Quantifying the defensiveness of defended sites on the Northwest Coast of North America

Defensive architectural features are used to evaluate the scale and pervasiveness of conflict in antiquity around the world, but in the archaeology of conflict on the Northwest Coast, the relationship between physical landscapes, built defensive features and warfare has never been tested using quantifiable measures. We argue here that the syntax of biomechanical control, reflecting the universality of the parameters of the human body, is inherent in architectural analyses of conflict, and develop an index of defense (DI) based on commonly invoked constituent measures of defensiveness. The DI is represented in a single value, derived from four individual measures (visibility, elevation, accessibility and area), each with constituent variables. We test this quantitative measure using a sample of identified defensive and non-defensive sites on the Northwest Coast of North America in order to evaluate this system of quantifying the contribution of site location and architectural features to the overall defensiveness of communities and discuss some of the implications of this measure on interpreting the role of conflict on the Northwest Coast.     

Clam growth-stage profiles as a measure of harvest intensity and resource management on the central coast of British Columbia

Examination of growth-stage profiles of shells from nine Northwest Coast shell midden sites shows a majority of senile-stage shells at longer-term residential sites and a majority of mature-stage shells at shorter-term encampments. This pattern indicates less intensive harvest in the vicinity of residential sites, which is consistent with management and conservation of resources for anticipated future needs. Consideration of environmental and taphonomic factors does not account for the observed inter-site variability. Shellfish conservation in the vicinity of residential sites is evident for the period of the past 7000 years.     

Ships on Hero Stones from the West Coast of India

Hero stones have been erected since early times to remember those who died in battle, and have been reported from various provinces of India. Most show land-battles, but those in the Archaeological Museum, Goa and Eksar in Mumbai show naval warfare. The Old Goa stones belong to the Kadambas who ruled Goa from 950–1300 AD. The Eksar stones to the reign of king Bhoja of Malwa in 1020 AD. Similar hero stones with boat motifs of the 18th to 19th centuries AD have been reported from Aramda in Gujarat. This paper examines these stones and assesses their significance for the maritime history of India.

Tracking Fish and Human Response to Earthquakes on the Northwest Coast of Washington State,USA: A Preliminary Study at Tse-whit-zen

Evidence of large earthquakes occurring along the Pacific Northwest Coast is reflected in coastal stratigraphy from Oregon to British Columbia, where there also exists an extensive archaeological record of Native American occupation. Tse-whit-zen, a large Native American village dating between ～2800 yrs BP and the historic era, located on the Olympic Peninsula of Washington State, was excavated with exceptionally fine stratigraphic control allowing for precise comparison of these natural and cultural records. Here we report on the ～10,000 fish remains from one 2 × 2 m excavation block; this assemblage spans the timing of one seismic event, allowing study of changes in relative taxonomic abundance through time that may coincide with earthquakes or other environmental changes. Results indicate a wide variety of fish taxa were used throughout the dated occupation. Comparisons of fish use before and after one earthquake event shows a decline in salmon (Oncorhynchus sp.) and an increase in herring (Clupea pallasii), shifts consistent with earthquake-related habitat loss. This serves as a pilot study for a large-scale collaborative project that is drawing on the range in animal types (invertebrates, mammals, birds, and fishes) to assess human response to gradual and abrupt environmental change at Tse-whit-zen.     

Hydraulic engineering and irrigation agriculture in the Moche Valley,Peru: c. A.D. 1250–1532

This paper examines the hydraulic properties (i.e. velocity and discharge) of the main late prehistoric canals of the Moche Valley. Velocities, estimated from excavated canal sections using the Manning flow equation, are compared to tables of maximum permissible velocities and reveal that canals were constructed to transport water efficiently, but that on gradients steeper than 1:100 the Chimu and Inca engineers were unable to transport large discharges without severe erosional problems. Discharge estimates are compared with modern field requirements, using a known ethnographic watering cycle. This demonstrates that in almost every instance the channel size was of the same order of magnitude as that predicted from the requirements. The construction of the Inter-valley canal to bring water to the state lands in Moche was a technological disaster.
