Hubbard Glacier refuses to fade away
By Ned Rozell

18 Jul 09 - A few weeks ago I ran an article about Alaska's Hubbard Glacier advancing 7 feet per day. Here's a lot more information about Hubbard Glacier, including a link where you can track its progress.

Hubbard Glacier north of Yakutat crept to within 100 yards of Gilbert Point in June 2007.  George Kalli of the U.S. Army Corps of Engineers took this photo in May 2007.

16 Jan 08 – “As you read this, a rogue glacier is again threatening a small town.

“Hubbard Glacier dips its tongue into salt water about 40 miles north of Yakutat, Alaska, home to about 600 people. Fed by fields of ice so immense that the glacier will rumble forward regardless of how warm the planet gets in the near future, Hubbard Glacier made headlines in 2002 when it bulldozed gravel into Gilbert Point, pinching off Russell Fiord’s link to the sea and creating the largest glacier-dammed lake in the world. Before the gravel dam broke, water within the lake rose more than eight inches each day and threatened to spill into a world-class steelhead stream near Yakutat.

Hubbard Glacier has been thickening and advancing since scientists first measured it in 1895. After the glacier dammed the fiord in 1986, the new Russell Lake rose 83 feet above sea level before the ice-and-gravel dam broke. In 2002, Russell Lake reached 49 feet above sea level before the dam burst and the water rejoined the ocean with a flood 30 percent greater than the largest measured flow of the Mississippi River at Baton Rouge.

If the plug of Hubbard Glacier again holds fast against Gilbert Point (as old river channels say it last did in about 1860), rainfall and glacial melt would fill Russell Lake until it reaches about 132 feet above sea level. Then, the water would spill over into an old channel of the Situk River, and flow from the river to the Gulf of Alaska. The Situk, now a clear-running stream with the highest population of wild steelhead in Alaska and possibly the world, would become a glacial stream that could be as large as the lower Snake River in Idaho.

Here's a good map of the area:

Here's where you can monitor the glacier.
