Rock Fortifications: Archaeological Insights Into Precontact Warfare and Sociopolitical Organization Among the Stó:lō of the Lower Fraser River Canyon, B.C.

Whether or not traditional centralized leadership existed among the central Coast Salish of the Gulf of Georgia-Puget Sound Regions is a topic of ongoing interest and debate among archaeologists, social anthropologists, ethnohistorians, and Aboriginal communities. Recent findings in the lower Fraser River Canyon of British Columbia of a unique class of archaeological site—rock fortifications, newly identified on the Northwest Coast—present an opportunity to address this discussion. Description of these features and analysis of their situation within the physical and social landscapes of the Fraser Canyon provides insight into the nature of Stó:lō warfare and defensive strategy. I propose the existence of a multivillage defensive network aimed at regulating access to the entire “Canyon watershed” rather than simply defending individual settlements. I present a “corporate family group” model of sociopolitical organization through which this defensive system operated—representing a minimum level of intercommunity governance traditionally known to the Sto:Lō of the Gulf of Georgia Region. This proposition provides an alternate view to the long-held belief that individual households were the traditional centers of economy, and by extension, of political authority among the Aboriginal peoples of the Northwest Coast. These results affect the current understanding and reconstruction of traditional expressions of Stó: Lō identity engrained in sociopolitical organization.
