Letter from the Editor
Where on Earth?

Early Americans may have first migrated to the continent on boats along the Queen Charlotte Islands region off the coast of British Columbia, Canada, until a warming period about 10,000 years ago. That warming would have contributed to the severing of the islands from the Canadian mainland. Research suggests that marine habitats for the area about 10,000 years ago were very similar to those of today, shown here. This photo of southern Graham Island in Queen Charlotte Islands is by R.I. Thompson. Find out more about the progression of thinking on human migrations in "The Ice-Free Corridor Revisited" and "Quest for the Lost Land."
