Using ancient DNA identification and osteometric measures of archaeological Pacific salmon vertebrae for reconstructing salmon fisheries and site seasonality at Dionisio Point,British Columbia

Determining the diversity of salmon species represented in archaeological contexts is critical to understanding patterns of salmon harvesting and consumption, storage practices and seasonal patterns of resource exploitation by precontact peoples of the Northwest Coast. We present species determinations generated for salmon vertebrae from the Dionisio Point site (DgRv-003) in coastal southwestern British Columbia, a well-preserved village site that dates to between 1500 and 1300 cal BP. Molecular species identification was possible for 70 Pacific salmonid vertebral elements recovered from one excavated plankhouse at the site. Coupled with osteometric measures, we determine that residents of the plankhouse fished primarily for chum, sockeye and pink salmon, with a lesser emphasis on chinook, coho and steelhead. These results indicate a diverse fishery that likely occurred between July and December, suggesting a mid summer through winter season of occupation for the village.     

Recovering the Forgotten Woodland Mound Excavations at Garden Patch (8DI4)

Forty-five years ago Timothy Thompson excavated at two of the six mounds at the Garden Patch site but results were never reported. We assembled data from Thompson's work and enhanced them with new test pits at Mound IV and re-excavation of a Mound V trench. Mound IV is a natural sand ridge where a village was established early, by the second century A.D. Mound V began as a naturally elevated platform for at least one burial and associated structure during the fourth century A.D. and was then covered by lenses of shell and sand. The construction sequence of Mound V resembles other mounds in the region. These results help illuminate the functions and depositional histories of mounds within Woodland multi-mound centers of the coastal plain while also demonstrating an effective approach to balancing stewardship and new excavations.     

Temperature‐dependent Li isotope ratios in Appalachian Plateau and Gulf Coast Sedimentary Basin saline water

Lithium (Li) concentrations of produced water from unconventional (horizontally drilled and hydraulically fractured shale) and conventional gas wells in Devonian reservoirs in the Appalachian Plateau region of western Pennsylvania range from 0.6 to 17 mmol kg^?1, and Li isotope ratios, expressed as in δ⁷Li, range from +8.2 to +15‰. Li concentrations are as high as 40 mmol kg^?1 in produced waters from Plio‐Pleistocene through Jurassic‐aged reservoirs in the Gulf Coast Sedimentary Basin analyzed for this study, and δ⁷Li values range from about +4.2 to +16.6‰. Because of charge‐balance constraints and rock buffering, Li concentrations in saline waters from sedimentary basins throughout the world (including this study) are generally positively correlated with chloride (Cl), the dominant anion in these fluids. Li concentrations also vary with depth, although the extent of depth dependence differs among sedimentary basins. In general, Li concentrations are higher than expected from seawater or evaporation of seawater and therefore require water–mineral reactions that remove lithium from the minerals. Li isotope ratios in these produced waters vary inversely with temperature. However, calculations of temperature‐dependent fractionation of δ⁷Li between average shale δ⁷Li (?0.7‰) and water result in δ⁷Li_water that is more positive than that of most produced waters. This suggests that aqueous δ⁷Li may reflect transport of water from depth and/or reaction with rocks having δ⁷Li lighter than average shale.     

Revisiting nineteenth-century U.S. interventionism in Central America: capitalism,intrigue, and the obliteration of Greytown

In October 2016 the Congressional Research Service published its latest version of “Instances of Use of United States Armed Forces Abroad.” One of the “instances” occurred in 1854, and the entry reads in its entirety: “Naval forces bombarded and burned San Juan del Norte (Greytown) to avenge an insult to the American Minister to Nicaragua.”¹1. Torreon, Instances of Use of United States Armed Forces Abroad, 1798–2016, 4.View all notes The following article posits that Greytown was not destroyed to avenge an insult to an American diplomat. Rather, two groups of prominent American businessmen used this and related events and their antecedents as pretexts to enlist the federal government in destroying Greytown. One group, representing a U.S.-owned isthmian steamboat company, sought to seize the port of Greytown as a private fiefdom; the other wanted it as the prospective capital of a new colony based on a huge, dubious land grant they owned.     

Trace element and Pb isotope provenance analyses of native copper in northwestern North America: results of a recent pilot study using INAA,ICP-MS,and LA-MC-ICP-MS

Several indigenous groups in northwestern North America used native copper prior to EuroAmerican contact. The Arctic, Subarctic, and Northwest Coast culture areas all have archaeological finds and geological sources of native copper. The copper-rich region of south-central Alaska and southwestern Yukon has often been credited as the source of archaeological native copper found on the Northwest Coast despite the presence of native copper sources further south. This paper presents the results of a pilot study using INAA, ICP-MS, and LA-MC-ICP-MS to assess the potential for native copper provenance research in Alaska and the Yukon Territory. Discrete native copper sources could be distinguished from one another intra-regionally. Difficulties associated with future native copper provenance research in northwestern North America are discussed.     

From Pleistocene Mariners to Complex Hunter-Gatherers: The Archaeology of the California Channel Islands

California’s Channel Islands were home to some of the most distinctive Native American peoples along the Pacific Coast. Never connected to the mainland during the Quaternary, the Channel Islands have an impoverished terrestrial flora and fauna, but some of the richest and most productive marine environments in the Americas, including diverse kelp forest, intertidal, and offshore marine habitats. Native Americans occupied the Channel Islands for roughly 13,000 calendar years until the early nineteenth century, providing one of the longest and best preserved records of maritime hunter-gatherers in the Americas. We provide an overview and analysis of Channel Islands archaeology, from the relatively mobile peoples who colonized the islands during the Late Pleistocene to the complex hunter-gatherers documented by early Spanish explorers. Our analysis demonstrates the importance of Channel Islands archaeology for enhancing knowledge on a number of broad anthropological issues, including coastal and aquatic adaptations, seafaring, cultural complexity, trade and exchange, and ancient human impacts on the environment.     

Archaeological Survey of Dynamic Coastal Landscapes and Paleoshorelines: Locating Early Holocene Sites in the Prince Rupert Harbour Area,British Columbia,Canada

We present and test a predictive archaeological survey model that targets early Holocene paleoshorelines in the Prince Rupert Harbour area using LiDAR bare earth digital terrain models and a 15,000-year reconstructed history of relative sea level change. Despite a century of archaeological research in the study area, no sites dating earlier than 6000 cal b.p. had been identified prior to our research. Our field survey identified three early Holocene sites associated with paleoshorelines 7–10?m above current sea level (masl). These locations demonstrate repeated use through the Holocene even as shoreline position changes. We discuss these new data in relation to the early Holocene archaeological record from the rest of the northern Northwest Coast and suggest that the region was ubiquitously occupied by this time and that the lack of recorded early Holocene sites in some areas is likely a result of survey and preservation bias, rather than historical reality.     

Continuity Amidst Change: Village Organization and Fishing Subsistence at the Dionisio Point Locality in Coastal Southern British Columbia

Shifts over time in faunal representation in Northwest Coast archaeological sites have been viewed as reflecting changes in economic organization and social complexity. We use fish faunal data from the Parry Lagoon Midden (site DgRv-006) in the Salish Sea region of coastal southwestern British Columbia, Canada, to evaluate the relationship between change in subsistence strategies and community organization. We describe and compare fish assemblages recovered from a shell midden generated by habitation at two sequentially occupied village sites. The lower midden layers include faunal remains derived from the Marpole Period plankhouse village occupation at site DgRv-003 (1500 to 1300 cal BP), while the upper layers were generated during the occupation of a Late Period plankhouse within site DgRv-006 (1000 to 600 cal BP). We compare the two faunal records to ascertain if subsistence re-organization accompanied the social change associated with abandonment and later re-establishment of a village in the Dionisio Point Locality. Results indicate continuity of a diverse fishing economy for the two occupations, and therefore across the Marpole to Late Period transition. This study adds to the recent trend in Northwest Coast archaeology to reconsider the long-standing view that social and subsistence change necessarily occurred in tandem.     

A chicken on every pot: curious avian ceramic vessels on the Gulf Coast

ABSTRACT

In a recent examination of bird effigy vessels from the north-central coast of the Gulf of Mexico, one remarkable species identified appears to be Gallus gallus domesticus, or the chicken. Examples of small ceramic rooster heads sporting dramatic, single combs and short beaks may be indirect evidence of contact between native coastal peoples and Spanish explorers in the early decades of the AD 1500s. The particular socio-cultural conditions that would have made possible the introduction of these decidedly non-native birds into the repertoire of Native American potters in the protohistoric era are explored.     

A humerus story: Albatross element distribution from two northwest coast sites,North America

The distribution of the skeletal elements of albatross from the Maple Bank site is compared with those for ducks and gulls at that site and others on the northwest coast of America. The element distribution was very different between species and between sites. The proportions of albatross bones found suggest that there was a cultural reason for the elements present, probably the curation of wing bones for toolmaking and other uses. © 1997 John Wiley & Sons, Ltd.
