Derryvree’s Buried Tundra Pool
Archived: 21 September 2026
Abstract
Around 30,972 BCE, Ireland’s history is reconstructed from environmental evidence rather than recorded events. At Derryvree, County Fermanagh, freshwater sediments between glacial tills show an ice-free cold wetland, with pools, sedges, mosses, insects and open tundra vegetation, later buried by renewed ice. Radiocarbon dating places this horizon broadly within the period, not in a precise year. Castlepook Cave, County Cork, preserves mixed remains of mammoth, reindeer, giant deer, bears, hyaenas and other cold-stage fauna, demonstrating varied habitats over millennia. A possibly cut-marked reindeer bone may indicate brief human presence, but no settlement evidence exists. Later ice destroyed this fragile record.
