Courtmacsherry’s Raised Shore
Archived: 28 September 2026
Around 30,523 BCE, Ireland was an unstable Late Pleistocene landscape rather than a historical society. Greenland records suggest abrupt climatic shifts, while Ireland experienced cold, open, periglacial conditions, with fluctuating ice, sea levels and wetlands. Courtmacsherry’s raised shore indicates complex coastal change and possible early growth of British–Irish ice, although precise ice limits remain uncertain. Derryvree preserves a freshwater, tundra-like interval later buried beneath till. Castlepook Cave bones show diverse cold-stage fauna, but not simultaneous species or settlement. Possible human activity remains unproven: no secure contemporary hearths, tools or population evidence exist. These archives document environmental change, not calendar-precise events.
