Derryvree Between Tills
Archived: 1 October 2026
About 30,395 BCE, Ireland cannot be described through a precise historical year, but Derryvree, County Fermanagh, preserves evidence within a broad calibrated range. Freshwater silts and organic deposits, sealed between glacial tills, show a temporary ice-free wetland during the Late Pleistocene. Plant, insect and small-animal remains indicate treeless, cold, tundra-like mosaics of ponds, mosses, sedges and sparse herbs. Advancing ice was not yet at its maximum, and conditions varied regionally. Southern cave faunas demonstrate glacial animals, although mixed deposits resist exact dating. A possibly cut-marked reindeer bone from Castlepook may indicate fleeting human activity, not settled occupation or social history.
