Strabane Glen ASSI

Strabane Glen is a narrow valley supporting a calcareous ash/hazel woodland which is atypical of this region and whose presence is related to the underlying geology.

The valley represents a line of weakness between the Upper Dalradian schists and a basic igneous unit, possibly enhanced by local faulting. It was developed as a meltwater channel during the final deglaciation of the Sperrins ice, as indicated by outwash deposits and by washed rock outcrops on the valley sides.
