Edible root resources were widely cultivated and consumed by First Peoples throughout North America from the early to mid-Holocene to historic times. In recent decades, archaeobotanists, ethnobotanists, archaeologists, and traditional knowledge-holders have explored and clarified many aspects of root food ecology, production, and exchange. This paper focuses on camas, considered a cultural keystone species across much of western North America because of its high cultural value and influence in defining the cultural identities and land use of resident communities. While historic camas use by First Peoples has been widely documented throughout the Pacific Northwest, the archaeology of camas is little known at coastal sites. This paper presents evidence for a concentration of camas bulbs (Camassia spp.) found in an earth oven complex within an ancient Sts'ailes (Chehalis) village in the Upper Fraser Valley of southwestern British Columbia, Canada. We contextualize this find by exploring the abundant ethnobotanical and ethnohistoric camas literature in order to create a picture of the production and exchange of camas amongst coastal communities of the Northwest Coast. We analyze direct and indirect sources of archaeological data for coastal camas production, which helps us to evaluate questions raised by the presence of this resource 150 km outside of its historical growing range.
To gain insight into pre-contact Coast Salish fishing practices, we used new palaeogenetic analytical techniques to assign sex identifications to salmonid bones from four archaeological sites in Burrard Inlet (Tsleil-Waut), British Columbia, Canada, dating between about 2300–1000 BP (ca. 400 BCE–CE 1200). Our results indicate that male chum salmon (Oncorhynchus keta) were preferentially targeted at two of the four sampled archaeological sites. Because a single male salmon can mate with several females, selectively harvesting male salmon can increase a fishery’s maximum sustainable harvest. We suggest such selective harvesting of visually distinctive male spawning chum salmon was a common practice, most effectively undertaken at wooden weirs spanning small salmon rivers and streams. We argue that this selective harvesting of males is indicative of an ancient and probably geographically widespread practice for ensuring sustainable salmon populations. The archaeological data presented here confirms earlier ethnographic accounts describing the selective harvest of male salmon.
This article examines the social and political implications of the geographically widespread and cross-cultural oral narratives related to the releases of salmon into the rivers of the Pacific Northwest through the destruction of weir-dams. Key themes in these narratives provide insights into indigenous concepts of reciprocity and authority, which in turn reveal dimensions of social organization and intercommunity interactions from a new perspective. These narratives explicitly foreground the inevitable tensions between communities that relied on salmon and also sought to prioritize their own interests, seeking exclusive use of weirs, occasionally to the detriment of other groups. This study illustrates how these narratives convey episodes of contradictory interests, exploitation, social struggle, reconciliation, and a moral charter for communities over a broad area. The analysis also highlights how the messages of these narratives are just as pertinent today as they were in the past.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
