Derryvree’s Buried Catchment
Archived: 28 September 2026
At 30,520 BCE, Ireland lay within the Late Pleistocene Midlandian cold stage, not a datable historical year. Derryvree in County Fermanagh preserves freshwater sediments between tills, showing an ice-free interval before renewed glaciation. Radiocarbon evidence places these deposits broadly between 34,950 and 29,750 BCE. Fossils indicate open, treeless tundra, seasonal water, wetland plants and severe periglacial conditions. Cave faunas attest that reindeer, mammoth and carnivores occurred in Ireland at varying times. A cut-marked reindeer bone from Castlepook suggests possible human activity, but no secure settlement evidence exists. The article therefore depicts changing environments, rather than permanent occupation or historical events.
