Hubbard Glacier, Alaska: Growing and Advancing in Spite of Global Climate Change and the 1986 and 2002 Russell Lake Outburst Floods
Trabant DC, March RS, Thomas DS. 2003. Hubbard Glacier, Alaska: Growing and Advancing in Spite of Global Climate Change and the 1986 and 2002 Russell Lake Outburst Floods. U.S. Geological Survey (USGS) Fact Sheet. 001-03. U.S. Geological Survey (USGS)
Hubbard Glacier, the largest calving glacier on the North American Continent (25 percent larger than Rhode Island), advanced across the entrance to 35-mile-long Russell Fiord (fi g.1) during June 2002, temporarily turning it into a lake. Hubbard Glacier has been advancing for more than 100 years and has twice closed the entrance to Russell Fiord during the last 16 years by squeezing and pushing submarine glacial sediments across the mouth of the fi ord (fi gs. 2 and 3). Water fl owing into the cutoff fi ord from mountain streams and glacier melt causes the level of Russell Lake to rise. However both the 1986 and 2002 dams failed (fi g. 4) before the lake altitude rose enough for water to spill over a low pass at the far end of the fi ord and enter the Situk River drainage, a worldclass sport and commercial fi shery near Yakutat, Alaska.
