The fruit of their labour: plants and plant processing at EeRb 140 (860±60 uncal B.P. to 160±50 uncal B.P.), a late prehistoric hunter-gatherer-fisher site on the southern Interior Plateau, British Columbia, Canada

Abstract.

Palaeoethnobotanical analysis of Late Period contexts (860±60 uncal B.P. to 160±50 uncal B.P.) at the site of EeRb 140, indicates that it probably served as a seasonal work area, utilised during the mid to late summer by the residents of an adjacent pit-house winter village. Food processing was evidently the primary plant-related activity at this open-air hunter-gatherer-fisher site on the British Columbia Plateau in Canada. One feature appears to have functioned as both an open hearth for the drying and preservation of berries and as a pit-oven, possibly for preparing foods for immediate consumption. Comparisons of the archaeobotany of EeRb 140 with Plateau ethnographies suggest that women's task group activities are represented here. Most significantly, the identification of a specialised plant-processing site in such close proximity to a winter village contrasts strongly with existing ethnoarchaeological models for the British Columbia Plateau and introduces a type of site not previously identified archaeologically in this region.
