Derryvree’s Juniper Waters
Archived: 22 September 2026
About 30,864 BCE, Ireland lay within Marine Isotope Stage 3, not a date associated with identifiable events or communities. Derryvree, County Fermanagh, preserves freshwater sediments deposited between ice advances, calibrated broadly to encompass this year. Plant and faunal remains indicate a cold, open, periglacial landscape of wet hollows, sedges, mosses, juniper and sparse vegetation. Climatic conditions shifted abruptly, while ice distribution remained regionally variable. Cave finds demonstrate Ice-Age mammals, including reindeer, mammoth and hyaena, occupied viable habitats. A possibly tool-marked Castlepook reindeer bone suggests, but cannot prove, human presence. No secure evidence establishes settlement, society or sustained occupation in Ireland.
