Built in the early 18th century on the banks of the Saint-François River (Quebec, QC, Canada), the fortified Jesuit mission of Saint-François-de-Sales was an important Abenaki centre during the colonial period. Between 2010 and 2021, archaeological excavations conducted by the Waban-Aki Nation led to the discovery of the mission’s remains at the Fort Odanak site (CaFe-7) in the historical centre of Odanak (Quebec, QC, Canada), and revealed numerous pit features likely used for storage or refuse disposal. As part of a doctoral research conducted in collaboration with the Grand Council of the Waban-Aki Nation and the Abenaki Museum of Odanak, geoarchaeological and archaeobotanical investigations were undertaken on six pit features discovered at the site. Our results provide new information on site formation and occupation over time, and clarify the function and use of the pits studied. They show that the use of traditional pit features persisted until the late 19th century at Odanak, and confirm that maize horticulture was practiced at the site during the 18th and 19th centuries. Together, the methods employed provide a complementary perspective on the daily life of the mission's inhabitants and constitute an innovative approach to the study of Indigenous villages in Quebec.
