Flood-Damaged Canals and Human Response,A.D. 1000–1400, Phoenix,Arizona, USA

The scale of prehistoric canal construction in the North American Southwest peaked in a.d. 450–1450, during what has been named the Hohokam Millennium. Explanations for the eventual Hohokam “collapse” remain elusive. Environmental disturbances, such as floods, that were once manageable may have become unmanageable. Recent archaeological excavations of Hohokam canals in Phoenix identified stratigraphic evidence for three destructive floods that date to a.d. 1000–1400 within two large main canals in System 2, Hagenstad and Woodbury’s North. Woodbury’s North Canal was flood-damaged and abandoned sometime after a.d. 1300. Thereafter, no main canals of similar size were constructed to supply villages within System 2 and the area was depopulated. Our investigation provides the first stratigraphic evidence for a destructive flood during the late Classic period in the lower Salt River Valley and is compatible with the hypothesis of diminished resilience to environmental disturbance at the end of the Hohokam Millennium.     

The Classic-period pictographs at Juliq’ Cave,Alta Verapaz,Guatemala: an interdisciplinary approach to cave art as organizing principle

The Cave of Juliq’ in Alta Verapaz, Guatemala contains an impressive corpus of ancient Maya rock art. Unlike other examples of rock art in this area, the Juliq’ pictographs are simply rendered, generally consisting of lines, handprints, and other basic shapes. We thus focus on context rather than on iconographic content in order to access the meaning of these ancient pictographs. We argue that they were used to record human presence in and movement through the alien cave environment in specific ways, demarcating procession routes, points of transition, moments of physical prowess, and places charged with sacred power. These circuits within Juliq’ reflect attempts to order the Underworld landscape and link it to the surface world through ritual movement akin to aboveground ritual processions.     

Using Sector‐Scan Sonar for the Survey and Management of Submerged Archaeological Sites

This article reports the results of using a sector‐scan sonar to record diverse submerged archaeological sites in shallow and deep water. The Kongsberg MS1000 sector‐scan sonar was developed for commercial applications, typically underwater inspections of bridges, dams, ports and harbours. The ability of the device to rapidly generate high‐quality, geometrically accurate scans of submerged features, coupled with its ease of use and deployment make it a potentially important, yet largely overlooked, tool for survey and management of underwater archaeological sites. As one of several technologies available, the paper examines its advantages and limitations, and considers, through case studies, under which conditions it is most effectively deployed.     

Underwater Excavation at Ederline Crannog, Loch Awe, Argyll, Scotland

A trial excavation was carried out on the near-submerged crannog at Ederline Boathouse, Loch Awe, in July 2004. A trench measuring 3 × 5 m was opened on the northern side, in c .3 m of water. Around 1 m of organic deposits was encountered, along with structural timbers and animal bones. Despite a previous 4th century BC radiocarbon determination from a structural timber, a sherd of E ware from a sealed context gives an Early Historic date for the deposits excavated in 2004. The results from this first intrusive investigation of a Loch Awe crannog demonstrate that these sites are complex and long-lived.

Chemical and strontium isotope analysis of Yaozhou celadon glaze

To produce useful information about the raw materials used in northern Chinese Yaozhou celadon glazes Chinese glazes (especially the source of the calcium‐bearing flux), Sr isotope analysis has been used for the first time. Yaozhou celadon is one of the most important representatives of northern Chinese greenware. The study has enhanced our understanding of the raw material sources used to make Yaozhou glazes dating from the Tang to Northern Song dynasties. It is highly likely that ‘Fuping stone’ mentioned in the historical record is not the main raw material used to make Yaozhou celadon glazes of the Tang to Northern Song dynasties. The results of ⁸⁷Sr/⁸⁶Sr analysis of the Yaozhou celadon glazes studied produce relatively consistent ⁸⁷Sr/⁸⁶Sr isotopic signatures, with a wide variation of relatively high Sr concentrations. This is firm evidence that a calcium‐bearing plant ash was the source of the calcium and of the flux in the Celedon glazes studied, and not, as some have suggested, limestone or ‘Liaojiang stone’. The study had illustrated that the present approach has great potential in providing a new way of reconstructing porcelain glaze technology.     

Calcium isotopes in archaeological bones and their relationship to dairy consumption

The calcium isotope ratios (δ^44/42Ca) of bones from humans and fauna from three archaeological sites, Taforalt, Abu Hureyra, and Danebury, are evaluated in order to assess whether calcium isotope ratios of bones can be used to detect dairy consumption by adult humans. At each site the fauna δ^44/42Ca is the same regardless of species, while the humans have lower δ^44/42Ca than the local animals by 0.24–0.41‰ (site means). However we cannot ascribe this difference to dairy consumption, given this human–faunal difference also occurs in Epipalaeolithic and Mesolithic adult humans, where dairy consumption is unlikely. Rather, this difference appears to be a result of differences in metabolic processes or other aspects of diet between humans and fauna. Minimal isotopic change in sequential acid leaches of bone powders and consideration of the high calcium concentration in bone suggest that bone calcium isotope ratios are not substantially affected by diagenetic change.     

The Hyde Park Rally of 9 March 1890: a British response to Russian atrocities

In December 1889 The Times carried a report detailing the killing of a group of Russian political exiles in Yakutsk, Siberia. Public outrage at this atrocity was compounded two months later with news of the flogging and suicide of female political prisoners in another Siberian penal colony. These events sparked a series of international protests, and the British reaction culminated in a march and rally in Hyde Park. This article examines the causes and timing of this outburst of militancy and draws attention to the wide range of organisations and individuals who were responsible for the growth of support within Britain for the cause of the Russian ant-tsarist opposition. Drawing on Russian and British archival documents and contemporary press reports, it throws fresh light on the Siberian events themselves as well as on the convergence in London of a range of disparate political groupings determined to show a unified front in support of their Russian brethren.
