Castlepook in the Cold31801 BCE
Dateline
31,807 BCE is a modern archive reference point within the Late Pleistocene. No Irish event can be fixed securely to this exact year. Evidence from cave deposits, freshwater sediments and glacial geology instead describes a broader cold interval.
Ice-Age Ireland
Open tundra habitats and cold-adapted animals remained present in parts of Ireland while the British-Irish Ice Sheet was expanding. Castlepook Cave in County Cork preserves important mammal remains from this wider period.
Interpretation
The surviving material supports an environmental reconstruction rather than a political narrative. Exact calendar precision is unavailable, so this year is best understood as one point within a changing Ice Age landscape.
Primary Sources
Research draws on National Museum of Ireland collections, Castlepook studies, Derryvree environmental evidence, BRITICE-CHRONO reconstructions and radiocarbon calibration research.
