Before Maximum Ice
Archived: 9 September 2026
Around 31,950 BCE, Ireland lay within the Midlandian cold stage of the Late Pleistocene, before the Last Glacial Maximum. Its treeless, periglacial landscapes comprised tundra, grasses, sedges, dwarf shrubs, unstable rivers and frost-shattered ground, while lowered seas altered coastlines without necessarily providing easy land routes. Cave deposits, especially Castlepook in Cork, preserve evidence of mammoth, reindeer, giant deer, predators and Arctic-adapted mammals, though accumulated remains cannot reconstruct one ecosystem. A possibly cut-marked reindeer bone, dated near 33,000 years ago, may indicate human butchery. Yet no settlement, tools, hearths or continuous occupation are established. It represents environmental change and tentative presence.
