From Franklin Pierce University:
Dugout canoes were made and used by Native Americans across eastern North American for thousands of years. A recent study by Franklin Pierce University Professor of Anthropology Dr. Robert Goodby, completed with support from the Franklin Pierce Faculty Development Fund, radiocarbon dated seven dugout canoes recovered from the bottoms of lakes and ponds in New Hampshire and Vermont.
Surprisingly, only two of these, from Fitzwilliam and Unity, New Hampshire, predated European settlement, while the remainder dated between the mid-17th and mid-20th centuries. This showed that, contrary to popular belief, this traditional technology continued in use for centuries after initial European settlement, notably in the upland, rural, and poorer sections of northern New England, where they were used into the 20th century for hunting, fishing, and trapping by people who may have had both Native and European heritage.
They were part of a technological tradition that is neither exclusively indigenous nor exclusively European, but rather a distinctly New England tradition blending influences from both cultures. The results of this research were recently presented in an event sponsored by the Harris Center for Conservation Education and the Mount Kearsarge Indian Museum (https://www.youtube.com/watch?v=FbgOK5vauvw).
