Helluland is the name given to one of the three lands, the others being Vinland and Markland, seen by Bjarni Herjólfsson, encountered by Leif Erikson and further explored by Þorfinnr "Karlsefni" Þórðarson around AD 1000 on the North Atlantic coast of North America. As some writers refer to all land beyond Greenland as Vinland, Helluland is sometimes considered a part of Vinland.
According to the sagas
Helluland was said to be the first of three lands in North America visited by Eriksson. He decided against trying to settle there because he found the land inhospitable. He continued south to Markland (probably Labrador) and Vinland (possibly Newfoundland).
The Saga of Erik the Red, 1880 translation into English by J. Sephton from the original Icelandic 'Eiríks saga rauða'.
"They sailed away from land; then to the Vestribygd and to Bjarneyjar (the Bear Islands). Thence they sailed away from Bjarneyjar with northerly winds. They were out at sea two half-days. Then they came to land, and rowed along it in boats, and explored it, and found there flat stones, many and so great that two men might well lie on them stretched on their backs with heel to heel. Polar-foxes were there in abundance. This land they gave name to, and called it Helluland (stone-land)."
"Ragnar brought Helluland's obygdir under his sway and destroyed all the giants there..."
"I will tell you where Ogmund has gone. He has gone into the Skuggifjord (Hudson Strait), it is in Helluland's Obygdir (unihabited regions)... he has gone there because he wishes to escape you. But now you may track him to his house if you wish and see what comes of it."
"Thereupon he (and his son Vignor in separate ships) sailed until they came into the Greenland Sea (which lay between Iceland and Greenland) when they turned south and sailed around the land and to the west... They sailed then until they came to Helluland and laid their course into the Skuggifjord..."
"When they reached the land (which they were seeking in the Skuggifjord) father and son went ashore and walked until they saw a fortified structure very strongly built..."
In ancient Icelandic scholarship
According to a footnote in Arthur Middleton Reeves's The Norse Discovery of America (1906), "the whole of the northern coast of America, west of Greenland, was called by the ancient Icelandic geographers Helluland it Mikla, or Great Helluland; and the island of Newfoundland simply Helluland, or Litla Helluland."
Current scholarly opinion
The Icelandic Saga of Erik the Red and the Greenland Saga characterized Helluland as a land of flat stones (Old Norse: hella). Most scholars agree that Helluland corresponds to Baffin Island in the present-day Canadian territory of Nunavut.
From the testimony of the sagas, the Norse explorers probably made contact with the native Dorset culture of the region, people whom the sagas term skrælings. Historians[who?] suggest the contact had no major cultural ramifications for either side.
Patricia Sutherland, who worked at the Canadian Museum of Civilization until she was fired in 2012, found in the museum's collections yarn collected in archaeological digs on Baffin Island that corresponded to that found in Norse settlements in Greenland, which led her to explore in depth the potential that the Norse had settled on Baffin Island. Over a number of years searching in collections and digging at sites such as Tanfield Valley, she found numerous artifacts, such as tally sticks, signs of iron and bronze metallurgy and whetstones used for sharpening metal tools, and European-style masonry and turf construction, which indicated to her that the Vikings had been on Baffin for an extended period and likely had an established trading relationship with the Dorset natives in the area.
Sutherland's new findings further strengthen the case for a Viking camp on Baffin Island. "While her evidence was compelling before, I find it convincing now," said James Tuck, professor emeritus of archaeology, ... at Memorial University." 
Sutherland and the Helluland Archaeology Project among others[who?] have identified several potential pre-Columbian European archaeological sites including Tanfield Valley, Avayalik at the far north of the Labrador Peninsula, Willows Island at the southern part of Baffin Island, Pond Inlet (Nunguvik) in the far north of Baffin Island. When Sutherland was asked if she might have been fired from the Canadian Museum of Civilization, now the Canadian Museum of History, because her research was out of step with government views of Canadian history, Sutherland agreed.
In 2018, Michele Hayeur Smith of Brown University, who specializes in the study of ancient textiles, wrote that she does not think the ancient Arctic people, the Dorset and Thule, needed to be taught how to spin yarn "It's a pretty intuitive thing to do." Journal of Archaeological Science, August 2018:
". . . the date received on Sample 4440b from Nanook clearly indicates that sinew was being spun and plied at least as early, if not earlier, than yarn at this site. We feel that the most parsimonious explanation of this data is that the practice of spinning hair and wool into plied yarn most likely developed naturally within this context of complex, indigenous, Arctic ﬁber technologies, and not through contact with European textile producers. [. . .] Our investigations indicate that Paleoeskimo (Dorset) communities on Baffin Island spun threads from the hair and also from the sinews of native terrestrial grazing animals, most likely musk ox and arctic hare, throughout the Middle Dorset period and for at least a millennium before there is any reasonable evidence of European activity in the islands of the North Atlantic or in the North American Arctic."
William W. Fitzhugh, Director of the Arctic Studies Center at the Smithsonian Institution, and a Senior Scientist at the National Museum of Natural History, wrote that there is insufficient published evidence to support Sutherland's claims, and that the Dorset were using spun cordage by the 6th century. In 1992, Elizabeth Wayland Barber wrote that a piece of three-ply yarn that dates to the Paleolithic era, that ended about 10,000 BP, was found at the Lascaux caves in France. This yarn consisted of three s-twist strands that were z-plied, much like the way a three-ply yarn is made now, the Baffin Island yarn was a simple two-ply yarn. The eight sod buildings and artifacts found in the 1960s at L'Anse aux Meadows, located on the northern tip of Newfoundland, remains the only confirmed Norse site in North America outside of those found in Greenland.

In fact, Fitzhugh thinks the cord at the centre of Sutherland’s “eureka” moment is a Dorset artifact. “We have very good evidence that this kind of spun cordage was being used hundreds of years before the Norse arrived in the New World, in other words 500 to 600 CE, at the least,” he says.
