Maya and Climate has affected the vitality of many different societies in past, as shown by numerous records across globe throughout human history. One most obvious spectacular examples this is from Classic civilization, whose advanced culture left highly detailed all aspects their existence between 300 1000 C.E. Kennett et al. (p. 788 ; see cover) present a climate record derived stalagmite collected cave Belize, midst settlement. The fine resolution precise dating allows changes...
We evaluate existing radiocarbon dates at sites containing Haskett stemmed projectile points, present 12 new from 5 components 4 sites, and model the age of points in a multiphase Bayesian framework with trapezium boundaries. multiple models variable prior information to explore impacts different interpretations archaeological record, ultimately favor where appeared between 13,260 12,895 calendar years ago fell out use 11,785 11,390 ago, period 1115 1555 years. When compared analyses Clovis...
Significance Proponents of the altered states consciousness (ASC) model have argued that hallucinogens influenced prehistoric making images in caves and rock shelters. However, lack direct evidence for consumption at any global art site has undermined ASC model. We present first clear ingestion a site, this case, from Pinwheel Cave, California. Quids cave ceiling are shown to be Datura wrightii , Native Californian entheogen, indicating that, rather than illustrating visual phenomena caused...
Institutionalized differences in social status developed on California's northern Channel Islands from the Late Middle (A.D. 650-1150) to 1300-1782) periods. This is associated with proliferation of sedentary communities along coasts these islands and a number important socioeconomic changes, including greater emphasis fishing production non-food craft items. These changes were particularly rapid during Period Transition (MLT; A.D. 1150-1300) partly attributed significant environmental...
Chert outcrops on eastern Santa Cruz Island were of vital importance to the inhabitants Barbara Channel region because their comparatively limited availablity elsewhere California Islands. Temporally diagnostic artifacts and radiocarbon dates from associated shell middens suggest that chert quarries exploited throughout Holocene. The these has been well documented in regard microlith production as part bead industry during late However, relatively little is known about local tool manufacture...
Fresh water availability was an important variable that influenced prehistoric human settlement on California's northern Channel Islands. Previous attempts to understand the islands use watershed size as a proxy for at canyon mouths. In semi‐arid regions, this approach has limitations because streams may lose much or all of their flow groundwater. We developed distributed hydrological model Santa Rosa Island incorporates geospatial and temporal data climate (precipitation, solar radiation,...
The damage and loss of coastal archaeological sites from shoreline transgression other near-coastal processes is common around the world. It negatively impacts our ability to address important research questions including those about colonization New World, which likely occurred along Pacific Coast. Differences in geomorphic context, annual weather patterns, topography, vegetation, bedrock, land-use history lead distinct localized patterns erosion even within small geographic regions. We...
We establish a high-precision radiocarbon chronology for 2 house depressions at CA-SCRI-333, large prehistoric village on the western end of Santa Cruz Island, California, USA. SCRI-333 is mound composed shell midden with more than 50 evident across its surface. develop occupation and activity these (6 32) based stratified sequence accelerator mass spectrometry 14 C dates. Carbonized twig marine ( Mytilus californianus ) samples were selected from well-defined stratigraphic sections....
Shifting from shellfish collecting to fishing as a primary coastal foraging strategy can allow hunter-gatherers obtain more food and settle in larger populations. On California's northern Channel Islands (NCI), after the development of single-piece shell fishhook around 2500 cal BP, diet expanded primarily include nearshore fishes greater numbers. During Medieval Climatic Anomaly (1150–600 BP), settlement on islands condensed small number large villages with high population densities...

ABSTRACTSubmerged shell midden sites and natural deposits can have similar characteristics be difficult to distinguish archaeologically. We excavated two test units from a large (at least 35 m×70 m) submerged mound in Fort Neck Cove southern Rhode Island assess whether it was or cultural origin. This had been recognized as potential archaeological feature early the 1970s. Excavation, radiocarbon dating, subsequent laboratory analysis of materials suggest that oyster reef rather than site. No...
Recent surveys on California's northern Channel Islands have highlighted the ubiquity of small, low-density lithic scatters across coastal terraces and interior ridgelines. These sites typically lack organic materials or diagnostic artifacts are therefore rarely subject archaeological investigation. Here we quantify raw material flake type for nine representative from three distinct parts Santa Rosa Island. The regions located western, eastern, portions island, where Dry Canyon chalcedony,...
