Which North American regions did Leif Erikson probably reach?

According to the Grænlendinga saga (“Saga of the Greenlanders”), Leif Erikson explored several regions in North America while sailing west from Greenland around 1000 CE. He named these areas based on their geographical features:

• Helluland (“Land of Flat Rocks”): Identified as the Frobisher Bay area or possibly Cape Chidley on the northern tip of Labrador.
• Markland (“Land of Forests”): Likely the central coast of Labrador.
• Vinland (“Land of Wine”): The southernmost region he reached, possibly surrounding the Gulf of Saint Lawrence.

Archaeological evidence confirms that Norse voyagers reached North America, specifically at L’Anse aux Meadows on the northern tip of Newfoundland. This site, dated to approximately 1000 CE, serves as proof of a Viking presence in the region centuries before the arrival of Christopher Columbus. While some historical narratives suggest they may have traveled as far south as Maine or Rhode Island, these locations remain speculative compared to the confirmed settlement in Newfoundland.12
