Evidence for an ice‐free Wrangel Island, northeast Siberia during the Last Glacial Maximum
10 Be and 26 Al surface exposure ages from 22 tors and bedrock samples from Wrangel Island, northeast Siberia, indicate that the East Siberian and Chukchi shelves were ice‐free during the Last Glacial Maximum (LGM). The paucity of glacial landforms and deposits, the absence of erratics and the prese...
