Maguirebridge Between Tills
Archived: 20 September 2026
Around 31,032 BCE, Ireland’s history is environmental rather than documentary. Derryvree, near Maguiresbridge, preserves freshwater silts between glacial tills, indicating a temporarily ice-free, treeless wetland during a broadly dated MIS 3 interval. Mosses, sedges, aquatic plants and insects occupied shallow pools amid severe, variable cold. Comparable deposits confirm shifting conditions between glacial advances. Ireland’s ice extent, coastlines and access routes remained uncertain as the British–Irish Ice Sheet fluctuated and sea levels fell. Cave faunas included reindeer, mammoth, deer, bear and hyaena, but were accumulated over different episodes. No secure evidence establishes human settlement, society, trade or political organisation at all.
