Fermanagh’s Unburied Waters
Archived: 4 October 2026
Abstract
Labelled 30,275 BCE, this interval cannot be tied to a specific Irish event or year. Derryvree, County Fermanagh, preserves freshwater organic deposits between glacial tills, indicating a locally ice-free or ice-margin phase within MIS 3, broadly dated to 34,950–29,750 BCE. Its plants and animals reveal cold, open tundra wetland, not permanent ice cover. Castlepook Cave, County Cork, documents fauna including reindeer, mammoth and giant deer, but not a single contemporaneous community. A butchered reindeer bone suggests human visits, yet no evidence demonstrates settlement. The record instead reveals dynamic, biologically active Ireland, while requiring caution over climate, geography and human activity.
