Rapid Communication Support for the Innuitian Ice Sheet in the Canadian High Arctic during the Last Glacial Maximum
ABSTRACT: The extent of glacier ice in the Canadian High Arctic during the Last Glacial Maximum (LGM) has been debated for decades. One school proposed a regional Innuitian Ice Sheet whereas another proposed a smaller, non-contiguous Franklin Ice Complex. Research throughout western Nares Strait sup...
