BRITISH COLUMBIA, CANADA—Live Science reports that a prehistoric garden has been found on Katzie First Nation territory, located to the east of Vancouver. Archaeologist Tanja Hoffmann of the Katzie Development Limited Partnership and Simon Fraser University led the excavation of the 3,800-year-old waterlogged site. It yielded more than 3,700 whole and fragmented wapato plants, which grow in wetlands and produce starchy roots similar to potatoes. The plants were not domesticated, but Hoffmann said they were grown in a plot set over a pavement of tightly packed, uniformly sized rocks, which would have made it easier to harvest the tubers. Some 150 wooden harvesting tools were also recovered. To read more about archaeology in Canada, go to “A Removable Feast.”
