The Denbigh culture had its origins at least 5000 years ago on the Bering Sea, at places like Capes Denbigh and Krausenstern. From there the flint forms and ideas moved northeastward, deeper into the New World, and westward, back into the Old World of Siberia. The Denbigh ideas flourished in those places long after they had died out on the west coast of Alaska.

The Denbigh flint workers were the first of the race later to be called the People of the Shadow, the People of the Twilight, the Polar Eskimos, the Inuit.
