Around 1000 CE, Norse explorers from Greenland established the first known European settlement in North America at L'Anse aux Meadows on the northern tip of Newfoundland. The archaeological site, discovered in the 1960s, has been carbon-dated to approximately 1021 CE and represents the farthest known extent of European exploration before Columbus nearly 500 years later. Leif Erikson, Bjarni Herjólfsson, and Thorfinn Karlsefni were key figures in these early Norse expeditions to what they called Vinland.
