HY 285 140 The programme of geophysical investigations in and around the ‘Heart of Neolithic Orkney’ began in 2002 and to date approximately 240ha have been surveyed including this year’s season (Phases X) which started in May 2007 and is still ongoing. Gradiometry and resistance survey at the Point of Onston around the chambered tomb and within the fortified promontory have revealed a number of anomalies of archaeological interest although the data suggest that few remains exist beyond the visible earthworks. Resistance survey over Big Howe Broch has confirmed the ‘lightbulb’ shaped enclosure ditch suggested by previous gradiometer survey and has detected part of the tower which is approximately 30m in diameter. There is some suggestion of additional stone structures. Elsewhere gradiometer survey has detected numerous responses indicative of ridge and furrow cultivation. Some discrete areas of enhanced response have also been located which may be of archaeological interest.
