The glacier begins on Mount Logan, located in Canada, and stretches for 122 kilometers into the US. The advance is caused by global warming, which causes more precipitation to fall in the St. Elias Mountains. shrinkage and retreat in response to global climate warming. "It will be catastrophic for those who presently fish the Situk under its present conditions because it will change the conditions drastically.". During the 2002 closure, the average net inflow rate was about Large chunks of the glacier break off into the ocean on a regular basis. New research from the University of Kansas suggests the Hubbard Glacier could permanently dam the entrance to Russell Fiord, on the Gulf of Alaska, within 25 years. Hubbard Glacier. According to the National Park Service, the advance is due to global warming which causes more precipitation to fall in the St. Elias Mountains. Hubbard Glacier is a glacier located in eastern Alaska and part of Yukon, Canada, and named after Gardiner Hubbard. fiord from mountain streams and glacier melt causes the level of Russell Lake In May 1986, the Hubbard Glacier advanced into the sea, blocked the entrance to the Russell Fjord and hence formed Lake Russell. A rainstorm caused a rapid lake It is slowly but constantly moving toward the Gulf of Alaska through Disenchantment Bay. Unlike most glaciers, which are receding, Hubbard Glacier is advancing into Disenchantment Bay, giving it the nickname of the galloping glacier. The Hubbard Glacier is an active glacier with two major surges in the last 30 years, at one point advancing more than 7 feet a day. above sea level throughout the 2002 closure period. We reserve the right to close comments at any time. As the precipitation cools, it turns into snow—the reason for Hubbard Glacier’s advance.

Hubbard Glacier creates dam on Russell Fiord. Audience Relations, CBC P.O. … A push moraine is sediment that, in this case, has been bulldozed from the floor of Russell Fiord by the advancing ice. It’s kind of like Hubbard Glacier in Alaska (the largest tidewater glacier in North America) and Taku Glacier (the largest glacier in the Juneau Ice field), says Petersen. The longest closure, in 1986, lasted about five months and caused fiord levels to rise 25 metres, according to Williams. 7). “And all of them are either holding still, or advancing.” Source: Discovery. of the glacier continuing to advance and again blocking the entrance to Russell Hubbard Glacier is defying the global paradigm of valley or mountain glacier shrinkage and retreat in response to global climate warming. The push moraine that blocked the mouth of the fiord is located to the right of center. Located at the back of … 2 and 3). The fiord bottom lies But unlike nearly every other tidewater glacier on the continent, Hubbard is advancing, not retreating; it’s forever pushing a little further into the bay.

The advance runs counter to so many thinning and retreating glaciers nearby in Alaska and around the world. It is slowly but constantly moving toward the Gulf of Alaska through Disenchantment Bay. "When you have a river that's running relatively low flow and you increase [it] by anywhere between 20 and 50 times, it's not going to leave the bed of the river or the banks the same," says Williams. Hubbard Glacier has been thickening and steadily advancing into Disenchantment Bay. The glacier is advancing toward Gilbert Point near Yakutat at the astonishing rate of two meters (seven feet) per day! Williams predicts the overflow would be mostly freshwater, because the denser salt water will remain on the bottom of the fiord. May 23, 2015 by Robert Hubbard Glacier has been advancing into Disenchantment Bay for more than 100 years, according to NASA’s Earth Observatory.

Fiord is much more certain. 3). late in the 19th century (fig. Hubbard Glacier has advanced at a rate of about 80 feet per year since 1895 These measurements are constantly changing as the Hubbard Glacier continues to grow and move forward. Unlike the vast majority of glaciers, Hubbard Glacier has been both thickening and advancing since the International Boundary Commission first mapped it in 1895. Glaciers around the world are in retreat, but not Alaska’s Hubbard Glacier. Glacier is 95 percent of the entire glacier area and, like the other growing Part of Hubbard Glacier has been advancing into Disenchantment Bay for more than 100 years, according to NASA's Earth Observatory. A push moraine is sediment bulldozed from the floor of Russell Fiord by the advancing ice. Hubbard Glacier?s current advance began shortly before 1895 and has recently been newsworthy because its advance blocked the entrance to Russell Fiord between June and August 2002.
