Ice caps existed throughout the Lateglacial Interstadial in northern Scotland
Abstract We constrain, in detail, fluctuations of two former ice caps in NW Scotland with multibeam seabed surveys, geomorphological mapping and cosmogenic 10 Be isotope analyses. We map a continuous sequence of 40 recessional moraines stretching from ∼10 km offshore to the Wester Ross mountains. Su...
