A snapshot of Uplands Initiative work at Manod Bach, Gwynedd

Royal Commission staff members, Jon Dollery and Nikki Vousden, recently joined the Commission’s Uplands project co-ordinator, David Leighton, on a visit to Manod Bach, near Blaenau Ffestiniog. We shadowed archaeologists, Richard Hayman and Wendy Horton, who were undertaking a survey of the area as part of the Royal Commission led Uplands Initiative. The long-running project aims to survey and record archaeology on all moorland over 244m above sea level. Some 2380 square km has been surveyed to date. Each year the Royal Commission awards grants to enable teams of archaeologists to record monuments and features in some 150 square km of landscape. Before work on the ground proceeds an archaeologist within the Royal Commission examines all vertical aerial photographs held at the Commission and uses GIS software to produce maps of all archaeological features. This work is currently undertaken by Mapping Officer, Jon Dollery. The mapping guides archaeologists in the identification of features as they walk in parallel 30-50m transects across the landscape. It also helps them understand long linear features such as trackways, artificial watercourses or former field boundaries.

Conversely, archaeologists on the ground can identify small features such as stone-built cairns or prehistoric standing stones that may be too small for identification from the air.

Our field-walking resulted in the verification of numerous mapped features, including a sheep fold and an intricately built sheep wash utilising natural landscape features. It also resulted in the identification of features not visible on aerial photographs, including two mine shafts, one of which was previously unrecorded.

The fieldwork was a valuable opportunity to see how our desk-based work on air photograph interpretation aids the identification of features on the ground.
