The Foinaven site occupies a vast mountainous area extending for over 15 km from the head of Loch Eriboll to Loch Stack, Grid Ref.
GCR Ref. N/A, Moine Block, Vol. 34. Notification proposed for Foinaven SSSI.
The Foinaven site contains some of the most continuous exposure of thrusts in the British Isles and includes the type example of duplex structure. It contains exceptional examples of thrust structures in the Moine Thrust Belt, including classic examples of duplexes involving Cambrian quartzites and subsidiary dolomitic shales (Fucoid Beds). Near three-dimensional exposures of thrust geometry are some of the best to be found in Europe.
Access is very limited due to the remote and mountainous nature of this area, requiring a very long walk over difficult and arduous terrain by suitably equipped and experienced people. No all abilities access.
Low conservation requirement due to scale and location of site area.
The visibility is excellent and the key features are very clear to geological specialists, once the respective locations have been accessed The visual impact is high and the site area is truly dramatic and inspiring to both specialists and the lay-public.
The site area is commonly used by geology students and researchers to illustrate the range and complexity of structural geometries which can result from repeated imbrications and ramp-flat thrust surfaces in addition to providing excellent sections across parts of the Moine Thrust Belt. There are no interpretation panels, and such a panel would, due to the scale and remote location of the site area, not be appropriate. Nonetheless, such an important area should certainly be included in a future Geopark guide and may merit the development of a guided walk for the general public as well as for specialists. Considerable potential as an educational resource.
