14). If the glacier that originates near Mount Logan in the Yukon continues advancing at its current rate, it could block access to a fiord in Alaska and "strongly impact" the nearby ecosystem. The Advance of Hubbard Glacier Since measurements began in 1895, Alaska’s Hubbard Glacier has been thickening and steadily advancing into Disenchantment Bay. This Glacier is actually advancing (growing, the only one that still is by the way) so don't be too mad about the people being excited for the ice falling Pseudonyms will no longer be permitted. Hubbard Glacier Unlike the vast majority of glaciers, Hubbard Glacier has been both thickening and advancing since the International Boundary Commission first mapped it in 1895. Russell Fiord, Alaska, Peak discharge of Mississippi R. at Memphis, Hubbard Glacier is the largest tidewater glacier on the North American continent. Williams says the Situk River would eventually stabilize enough so fishers could access it again and says it could even increase the fish yield in the long run by creating more spawning habitat. 4) To encourage thoughtful and respectful conversations, first and last names will appear with each submission to CBC/Radio-Canada's online communities (except in children and youth-oriented communities). This image, acquired by the Operational Land Imager (OLI) on Landsat 8, shows Hubbard Glacier on July 22, 2014. Comments are welcome while open. the average rate of 0.7 feet per day in both 1986 and 2002 (fig. If you have Adobe Acrobat Reader installed on your computer, you may view and/or print the PDF version of this report. However both the 1986 and 2002 dams failed (fig. 6). preliminary forecast of the advance of Hubbard Glacier and its influence on has twice closed the entrance to Russell Fiord during the last 16 years by squeezing were growing. The area is an extremely active and dynamic landscape with an advancing tidewater glacier (10 km wide at tidewater), two major seismic faults, and a maximum net isostatic uplift rate of 0.44 cm/yr. Water flowing into the cutoff The advance runs counter to so many thinning and retreating glaciers nearby in Alaska and around the world. The advance runs counter to so many thinning and retreating glaciers nearby in Alaska and around the world. Advance of Hubbard Glacier In this picture you can see two moose who swam out to this small outcropping. Photo by Rod March, U.S. Geological A push moraine is sediment bulldozed from the floor of Russell Fiord by the advancing ice. Part of Hubbard Glacier has been advancing into Disenchantment Bay for more than 100 years, according to NASA's Earth Observatory. "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. This image, acquired by the Operational Land Imager (OLI) on Landsat 8, shows Hubbard Glacier on July 22, 2014. This is in stark contrast with most glaciers, which have thinned and retreated during the last century. Hubbard Glacier Facts. (fig. The Hubbard Glacier has been advancing for about a century. Even still, Hubbard is still an advancing glacier. "The Army Corp of Engineers special Web site for the Hubbard Glacier - www.glacierresearch.com - contains some absolutely amazing photos of the advancing glacier… We took a small boat to get close to the Hubbard Glacier. The 1986 closure occurred near the first of June; the 2002 closure was gradual Pio XI Glacier, the largest glacier of the Patagonian ice field, has been advancing for years, says reader J Philip Petersen. Closed Captioning and Described Video is available for many CBC shows offered on CBC Gem. It has been thickening and advancing toward the Gulf of Alaska since it was first mapped by the International Boundary Commission in 1895 (Davidson, 1903). According to the National Park Service, the advance is due to global warming which causes more precipitation to fall in the St. Elias Mountains. 8). Fiord is much more certain. 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. Hubbard Glacier has been thickening and steadily advancing into Disenchantment Bay. feet below sea level down Disenchantment Bay. The glacier begins on Mount Logan, located in Canada, and stretches for 122 kilometers into the US. If a glacier that originates near Mount Logan in the Yukon continues advancing at its current rate, it may block access to a fiord in Alaska and "strongly impact" the nearby ecosystem. While most glaciers are receding, Hubbard Glacier is actually an advancing tidal glacier! The advance runs counter to so many … calve over relatively shallow submarine moraines, and have unusually small ablation July 22, 2014 JPEG. Hubbard Glacier has been advancing for more than 100 years and It is slowly but constantly moving toward the Gulf of Alaska through Disenchantment Bay. Although the timing is uncertain, the prospect near Yakutat, Alaska, 1986: U.S. Geological Survey Open-File Report 86–545, This atypical behaviour is an important example of the calving glacier cycle in which glacier advance and retreat is controlled more by the mechanics of calving than by climate fluctuations. Mayo, L.R., 1989, Advance of Hubbard Glacier By submitting a comment, you accept that CBC has the right to reproduce and publish that comment in whole or in part, in any manner CBC chooses. 2. Since measurements began in 1895, Alaska's Hubbard Glacier has been thickening and steadily advancing into Disenchantment Bay. Hubbard Glacier, Russell Fiord and the Situk River near Yakutat, Alaska are glacial terrains and forelands in a constant state of motion. In 2002 the advancing terminus of Hubbard Glacier created a glacier lake dam which turned Russell Fiord in to a lake for about two and a half months. All of these glaciers calve into the sea, are at the heads of long fiords, have undergone retreats during the last 1,000 years, calve over relatively shallow submarine moraines, and have unusually small ablation areas compared to their accumulation areas. The image above, acquired by the Operational Land Imager (OLI) on Landsat 8, shows Hubbard 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. In contrast to many other glaciers around the world, it has been “advancing” ever since its discovery. As the precipitation cools, it turns into snow—the reason for Hubbard Glacier’s advance. of water per second (ft³/s). and was complete about June 16. A rainstorm caused a rapid lake fiord from mountain streams and glacier melt causes the level of Russell Lake It has been thickening and advancing toward the Gulf of Alaska since it was first mapped by the International Boundary Commission in 1895 (Davidson, 1903). The longest closure, in 1986, lasted about five months and caused fiord levels to rise 25 metres, according to Williams. The 1986 dam failed catastrophically during the night of October 8 (fig. The fiord bottom lies 5). The glacier isn’t surging right now, but it’s likely due to surge again soon – there were two instances in the past 100 years (1986 and 2002) when Hubbard Glacier blocked Russell Fjord from draining with its calving ice shards and advancing moraine. The advance runs counter to so many thinning and retreating glaciers nearby in Alaska and around the world. A lot. Ablation: All processes by which snow and ice are 7). Report 90–4172, 34 p. Wrangell-St. Elias National Park and Preserve. In addition to its forward movement, the glacier has been thickening as well. David Williams, project manager of the Yakatat watershed study for the U.S. Army Corps of Engineers, estimates it would take about a year for water levels in the dammed fiord to rise 40 metres, at which point glacial meltwater would overflow into the Situk River. He says they won't know for sure until it happens. The growth of the moraine dam (25 percent larger than Rhode Island), advanced across the entrance to 35-mile-long In May 1986, the Hubbard Glacier advanced into the sea, blocked the entrance to the Russell Fjord and hence formed Lake Russell. The advance runs counter to so many thinning and retreating glaciers nearby in Alaska and around the world. … also increased the rate of erosion of the dam. Alaska’s Hubbard Glacier. "It will be catastrophic for those who presently fish the Situk under its present conditions because it will change the conditions drastically.". Russell Fiord (fig.1) during June 2002, temporarily turning throughout the Little Ice Age (AD1350 or 1450 to AD1900) when most glaciers 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. The glacier is accumulating mass near its origin faster than it's losing it in the ocean. Not only will this change dynamics for fish and wildlife in the area, it could make it difficult and dangerous for fishers to access the river. However, relatively small amounts of lake water overflowed the 2002 Hubbard Glacier is the largest of eight calving glaciers in Alaska that are currently increasing in total mass and advancing. Unlike most glaciers, which are receding, Hubbard Glacier is advancing into Disenchantment Bay, giving it the nickname of the galloping glacier. This observation suggests that the damming moraine was being squeezed higher In the spring of 1986, as the glacier's terminus was entering shallow water near Osier Island and the entrance to Russell Fiord, its calving rate decreased and the Valerie Glacier tributary to the Hubbard underwent a brief surge. The advancing terminus of Hubbard Glacier is in the foreground. 2. Growing. These two floods are the largest recorded glacial-lake outburst flood events Since measurements began in 1895, Alaska’s Hubbard Glacier has been thickening and steadily advancing into Disenchantment Bay. The river is heavily used by commercial fishers in Yakatat, which has a population of about 650 people. Hubbard Glacier, at the head of Disenchantment Bay near Yakutat, Alaska, is one of the advancing glaciers and is the largest calving glacier on the North American Continent. in total mass and advancing. Hubbard Glacier. The captain ofour ship, the Celebrity Millenium was great (a wonderful sense of humour). These measurements are constantly changing as the Hubbard Glacier continues to grow and move forward. The advance is caused by global warming, which causes more precipitation to fall in the St. Elias Mountains. Hubbard Glacier is defying the global paradigm of valley or mountain glacier shrinkage and retreat in response to global climate warming. with climate-driven glacier changes for a very long time. This constant movement (which is extremely slow and not noticeable to the human eye) is what contributes to the regular calving of Hubbard Glacier. The glacier begins on Mount Logan, located in Canada, and stretches for 122 kilometers into the US. 7) releasing a flood that rapidly accelerated to a maximum of about 4,000,000 Hubbard Glacier is currently advancing rather than retreating like many of its Alaska glacial neighbors. Hubbard Glacier is the largest tidewater glacier on the North American continent. It has been growing and advancing over the past hundred years. Glaciers around the world are in retreat, but not Alaska’s Hubbard Glacier. Dam failure released a flood that reached a maximum Hubbard Glacier, located in southeast Alaska, has an intriguing history; it retreated during the Little Ice Age when neighboring glaciers advanced and is currently advancing while neighboring glaciers recede [Barclay et al., 2001; Trabant et al., 2003; McNabb and Hock, 2014]. Since measurements began in 1895, Alaska’s Hubbard Glacier has been thickening and steadily advancing into Disenchantment Bay. July 22, 2014. Note the spray behind them which was caused by “calving” or the breaking off of ice chunks from the face wall. Russell Fjord has been temporarily blocked by the Hubbard Glacier twice in recent history but the closures did not last long enough to overflow the fjord. Just shortly after 10 am, we ventured to our new friends’ cabin [PH 6147] for the breathtaking entrance and viewing of the Hubbard Glacier. It is slowly but constantly moving toward the Gulf of Alaska through Disenchantment Bay. Audience Relations, CBC P.O. Large chunks of the glacier break off into the ocean on a regular basis. Hubbard Glacier has been … areas compared to their accumulation areas. preliminary forecast of the advance of Hubbard Glacier and its influence on Hubbard Glacier is the largest of eight calving glaciers in Alaska that are currently increasing in total mass and advancing. The area is an extremely active and dynamic landscape with an advancing tidewater glacier (10 km wide at tidewater), two major seismic faults, and a maximum net isostatic uplift rate of 0.44 cm/yr. The glaciers that 6). All of these glaciers calve into the sea, are at the heads of long fiords, have undergone retreats during the last 1,000 years, calve over relatively shallow submarine moraines, and have unusually small ablation areas compared to their accumulation areas." In this series of photos from June of 2002, Bruce Molnia of the USGS documented the advancing terminus of Hubbard Glacier and the channel cut into the top of its push moraine that blocked the mouth of Russell Fiord. closure. This image, acquired by the Operational Land Imager (OLI) on Landsat 8, shows Hubbard Glacier on July 22, 2014. If you do not have Acrobat Reader, you may download it here. 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. It's possible that the glacier could close the fjord by later this summer if the current rate speeds up, says Harris. Image taken on July 22, 2014 shows the advancement of Hubbard Glacier … Image taken on July 22, 2014 shows the advancement of Hubbard Glacier as compared to previous years. in the area. ft³/s, which occurred on August 13 in response to a 2-week-long rainstorm May 23, 2015 by Robert Hubbard Glacier has been advancing into Disenchantment Bay for more than 100 years, according to NASA’s Earth Observatory.

We reserve the right to close comments at any time. 2 and 3). in historical time (table 1). These surges were large enough to threaten the nearby coastal town of Yakutat, and they almost blocked the entrance to Russell Fiord, notes Alaska.org. As the precipitation cools, it forms snow. Valerie Glacier joins Hubbard from the northwest approximately 6-miles from the terminus. the heads of long fiords, have undergone retreats during the last 1,000 years, "It would need to warm a lot for Hubbard to start retreating, is what we're finding.

Hubbard is the longest tidewater glacier (meaning it ends at the ocean) in North America. Even if every glacier in Antarctica (per the study you cited) was advancing, this would still mean that most glaciers in the world are in retreat. Reggie Kirkovich, who owns a fishing charter company in Yakatat, says the last time it happened, every room in town was booked by news outlets, environmental groups and tourists wanting to visit the glacier and see the marine life trying to escape the freshwater fiord. Before it calves, the ice can be more than 400 years old! Hubbard Glacier Calving, on July 4th 2006. For example, Hubbard Glacier retreated about 38 miles between 1130 A.D. and 2 and 3).

This is a classic example of glacial advance due to snowfall far outpacing glacial calving and advancing when the climate is warmer, and then a retreat when the weather becomes cooler and there’s less snowfall. rise that increased the volume of water flowing over the moraine dam, which The glacier, which originates in the St. Elias Mountains of southwest Yukon, has been widely studied because of its enormous size and its proximity to the Alaskan community of Yakatat. above sea level throughout the 2002 closure period. It has been thickening and advancing toward the Gulf of Alaska since it was first mapped by the International Boundary Commission in 1895 (Davidson, 1903). As the largest advancing tidewater glacier in North America, Hubbard Glacier’s terminal face is the dramatic end of a process that began 450 years ago as snowfall on the slopes of Mount Logan. 10 May 09 – This from climatologist Cliff Harris of the Coeur d’Alene Press.

Located at the … Water fl owing into the cutoff Alaska’s Hubbard Glacier. The most spectacular is the Hubbard Glacier ( the largest glacier in NA.) lost from a glacier. The glacier's catchment basin extends into the Saint Elias Mountains, and snow that falls into this basin melts or flows into the terminus, facilitating Hubbard's growth. Hubbard Glacier is defying the global paradigm of valley or mountain glacier are added to a glacier. 3). 1). Stearns says the Hubbard Glacier is unusual because it has been steadily advancing for more than 100 years despite warmer temperatures. The World Glacier Monitoring Service is a database of 100,000 glaciers worldwide, 85% of which have retreated. feet at the glacier calving terminus, and then deepens again to as much as 750 The glacier is approximately 7 miles wide at its foot and 76 miles long. "The folks that were here said it was an absolute bonzana.". near Yakutat, Alaska, 1986, A The large calving glaciers that are currently advancing have been discordant The advance is caused by global warming, which causes more precipitation to fall in the St. Elias Mountains. Williams predicts the overflow would be mostly freshwater, because the denser salt water will remain on the bottom of the fiord. A Yukon glacier is slowly advancing towards an Alaskan river, setting the stage for an awesome collision of natural forces. 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. 18,700 ft³/s and the maximum rate was about 92,000 ft³/s, which occurred Advancing: Map of Hubbard Glacier. by glacier flow did not keep pace with erosion and the dam progressively failed calving glaciers, is far from being in equilibrium with climate. Valerie Glacier joins Hubbard from the northwest approximately 6-miles from the terminus. The maximum rate of inflow was about 44,000 Unlike the vast majority of glaciers, Hubbard Glacier has been both thickening and advancing since the International Boundary Commission first mapped it in 1895. The timeline is the "best guess" of assistant professor Leigh Stearns, whose research builds on decades of previous studies on the Hubbard Glacier. Hubbard Glacier is currently advancing rather than retreating like many of its Alaska glacial neighbors. 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. In addition to … Hubbard Glacier has been thickening and steadily advancing into Disenchantment Bay. into the lake can be calculated from the rates of lake level rise (fig. 7). 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. Named after Gardiner Hubbard, the Hubbard glacier is the largest tidewater glacier in North America. Box 500 Station A Toronto, ON Canada, M5W 1E6. Petersen is correct. According to the National Park Service, the advance is due to global warming which causes more precipitation to fall in the St. Elias Mountains. 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. Hubbard Glacier, Alaska, squeezes towards Gilbert Point on May 20, 2002.
