Recent flights over the Lowell Glacier inside Kluane National Park & Reserve reveal that the glacier appears to be surging. Based on observations made by a local pilot in autumn of 2009, February 2010 and again in March 2010, the glacier appears to have surged approximately 400m over the winter. This video of the toe area of the glacier was filmed on March 22, 2010. If you look carefully, you can see how the glacier has pushed into and is cracking the ice of Lowell Lake, which is an enlargement of the Alsek River at the base of the glacier. The Lowell Glacier is also known as "Naluday" (pronounced Naa-kloo-dei) in Southern Tutchone. Naluday translates to "fish stop," a reference to the fact that in the geological past, the glacier has surged far enough to completely block off the Alsek River and interrupt migrations of historical salmon populations.
