Uplands Initiative Field Projects 2002-3, Llyn Aled and Gwytherin Survey Area, North Wales. Archaeological Survey Report

An archaeological identification survey of the eastern part of Mynydd Hiraethog North
Wales (centred SH 920590) was undertaken in March 2003. The work was undertaken by
Oxford Archaeology North (OA North) on behalf of the Royal Commission on the Ancient
and Historical Monuments of Wales (RCAHMW) as part of the Uplands Initiative. The
fieldwork consisted of an identification survey to identify, locate and describe
archaeological and historical features within the defined survey area.
The Mynydd Hiraethog study area incorporates Historic Landscape 39 (Countryside
Council for Wales 2003), of which part has been previously surveyed for the Mynydd
Hiraethog Survey by Clywd Powys Archaeological Trust. In addition, the western section
of the Mynydd Hiraethog area has been recorded as part of the present project and is the
subject of a separate report. The present report consists of the results of an extension to the
original survey and is divided into two study areas, comprising c12km² in extent. The
southern most of these areas is to the north of the A453 and is centred on the reservoirs of
Llyn Aled and Aled Isaf. It is an area of open heather moorland encompassing large open
tracts of heather and rough grass moorland which rise steadily to the centre of the area. The
Gwytherin study area was a second, smaller study area, including enclosed land on the
lower slopes rising up from the village of Gwytherin and moorland rising to the south and
east
