“…The data from CA-SMI-87 corroborate the findings of previous studies by Brown (1985), Cameron et al (1990), Leach et al (1998), Wandsnider (1988, and others, demonstrating that eolian disturbances are integrally linked to vegetation and ground cover, with those areas that are generally well covered exhibiting the best preservation. The data from CA-SMI-87, however, indicate that archaeologists cannot assume that because site deposits, including stratified shell middens exhibiting vertical variation, are presently covered with vegetation or sediment that those deposits have always been sealed.…”

“…Working in west Texas and southern New Mexico, Leach et al (1998) also documented the role of wind in structuring the size, content, and formation of lithic scatters in the area. In Australia, Cameron et al (1990) noted the eolian destruction of in situ deposits, as well as the creation of new secondary sites by eolian deposition. Based on experiments conducted in South African dune fields, lithics, particularly small ones, moved relatively rapidly because of deflation (Lancaster, 1986).…”

“…Perhaps the most widespread impact of wind is deflation, the removal of light objects by high winds, resulting in a lag deposit of heavy constituents or a palimpsest of materials from different time periods (Schiffer, 1987;Waters, 1992;Dincauze, 2000). Numerous studies have focused on the role of wind in the formation and preservation of archaeological deposits (Lancaster, 1986;Wandsnider, 1988;Cameron et al, 1990;Curry, 1992;Camuffo, 1993;Leach et al, 1998;Ernst, 2000), but relatively few have examined the effects of wind on coastal archaeological sites (see Brown, 1984Brown, , 1985 for a notable exception). Coastal regions tend to have strong winds with considerably higher velocities than nearby interior regions (Livingstone and Warren, 1996:6).…”

Geomorphological evidence and historical wind records indicate that eolian processes have heavily influenced San Miguel Island environments for much of the Late Quaternary. The island is almost constantly bombarded by prevailing northwesterly winds, with peak velocities exceeding 75 km/h and wind gusts reaching over 100 km/h. These strong winds played an important role in the location, formation, and preservation of the island's more than 600 archaeological sites. Excavation and surface collection at a stratified Middle and Late Holocene archaeological site on the island's north coast suggest that wind related disturbances result in significant displacement of light fish bones, produce concentrations of shellfish and heavy mammal bones, and cause significant abrasion, etching, and polishing of bones, shells, and artifacts. These data illustrate that wind not only alters surface materials but can significantly disturb subsurface deposits to a depth of at least 20 cm. Working in concert with a variety of taphonomic processes, wind can play a fundamental role in the preservation of archaeological sites and careful scrutiny during excavation and laboratory analysis is required to delineate its effects.

“…Entre los atributos de estas concentraciones, se observa una reducida variabilidad de tamaños y una densidad superior a la observada en sus alrededores (7 artefactos/m 2 vs 0,55 artefactos/m 2 , respectivamente). Entonces, en las planicies eololacustres la presencia de artefactos de tamaños pequeños no puede ser considerada un proxy de la integridad del conjunto como sí puede serlo en espacios afectados fundamentalmente por la acción eólica (aunque ver Cameron et al 1990). Aquí el efecto más importante del viento es la generación del oleaje y el "arrinconamiento" del agua de la laguna sobre las márgenes orientales.…”

ResumenEl objetivo de esta investigación es evaluar el impacto de la dinámica geomorfológica local sobre los patrones espaciales y la integridad de los conjuntos líticos recuperados en las planicies eololacustres ubicadas en el norte de la bahía San Sebastián (Tierra del Fuego, Argentina). La información geológica y los datos experimentales obtenidos en estudios longitudinales realizados en el sector son utilizados para delinear un modelo de la dinámica ambiental. Luego, se generan expectativas para el registro arqueológico recuperado en las planicies. Finalmente, los patrones de los conjuntos líticos de una localidad arqueológica son evaluados a la luz del modelo propuesto y se exponen las tendencias generales para el registro lítico local. Se concluye que la ocurrencia, características y patrones de distribución de los artefactos líticos están fuertemente influidos por los procesos tafonómicos que actúan sobre ellos.

AbstractThis paper aims to assess the implications of local geomorphic dynamic for spatial patterns and the archaeological integrity of lithic assemblages deposited within the aeolian-lacustrine plains of northern San Sebastian Bay (Tierra del Fuego, Argentina). Geological and experimental data resulted from longitudinal studies is used to outline a model of the local environmental dynamic. Then, expectations for aeolian-lacustrine plains lithic record are derived. Finally, the model is applied to the distributional study of archaeological assemblages from one locality and the general trends of the local lithic record are highlighted. This research concludes that taphonomic processes strongly influence lithic artifacts occurrence, characteristics, as well as their distribution.

“…These aeolian sand dunes contain the archaeological material product of human occupations that took place in a dune setting or ancient marine terraces which are covered by aeolian sediments (Mayer 2002). Due to wind erosion, and the deflation processes it causes, the archaeological record was alternatively buried and exposed (Cameron et al 1990;Fanning & Holdaway 2001;Favier Dubois et al 2008). Previous work in the area indicated the presence of a blowout dune, a collapsed dune profile and surface scatters (Gómez Otero 2006).…”

This paper focuses on surface lithic artefacts from Holocene coastal hunter gatherer occupations of Arroyo Verde archaeological locality (Rio Negro province, Northern Patagonia, Argentina). The study of lithic assemblages collected at a deflation surface surrounded by stabilised sand dunes near the coastline, shows that wind produce significant corrasion (wind abrasion) of artefacts and affects preservation of small and medium size artefacts. The sample is mainly composed of chert knapping debitage with abraded and polished edges and surfaces. The artefact size distribution suggests that a subset of the assemblage exhibits good preservation, possibly due to the recent subaerial exposure. Furthermore, carbonate and mould coatings were recorded over the artefacts surface in contact with the ground, which indicates the presence of humid conditions in the sand dunes deflation area. In order to explore the factors that affected assemblage stability conditions in the locus, a machine learning based decision tree was applied. The model predicts and defines a threshold at which the occurrence of instability conditions may appear. Also, it suggests that relative altitude of artefacts within the deflation hollow is the primary variable explaining the exposure conditions recorded in the artefacts and it points out processes of differential deflation over time. The data presented here illustrates how wind alters local surface materials and emphasizes that a taphonomic perspective is needed to assess the formation processes within northern Patagonia coastal archaeological assemblages.
