Camlough Mountain (Sliabh gCuircín)
The rock that makes up Camlough Mountain is called granodiorite. Granodiorite, just like the rocks that make up Slieve Gullion, forms from the cooling, deep underground, of molten magma. However, unlike the rocks that make up Slieve Gullion and the Ring of Gullion, which were formed around 60 million years ago, the granodiorites of Camlough Mountain are around 400 million years old. Whereas the younger rocks of Gullion are associated with igneous activity related to the formation of the present day Atlantic Ocean, the rocks of Camlough Mountain are associated with igneous activity related to the closure of a precursor to the present day Atlantic, the now long disappeared Lapetus Ocean.
Camlough (from Irish: Camloch, meaning “crooked lake”) is a small village five kilometres west of Newry in County Armagh, Northern Ireland. The village is named after a lake, known as Cam Lough, in the parish, which is about 90 acres in extent. South of the village is Camlough Mountain (Slieve Girkin, Sliabh gCuircín) which is part of the Ring of Gullion. The Ring of Gullion (Irish: Fáinne Cnoc Shliabh gCuillinn, meaning “hill ring of Slieve Gullion“) is a geological formation and area and is officially designated as an Area of Outstanding Natural Beauty, (AONB).
