Sahlin, E.A.U. and Glasser, N.F. (2008) Geomorphological map of Cadair Idris, Wales, Journal of Maps, v2008, 299-314.

This is a new 1:10 000 scale geomorphological map of Cadair Idris in Wales, produced by interpretating aerial photographs and field investigations of landform/sediment associations. Digital Elevation Models (sourced from NEXTMap Britain) were used to supplement the mapping, enhancing the ability to observe and identify landforms, bedrock structure and landscape composition.

The resulting map shows the distribution of glacial, periglacial and postglacial landforms such as cirques, end moraines, glacial striations, tors, meltwater channels, scree slopes and alluvial fans. Some of these features have not previously been identified. The geomorphological mapping will also be used as basis for geoconservation planning by the Countryside Council for Wales and the Welsh Regionally Important Geological /Geomorphological Sites groups.
