NWHG Ref. 040 — Sgonnan Mor, Dubh Loch Beag, Upper Glen Oykel
Location, grid reference and photograph
The site comprises three separate areas located within upper Glen Oykel, Grid Ref. NC 295145 —
GCR site reference, block, volume and notified feature of SSSI?
GCR Ref. 1160, Moine Block, Vol. 34. Notified feature of Ben More Assynt SSSI.
Description and geological significance
The three separate areas contain exposures of the Ben More Thrust and its associated structures. The site areas are considered representative of the Ben More Thrust and associated fold and thrust structures in the Assynt Culmination. They are also representative of the relationships between Lewisian and Torridonian units in the Ben More Thrust Sheet.
Accessibility
The site areas lie within a very remote and mountainous area, many kms from the nearest road, requiring a long walk over undulating and challenging terrain. There is therefore no all abilities access.
Conservation
Low conservation requirement due to the nature, scale and location of the site areas.
Visibility and “clarity”
The main features are visible to the specialist eye once this very remote area is reached.
Interpretation and interpretation potential
The very remote and difficult nature of the site areas and the specialised aspect of their geological significance rule out any meaningful interpretation potential for the general public. The areas could be developed as an educational resource and included in a future Geopark guide.
