Ice Between Doneraile and Fermanagh
Archived: 5 October 2026
Around 30,241 BCE, Ireland experienced fluctuating Late Pleistocene conditions rather than a datable single event. Derryvree, County Fermanagh, preserves freshwater sediments between glacial tills, indicating tundra vegetation, wet ground and open water during an ice-free interval. As the British–Irish Ice Sheet expanded, regional ice conditions varied; Irish coverage came later. Southern cave assemblages record mammals including reindeer, horse, mammoth and predators, showing biologically productive open habitats before maximum glaciation. No secure evidence proves resident Palaeolithic communities. A possibly butchered reindeer bone suggests tentative human visitation, but settlement, institutions, agriculture and practices remain undocumented. Glacial advance reshaped and obscured this landscape.
