Excavations of the Allasdale Dunes on the island of Barra, in the Western Isles of Scotland, were undertaken by Wessex Archaeology and funded by Videotext Communications Ltd., in May of 2007. The site, which include findings from the Neolithic, Bronze Age, and Iron Age periods, was unearthed after a storm blew away the sand dunes and revealed the site. Barra has a vast archaeological history, and the excavation of this site yielded great findings, including pottery, worked stone, human remains and more.
According to the site report provided by Wessex Archaeology, several methods of geophysical survey were undertaken by GSB Prospection prior to excavation. GSB used both resistance and magnetic survey to assess the site. The agency also used ground penetrating radar (GPR) to access the subsurface of the site. GSB surveyed three separate areas in the Allasdale Dunes. Henry Chapman, of the University of Birmingham, set out the survey grid for the excavations, which was tied into the Ordnance Survey grid, a mapping agency of the government of Great Britain, using global positioning system (GPS). In his own report on the site on Barra, in which he analyzes the archaeological value of paraeosols (layers of soil from a previous age preserved deep within the earth) on the site, Chapman states that GPR survey, topographic modelling, and a borehole excavation were using in his analysis of the site (Chapman, Adcock, Gater 2009). A deflation hollow, where blown sand creates a depression in the ground, was separated into three separate areas for archaeological survey, which were excavated by hand and with the use of metal detectors. A fourth area, located 100 meters north-east of the area labelled “Area 2”, was investigated after previous arc...
