First cosmogenic 10 Be age constraint on the timing of Younger Dryas glaciation and ice cap thickness, western Scottish Highlands
Abstract We use cosmogenic 10 Be surface exposure age techniques at a locality close to Rannoch Moor, western Scottish Highlands, in order to establish the age and chronology of its most recent glaciation. Glacial erratics and an in situ bedrock quartz vein sampled from this site—the summit of Beinn...
