Toward a Cultural Landscape Atlas: Representing all the Landscape as Cultural

Many government and non‐statutory registers utilise point datasets to represent cultural heritage places. An effect of this approach is to emphasise that cultural heritage comprises a series of spatially discrete material remains or ‘sites’, suggesting discrete locations which are somehow disconnected from their broader historical and landscape contexts. We advocate an alternative in which spatial representation of heritage is set within a cultural landscape framework, acknowledging that all parts of the landscape have inter‐connected cultural histories, associations and meanings resulting from long‐term and ongoing human–environmental interactions. Results from a collaborative cultural heritage research project undertaken at Culgoa National Park in Australia demonstrate the advantage of this approach. The mapping products produced by the work comprise an interactive electronic DVD Atlas and hard copy maps. Both focus on meeting the management needs of field‐based park staff.     

Where is the Caribbean? French Colonial Archaeology in the English Lake

Archaeological investigation of the Caribbean region has generally incorporated unquestioned assumptions about the nature and scale of the context. Most work has been done in the Anglophone Caribbean, and has implicitly taken the English colonial world as the normative context for comparative analysis. This view leaves out a significant portion of the Caribbean colonial world—that of the French imperial program. The French colonial venture in the Caribbean has, until recently, been overlooked by historical archaeology. Recent survey and excavation of sugar, indigo and coffee plantation sites, as well as urban archaeological work, has begun to shed light upon the nature of French colonial life as distinct from that in the Anglophone Caribbean, and also on the ways that the experiences on specific French islands were different from each other. The individual histories of Martinique and Guadeloupe are contrasted in this paper, with reference to the nature of the archaeological record that has been explored, and that remains to be investigated.     

Correcting temporal frequency distributions for taphonomic bias

In this paper, we expand upon a prior study [Surovell, T.A., Brantingham, P.J., 2007. A note on the use of temporal frequency distributions in studies of prehistoric demography. Journal of Archaeological Science 34, 1868–1877.] that explored the problem of taphonomic bias. Taphonomic bias refers to the tendency for younger things to be over-represented relative to older things in the archaeological record due to the operation of destructive processes like erosion and weathering. Using a database of radiocarbon dated volcanic deposits from Bryson, R.U., Bryson, R.A., Ruter, A. [2006. A calibrated radiocarbon database of late Quaternary volcanic eruptions. Earth Discussions 1, 123–124.], we develop an empirical model of taphonomic bias. In contrast to our prior study in which we modeled taphonomic bias as an exponential function wherein the likelihood of site loss remains constant through time, we argue that the probability of site destruction actually decreases with site age. We further demonstrate how this model can be used to correct temporal frequency distributions and extract demographic histories. We illustrate this approach using databases of radiocarbon dates from rockshelter and open-air sites in the Bighorn Basin, Wyoming, USA, and mammoths and humans in Siberia, Russia.     

The devolution of mudbrick: ethnoarchaeology of abandoned earthen dwellings in the Bolivian Andes

This ethno-geoarchaeological study considers the formation of archaeological deposits through a study of abandoned contemporary mudbrick structures on the Taraco Peninsula, Bolivia. The study site was a domestic compound with rooms for different functions that had been abandoned for over 50 years. Structures were in variable states of decay in terms of roof cover, walling integrity and abandonment fills. Geoarchaeological samples were collected from intact and weathered adobes, earthen hearths, mud plaster, and flooring. Adobes and mud plaster were locally derived from topsoil containing archaeological sediments with added gravel and plant temper. This study found a relatively light anthropogenic signature for decayed earthen houses.Rising damp exfoliated mud plaster despite un-mortared cobble wall foundations. Organic matter from roof fall attracted thriving soil faunal populations, which furthered site destruction through bioturbation, particularly packed earth floors. Sediments derived from weathered mudbrick retained little evidence of prior use as construction materials unless exposed to heat. Sediments exposed to high-temperatures produced the most distinctive rubified features but were structurally compromised. Isolated thermal features from decomposed adobe would not be distinguishable from other hearth types. Adobes exposed to low or moderate heat had few distinctive features in thin section. Intact adobes and floors that were not exposed to heat have fewer pores than natural sediments and distinctive grass inclusions. These adobes disarticulated into loose sediments when exposed to weathering. Adobe fall outside the crumbling structures blended into topsoil.This study sheds light on functional attributes of pre-Columbian construction practices. Thick, fine-textured sterile flooring is commonly encountered in the study region. This would control bioturbation from roof fall in a previous occupation enabling reconstruction in abandoned dwellings. In contrast to the contemporary dwelling, prehistoric mortared cobble foundations would resist rising damp. Cobbles without mortar may relate more to design and construction than durability. These contrasts between contemporary and prehistory construction practices reflect differences in the design, construction costs and functional use-life of adobe structures.
