Early maximum extent of paleoglaciers from Mediterranean mountains during the last glaciation
Mountain glaciers respond directly to changes in precipitation and temperature, thus their margin extent is a high-sensitivity climate proxy. Here, we present a robust Be-10 chronology for the glacier maximum areal extent of central Spain paleoglaciers dated at 26.1 +/- 1.3 ka BP. These glaciers rea...
