Crag Cave’s Broken Stalagmites
Archived: 20 September 2026
Around 31,042 BCE, Ireland lay within a fluctuating late Ice Age environment rather than a fixed ice sheet. Derryvree sediments in Fermanagh record treeless, waterlogged tundra wetlands between glacial advances, while Crag Cave stalagmites in Kerry indicate episodically milder conditions allowing calcite growth. Castlepook Cave, Cork, preserves diverse cold-stage fauna, including reindeer, mammoth, hyaena and lemmings, though cave deposits mix material from different times. A marked reindeer femur may indicate human butchery about 33,000 years ago, but cannot prove settlement. Later ice, sea-level change and early excavations obscured much evidence, leaving environmental possibility rather than documented society. Certainty remains limited.
