Geography

Gorumna Island is linked with the mainland through the Béal an Daingin Bridge. Gorumna properly consists of three individual islands in close proximity, Lettermullen, Teeranea (Irish: Tír an Fhia) and Lettermore.[1]

Geology

Gorumna Island is mostly underlain by intrusive Devonian-aged Galway Granite that formed from crustal melting as a result of the Caledonian Orogeny in the late Silurian. Its southern tip also includes Ordovician-aged bedrock of sedimentary marine rocks and basalt.[2]
