Thule Migration Northward

Timeline

1. c. 1000–1050North Slope of Alaska · AlaskaThule culture originated in the Alaskan region near the Bering Strait; around the early 11th century, people carrying advanced whaling tools and dog-sled technology advanced rapidly eastward along the Arctic coast into the Canadian Arctic.
2. c. 1006–1200Baffin Island and the Queen Elizabeth Islands · NunavutThule people used winter sea ice and summer waterways to cross Arctic islands such as Baffin Island; whaling implements, sled components, and architectural remains unearthed at their sites mark the systematic exploitation of high-latitude marine resources, gradually replacing Dorset culture populations.
3. c. 1100–1300East coast of Greenland · GreenlandThule culture peoples eventually reached the east coast of Greenland, coexisting on the same island with the Viking colony in western Greenland established by Norse people around 982 CE. The Thule people became the direct ancestors of modern Greenlandic Inuit culture, completing the trans-Arctic migration from Alaska to Greenland.
