=== Locality 9.1 Allt Leacach [NH 177 768] ===

Allt Leacach [[Media:EGS_MOI_Fig_09_01.jpg|(Fig. 9.1)]]. Start of the Sgurr Beag Thrust traverse (900-800m structurally below the Sgurr Beag Thrust).

The Inverbroom Psammite exposed in the waterfalls above and below the bridge, consists of banded psammites and semi-pelites with a flat-lying D<sub>2</sub> planar fabric crenulated by D<sub>3</sub>. Occasional minor D<sub>3 </sub>folds are exposed in the stream below the bridge. Note particularly the undulating style of the bedding planes with rare cross-bedding, the angular discordance between early quartz veins and the foliation/bedding plane, and the intensity of the stretching lineation in the psammites.

About 1.5km further down the road towards Dundonnell, an untarred track leads from the road to the SW [NH 162 761]. Parking for five cars is available in a lay-by, 100m further along the road.
