She works for the Conservation Land Trust and is helping the Argentine government — which is coping with some of the same climate issues that face Alaska — expand its own national park system. From the Exit Glacier parking lot it’s an easy walk to the overlook. In Kenai Fjords National Park, Exit Glacier was a popular attraction for just this reason. Since 2011, average October-to-May daily temperatures at the glacier's low elevations have been above freezing about half the time, the report noted. While glacial melt is swelling the volume in the creek and is making the area more watery in general, it turns out that the modern melt is likely not responsible for the sudden inundations that have forced road closures in recent years, a new study finds. Now climbers are instructed to carry out their waste, but past years' deposits, after being churned through the moving and melting ice, are now turning up at the end of Exit, she said. Your subscription to “If you went to a place on a glacier and scraped the algae away, about 20 percent of the melting would go away,” said Roman Dial, a biologist at Alaska Pacific University. For repeat visitors, the changes are stark, said Sharon Kim, chief of resources at Kenai Fjords. The study examined bones from nine individual fish, six from the archaeological sites and three from modern times. A new management plan for the park's front country — the Exit Glacier area — is in the works to address that. When the National Park Service built it in 1987, it offered a sweeping view of the glacier. There are some glaciers you can drive to, but very few that you can stroll to. The Park Service has a mass-balance monitoring program that takes measurements each spring and fall to compare the icefield's annual snow accumulations with annual melts. The Park Service has launched a research project to track acidification in Kenai Fjords' marine waters, along with other characteristics like salinity, temperature and turbidity. "I remember walking over here," Shippey said. The original estimates of the timing of glacier melt were based on two things: modeled projections of the glaciers’ response to warming, and direct observations of glacial retreat. Much longer-term geologic processes are at work, the study concludes. "Most science that you're doing, you may be measuring inches, centimeters, millimeters," Kim said. Yereth Rosen was a longtime reporter for Alaska Dispatch News. In late summer 2010, researchers recorded daily images of Exit Glacier that captured and revealed glacial flow, thinning, melt, and the phenology of the nearby flora. Exit Glacier, which the Park Service says got over 181,500 visitors last year, is not Alaska's only walk-up glacier, albeit with a walk that has been getting longer as the glacier shrivels. It has starred on television and video, including an episode of NBC's "Running Wild with Bear Grylls" that focused on Obama's visit. The group used the glacier to exit the icefield, and the name stuck. That adds to the acidification as marine waters absorb more atmospheric carbon. An unpleasant trend: Park workers monitoring the glacier's retreating edge from 2013 to 2016 retrieved bags of human feces, with contents in fairly fresh condition, said Deborah Kurtz, physical science program manager at Kenai Fjords. Stay informed about the latest scientific discoveries & breakthroughs. Renee Shippey of Dallas, who visited Kenai Fjords in June and had been there in 2006 as well, was sorry that her granddaughter was unable to get the same close-up view of blue ice that was available 11 years ago. That was part of the fun, standing on a centuries-old freeze, peering into blue crevasses. Exit Glacier, a finger of cracked, blue-white ice that drops out of 700-square-mile Harding Icefield, some of it outside the park, is relatively small, only 14 square miles. ... That means run-off from melting glaciers and ice-caps is raising sea … There was no snow, no ice, reasonable temperatures but that didn't matter. Thick stands of alder with some willow come next, followed by black cottonwood forest that slowly gives way to shade-tolerant mountain hemlock. The meandering, braided creek and river channels that run down from the end of the glacier to the Seward Highway — and along the corridor that holds the road — are typical of the unstable waterways left behind after a glacier retreats. There will be no more extensions, Kim said, because the toe of the glacier is now surrounded by steep and treacherous terrain. The swift retreat of Exit Glacier, in Alaska’s Kenai Mountains, offers a clear sign of how climate change can affect a region in a very short time. The oxygen molecules in the fish ear bones, or otoliths, carry a record of life history. How long before the tourists stop coming to Exit Glacier, I wonder. Exit Glacier Guides offers visitors to Seward, AK a chance to see a unique natural wonder close-up - and since it takes a little work to get there - our groups see it without a crowd. The marker for 1917 is about a mile from the glacier’s current point. (Marc Lester / Alaska Dispatch News). This is our second visit in three years. What does the public expect us to do, within a reasonable parameter?" Reporter Simon Montlake was fully expecting to be disappointed by Exit Glacier, and he was not disappointed. President Barack Obama visited Exit Glacier in 2015. Isotope analysis of bones found from archaeological sites and of modern cod bones points to a temperature increase in that part of the Gulf of Alaska of 3.6 to 5.4 degrees Fahrenheit, according to a study published recently in the Journal of Archaeological Sciences: Reports. If you have questions about your account, please Science Monitor has expired. "I'm shocked it changed this much," said Julie, with her husband and two daughters at the trail summit. Pedersen Glacier lost an average of 65 feet a year from 1951 to 1986, but that rate jumped to 410 feet a year from 1994 to 2015, scientists report. But where the road is concerned, "It turns out to be of secondary importance at Exit Glacier.". or call us at 1-617-450-2300. Today it’s a lovely spot. I look for cobalt blue but all I see is grey and white, a frozen pack of rock and ice, cracked and bruised. Over the year ending Oct. 1, after fall measurements were taken, the retreat was 293 feet, according to the National Park Service. An update on major political events, candidates, and parties twice a week. The road to Exit Glacier is supposed to be open until 01-Nov but the parks department decided to close it sometime before 29-Oct for no reason. Rode with "Mean Gene" - very economical compared with the Cruise Ship excursions! Exit's rapid changes have forced the Park Service to make frequent adjustments along the trail system. But it stands out for its location in an easily accessible national park, the in-your-face documentation of its retreat and its role as a real-time climate change laboratory. Hear about special editorial projects, new product information, and upcoming events. The cruise-ship excursions, the Anchorage day-trippers, will they go elsewhere? An Alaskan couple stops at the pavilion to talk. Alaska's temperature has risen by four degrees Fahrenheit in the last 50 years, that's compared with two degrees for rest of the planet, leading to melting glaciers. "We just can't continue to extend the trail any longer without it being really unsafe," she said. The president trekked up Exit Glacier on Tuesday as part of his three-day tour in the state to campaign for climate awareness. There are plans to expand the study and analyze more old fish bones from a wider part of the Gulf of Alaska, he said. That's what I kept telling her: 'You're going to see the blue. "Here, people just have to visit it again in a year or two.". subscription yet. What happens then to the park infrastructure built for visitors to a glacier that is creeping out of view, year by year? For Sofia Heinonen, visiting from Argentina's glaciated Patagonia region, Exit Glacier and the Park Service's management of it prove good lessons for her country.
