the Skraelings in the Saga of Eric the Red:

They were short men, ill-looking, with their hair in disorderly fashion on their heads; they were large-eyed, and had broad cheeks.
The Icelandic saga database.: The Saga of Erik the Red, Chapter 10. Translation by J. Sephton.

As you can see, only the hairy bit can be said to fit, and other details are the exact opposite of your quote, or totally absent. The Saga also tells how two Skraelings came to live on Greenland for one winter. (The Saga of the Greenlanders gives a more violent account; there the two peoples never learn to talk to eachother, but it's still clear that the Skraelings are human).

The word Skraeling seems to survive in modern Icelandic, meaning Barbarian. One suggested, but by no means sure, etymology of it derives it from a word for shouting, which at least somewhat fits a part of the description.
So did he and his men encounter Sasquatch ? The descriptions and Info sounds very possible Or were they just primitive wild native men ?
Bigfoot Explorers (2025)

Bigfoot Explorers follows cryptid researcher Daniel Benoit and his team as they venture into dense forests, secluded lakesides, and remote backwoods in pursuit of one of the world's most enduring legends. Each episode documents their journey as they set up base camps, review witness accounts, and prepare for the unknown.

The series begins with Daniel introducing viewers to the investigators: David and Melissa Lester, Drew Barker, and John and Mary Nicely. Together they map out hotspots where reports of sightings, strange noises and unexplained tracks have been documented for decades. With cameras rolling, they pack their gear and trek into wilderness where human presence is scarce.

Early episodes highlight their methodology. By day they scour riverbanks and ridgelines for broken branches, footprints, and hair samples. At night they set up thermal cameras and listening devices, recording eerie vocalizations that echo through the trees. The team reacts in real time, debating whether the evidence points to wildlife or something far stranger.

As the season progresses, the expeditions intensify. Viewers witness late-night stakeouts in total darkness, tense walks through fog-covered trails, and the sudden discovery of massive tracks that dwarf human footprints. In one chilling sequence, the group is startled by movement in the brush just beyond the reach of their flashlights, a reminder that they may not be alone.

The investigators balance their scientific approach with the emotional weight of chasing a legend. They interview locals whose lives were changed by encounters in the woods, from hunters who abandoned lifelong grounds to families who refuse to camp outdoors. These testimonies are woven together with the team's on-the-ground research, creating a layered narrative that is equal parts documentary and survival thriller.

By the end of the season, the Bigfoot Explorers have gathered a library of audio, video, and physical evidence. Yet the deeper question remains: have they uncovered proof of a hidden species, or have they stepped into a mystery that cannot be solved? The series closes by inviting viewers to draw their own conclusions, while reminding them that the search for Bigfoot is far from over.

Bigfoot Explorers is a series about discovery, belief, and the razor's edge between myth and reality. It is an episodic chronicle of investigators who risk safety and sanity to reveal what lurks in the forests, a journey that blurs the line between documentary, horror, and the unshakable power of folklore.
