Tievebulliagh is a 402m high mountain in the Glens of Antrim Northern Ireland. It forms the watershed between Glenann to the north and Glenballyeamon to the south.

[edit] Geology

Tievebulliagh is formed from a volcanic plug, the intense heat generated by molten basalt has given rise to the formation of a durable flint, porcellanite, which is found at the foot of the eastern scree slope of the mountain.^[1]

[edit] Archaeology

Evidence has been discovered of a Neolithic axe quarry at the foot of Tievebulliagh.^[2] Flint axe heads fashioned from porcellanite that originate from this quarry have been found across the British Isles, from Outer Hebrides to the south coast of England and across the rest of Ireland.^[3] There is a Bronze Age cairn on the mountain top.
