A lynchet forms the eastern extent of a settlement and agricultural landscape at Craig Cerrig-gleisiad (NPRN 84784). Visible only in low bracken conditions it forms a persistent linear feature over a distance of about 375m (aligned N-S) where it follows the 440m contour (between SN96602234 and SN96672267), crossing it at its southern extent. In places the scarp rises to 0.6m high with a maximum width of 1.5m.
