3,800 year old wetland gardening site discovered in British Columbia
An ancient wetland-gardening site unearthed during a road-building project in British Columbia is as culturally important as any other wonder of the world, says a member of the indigenous group who directed the excavation project.
“This is as important to us as the Egyptian pyramids, or the temples in Thailand, or Machu Picchu,” said Debbie Miller, who works with an archeological consulting firm owned by the Katzie Nation.
Road building crews uncovered a rock platform measuring about 12-square metres made up of flat stones that would have rested several feet underwater four millenniums ago. The distribution of the stones into a pattern of single and double layers, as well as their closely packed arrangement, suggests they were placed deliberately, the study published online in Science Advances found.
The stone “pavement” would have prevented the wapato from penetrating deep into the sludgy, wetland sediment, making it easier for gatherers to use long, sharpened digging tools to locate the buried plant and cut it free.

The site is in Pitt Meadows.
Besides the more than 3,700 pieces of plant material recovered from the site, excavators found more than 150 fire-hardened tips of what are believed to have been digging tools.
The region’s inhabitants are believed to have abandoned the plot about 3,200 years ago, after which researchers discovered the site soon acidified and dried up, Miller said. This, along with sedimentary analysis, suggests First Nations gardening techniques contributed to the overall health of the wetland ecosystem, she added.
Miller said most of the 90-person crew who worked on the archeological project were members of Katzie First Nation and that many were young people who were able to use the project to better connect with their heritage.

“We’ve just walked in the house of the ancestors. It was for many, many of our people an absolute connection to their history, something that they couldn’t have gained in any other way.”
Miller explained that First Nation legend has the character Swaneset going to the other world and returning with a wife, who brought with her the wapato, which became one of the most prevalent resources in the territory.
But the discovery of the wetland garden was also a bittersweet one for the Katzie people, Miller said. Once the excavation was complete, the site was paved over with a public road.
“We brought our ancestors home in our hearts and in our minds and in our conversations with our people,” she said, her voice cracking.
