Introduction
The coastline of North Devon runs transversely across Devonian and Carboniferous strata, but
at Hartland Point it changes direction abruptly towards the east (see Figure
3.1 for general
location). Much of the coastline is cliffed, broken only by small valleys that have been eroded to
present sea level (for example at Crackington Haven) or form hanging valleys (for example
south of Hartland Quay). South of Hartland Point, the relationships between coastal valley
systems and coastal retreat are of particular interest. This site contains fine examples of cliffs
and shore platforms, and demonstrates clear relationships between cliff forms, platform
development and lithological variations (Arber, 1911). Furthermore, it is also noted for a
remarkable set of river valleys that have been truncated by the cliffline, so that their floors
now lie well above present sea-level (Arber, 1911; Arber, 1949). Unlike similarly truncated
streams in the south-west Isle of Wight (see GCR site report in Chapter 4), those in the
Hartland Quay area have been unable to erode valleys to sea level and so many reach the
shore via waterfalls (Arber, 1911). In some cases the streams have also cut gorges that
include waterfalls. In common with other hard-rock coasts, Hartland Quay has been the
attention of only limited research since the detailed monograph by
Arber (1911). Keene (1986,
1996) and Goudie and Gardner (1985) have reviewed the development of the site in the light
of more recent interpretations of Pleistocene geology in western Britain (
