Abstract Starry flounders, prickly sculpins and other resident fishes were captured in the Lower Fraser River in the summers of 1987, 1988 and 1989. Control fish were taken from the estuary of the uncontaminated Homathko River on the B.C. coast in 1987 and 1988. The fish were analysed for chlorophenols, chloroguaiacols and PCBs. The residues most commonly detected were PCBs, tetra-and pentachlorophenol. Fish from the Main Arm contained PCBs that resembled Arochlor 1248 whereas those from the North Arm contained PCBs that resembled a mixture of Arochlors 1254 and 1260. Chloroguaiacol uptake was greater in flounders than in other species. Although PCBs appear to have declined markedly in the Lower Fraser from values published in the early 1970s, there is a need to measure the coplanar fraction to understand their toxic significance to the food chain. Tetra- and pentachlorophenol have declined following a change by industry to the use of alternative sapstain prevention treatments.

Were the ancient Coast Salish farmers? Conventional anthropological wisdom asserts that the ethnographically known communities of the Northwest Coast of North America were “complex hunter-fisher-gatherers” who lacked any form of concerted plant food cultivation and production. Despite decades of extensive ethnobotanical and paleoethnobotanical study throughout the Pacific Northwest demonstrating the contrary, this “classic anomaly” is still a cornerstone of anthropological and archaeological canons. The recent discovery of a spectacularly preserved wetland wapato (Indian potato, Sagittaria latifolia) garden, built 3,800 years ago in Katzie traditional territory near Vancouver, British Columbia, has helped recast this picture, alongside evidence for other forms of resource management practiced by Northwest Coast peoples. This article examines “origins of agriculture” stories from three distinctive perspectives: Coast Salish Katzie people who cultivated wapato for millennia; settlers who colonized the Fraser River Delta historically, bringing with them their own ideas about what constitutes farming; and archaeologists, who are challenged by these data to reevaluate their own understandings of these cultural constructs. These perspectives have critical bearing on the historical appropriation of lands and waterways by settler communities in British Columbia as well as contemporary questions of sovereignty and stewardship in this region and well beyond.

The Way

Semi-Subterranean houses with an entrance through the roof are a well known feature of the interior of British Columbia, having been described for the Thompson, the Chilcotin, the Shuswap and others of the upper Fraser River valley. They have, in fact, an even wider distribution east of the Coast and Cascade Ranges, extending south over the Plateau and into northern California. Although this type of dwelling existed among the Aleuts, it appears that the coastal people to the south of them, even in Alaska, were either unfamiliar with the pattern or rejected it in favor of others. Sporadically, along the Pacific Coast all the way from California to Bering Sea, house floors were excavated to varying depths, sometimes even to two levels; but, everywhere, the houses characteristically lack the roof entrance and, except for sweathouses in the south and Bering Sea Eskimo dwellings in the north, even the idea of an earth covering is absent. In view of this fundamental divergence, it is interesting that subterranean structures do appear in several places on the coast of British Columbia.
