Exploring Stó:Lō-Coast Salish Interaction and Identity in Ancient Houses and Settlements in the Fraser Valley, British Columbia

Social scientists recognize a complex and iterative relationship between the built environment and social identities. Here, we explore the extent to which household and settlement remains may be used as archaeological correlates of collective identities among the Stó:lō-Coast Salish peoples of the Fraser River Valley. Using data from six recently tested archaeological sites we begin with the household and explore expressions of identity at various social-spatial scales. The sites span the period from 4200 cal B.C. to the late A.D. 1800s and include settlements with semi-subterranean houses of different forms as well as aboveground plank houses. Across this timeframe we see both change and continuity in settlement location, layout, size, and house form. Our data suggest that although group identities have changed over the millennia, selected social units have persisted through many generations and can be linked to present-day identities of the Stó:lō-Coast Salish.

Television as a Social or Solo Activity: Understanding Families' Everyday Television Viewing Patterns

Over four days, a researcher recorded the at-home activities of 30 families at 10-min intervals. Television viewing was the second most frequently observed activity for parents and the most frequently observed activity for children. Most television was watched in common areas of the home and in the presence of at least one other person, with the most common viewing configuration involving both parents and at least one child. When parents pursued another activity in conjunction with TV viewing, that activity was most likely to be in-person social interaction. In contrast, children were more likely to watch TV in bedroom spaces and were more likely to pair TV viewing with other leisure activities. In families with TVs in a childs bedroom (about ½ of the families), children were especially likely to watch TV alone and in non-common areas of the home. The results indicate that parents tend to engage in television viewing as a social activity, but that children may be more likely to be solo viewers.

FIELDWORKER EXPERIENCE AND SINGLE-EPISODE SCREENING AS SOURCES OF DATA RECOVERY BIAS IN ARCHAEOLOGY: A CASE STUDY FROM THE CENTRAL PACIFIC NORTHWEST COAST

Despite increasing concern with the effects of archaeological data recovery methods on the types and quantity of objects extracted from the material record, archaeologists rarely discuss recovery biases attributable to the most basic excavation procedures. In this study I examine how several factors, including variable artifact identification skills, can affect artifact recovery rates in the field. Data from household-level investigations at the Stó:lō (Coast Salish) village of Welqámex (DiRi 15) are presented to show how interobserver variation can compromise interpretations of past behavior when opportunities for artifact recovery are limited to observations at the excavation unit and single-episode (field-only) sieving. Laboratory sorting of screen residue retained in 3.2-mm (one-eighth-inch) mesh sieves is shown to account for the recovery of as much as 87.5 percent of lithic artifacts and nearly 90 percent of archaeofaunal remains. Rates of artifact recovery in the field are highly variable among excavation crews working at Welqámex, and I argue that the application of correction factors is inappropriate unless the magnitude of recovery bias can be measured for specific excavation teams and particular depositional contexts. The results of this study further highlight the importance of documenting and mitigating the unintended effects of methodological decisions on archaeological assemblages.

THERMALLY MODIFIED ROCK: THE EXPERIMENTAL STUDY OF "FIRE-CRACKED" BYPRODUCTS OF HOT ROCK COOKING

Despite its ubiquity in residential middens at many North American archaeological sites, thermally modified rock (TMR) is among the least studied elements of the archaeological record. TMR assemblages, however, may provide key insights into routine cooking practices, patterns of refuse disposal, and midden formation processes. This article outlines the results of experimental research aimed at understanding the conditions by which TMR assemblages were created in residential settlements in the Pacific Northwest. We present baseline data addressing the thermal properties of the hearth, the rate and circumstances of cobble fracturing, the extent to which different kinds of cobbles break when exposed to heat for varying durations, and the effectiveness of hot cobbles at achieving cooking temperatures.

The Pocket Penetrometer

Abstract The identification of earthen house floors or living surfaces during archaeological field investigations can be hampered by the scale of excavation, variable fieldworker experiences, and any number of site formation processes. Furthermore, although time- and context-sensitive sampling protocols (e.g., those required of macrobotanical and microartifact data collection) rely on in-the-moment identifications of floors, strong empirical evidence for the presence of house floors often comes well after the field season has concluded. Pocket penetrometers—inexpensive instruments that measure the compaction strength of soil—can lend empirical support to decisions about sampling procedures during onsite investigations. In this study, we present findings from the analysis of 4,463 penetrometer readings recorded during the excavation of residential and non-residential architecture at Welqámex, a Stó:lō-Coast Salish settlement in southwestern British Columbia. We show how pocket penetrometer data reveal quantifiable differences in the compaction of floors and other cultural deposits. We argue that compaction measurements can provide an additional line of data (ratio scale) to affirm or challenge onsite interpretations of stratigraphy based on other tactile and observational data, particularly as such interpretations pertain to surfaces expected to have been exposed to recurrent foot traffic
