Scott Snowden Contributor. This photograph of the same location dates from August 12, 2005. In the early 20th century, the glacier met the water … The concerned experts claim the catastrophic event could even happen within the next 12 months if melting ice triggers a landslide of unstable rocks. Eklutna Glacier is a land terminating glacier in Chugach State Park and the Chugach Mountains near Anchorage, Alaska. CORVALLIS, Ore. – New acoustic observations mapping the changing face of the LeConte Glacier in southeast Alaska show that the rate of submarine melt is much higher than previously predicted by scientific theory, a new study published today in the journal Science shows. Alaskan glaciers get much of the attention in North America because Alaska is warming faster than the continental US. Pedersen Glacier is an outlet glacier of the Harding Icefield in Kenai Fjords National Park near Seward, Alaska. Little Holgate Glacier has separated into several smaller ice masses and Holgate's terminus, while still tidewater, has retreat from the field of view. In the 104 years between photographs, Reid Glacier has retreated about 3 kilometers (1.9 miles) and is just visible at the head of the fiord on the left side of the field of view. A well-developed trimline is visible on the west side of the glacier. The hillside in the foreground is covered with dense vegetation, including both conifers and deciduous trees. It was said to have reached 1,720 feet tall and the impact was compared to an atomic bomb by eye-witnesses. A pair of northwest-looking photographs taken from about 8 kilometers (5 miles) north of the mouth of McCarty Fjord, Kenai Fjords National Park, Alaska. A few icebergs of various sizes are floating in the water in front of the glacier. You can also see otters and seals in the lagoon. In the 2005 photograph, Muir Glacier is no longer visible, as it has retreated more than 50 kilometers (31 miles). In the roughly 105-110 years between photographs, Muir Glacier has retreated more than 50 kilometers (31 miles) and is completely out of the field of view. The 1909 photograph by USGS Geologist U.S. Grant shows the west side of the terminus of the then retreating McCarty Glacier, a tidewater glacier. The pair documents changes that have occurred during the 85 years between June 1919 and August 2004. An island and a large area of glacially sculpted bedrock have emerged from beneath the retreating glacier. The Taku Glacier, located north of Juneau, Alaska, has started to retreat as temperatures rise. The potential disaster was warned about in May by scientists who wrote an open letter to the Alaska Department of Natural Resources (ADNR). This suggests that retreat and thinning began in the mid- to late-19th century. Vegetation, predominantly alder, covers much of the lower slopes on the opposite side of the inlet. Geophysicist Chunli Dai from the Ohio State University told NASA’s Earth Observatory: “It was hard to believe the numbers at first. Frst night we camped right by Aialik Glacier (heard awesome "thundering" noises from the glacier), second night by Holgate Glacier (with humpback whales swimming by!). Sitemap The Harding Icefield glaciers that drain east are in the Kenai Fjords National Park, which has a monitoring program. The 2004 photograph documents the continued thinning and retreat of East Fork Teklanika Glacier. The total melting during this period added about half an inch to global sea levels—enough to cover the United States with a layer of water one-and-a-half feet thick. Prince William Sound is a remote area but its surrounding waters are often frequented by boats, including cruise ships. Pedersen Glacier, 1920-1940 A view looking north toward Pedersen Glacier, Kenai Mountains, Aialik Bay, Alaska, taken from the west shoreline of Aialik Bay. The Pedersen Glacier in Alaska has completely vanished over the past 90 years. Little, if any vegetation is present in the photograph. Our family of four (parents, sons ages 13 and 16) did a two-night kayak trip with Jamie from KAW. Some icebergs, evidence of recent calving, can be seen floating in Muir Inlet. The spy who shagged 'em: Suspected Chinese agent reportedly slept with, courted pols, Grinding to a halt: 'Highest-earning sex worker’ sues over lost wages, 2020 is so awful, even the aliens are staying hidden, NYC Chipotle besieged by rats feasting on avocados, biting employees, Warning issued about COVID-19 vaccine after patients suffer reaction. If it’s not that soon, they think the ‘mega-tsunami’ is likely to happen within the next two decades. Little Holgate Glacier terminates at the shoreline. Several dozen dead trees are remnants of a mid-20th century forest that was drowned by more than 3 meters (9.8 feet) of down warping of the coast during the 1964 Alaskan Earthquake. We had a beautiful view of the glacier from our cabin porch with two rocking chairs, as well as the dining room and the sitting area in front of the main lodge.I would go out and just sit on the rocker and gaze at the Pedersen lower lagoon, and the glacier. The World’s Glaciers Continue To Melt As Massive Chunk Of Arctic Ice Cap Breaks Off. In the roughly 60-80 years between photographs, most of the lake/lagoon has filled with sediment and now supports several varieties of grasses, shrubs, and aquatic plants. Science. Note the large trees. Opinions expressed by Forbes Contributors are their own. But the glacier has gradually melted away through the 20th century. Melting Alaska glacier could unleash ‘mega-tsunami’ this year The tributary no longer makes contact, having retreated more than 0.6 kilometers (0.37 miles) up the valley wall. A stream of icebergs issues from several embayments cut into the approximately 45 meter (148 feet) high face on the east side of the terminus. Muir Inlet, pictured in a late 19th century photograph, actually a postcard. Estimates suggest that the glacier once measured as much as 164 feet thick. Field, # 41-64, courtesy of the National Snow and Ice Data Center and Glacier Bay National Park and Preserve Archive). The retreat began in the 1800s when Alaska was still Russian territory. It’s one of thousands in North America that are losing ice as … Pedersen Glacier a glacier in Alaska. A view looking north toward Pedersen Glacier, Kenai Mountains, Aialik Bay, Alaska, taken from the west shoreline of Aialik Bay. Mar 22, 2018 - The image here shows two photos of the Pedersen Glacier in Alaska. Note the abundant vegetation on the near-ground slopes on the east side of Muir Inlet and in the lower part of Adams Inlet. A large accumulation of snow sits on the valley floor adjacent to where the northern-most hanging glacier tributary previously joined Toboggan Glacier. Pedersen Glacier, at Aialik Bay in Alaska’s Kenai Mountains, in 1917 (left) and 2005 (right). Note the lack of floating ice and the abundant vegetation on many slopes throughout the photograph. I found those photos in this YouTube video after viewing a short video about how warm it is in the Arctic Circle this year, where glaciers are melting during the winter instead of forming new ice. In the 96 years between photographs, the terminus of Aialik Glacier remains close to its 1909 position, retreating a maximum of 300 meters (984 feet) and thinning 20-50 meters (65.6-164 ft). During the intervening 69 years between photographs, Yale Glacier has retreated as much as 6 kilometers (3.7 miles), with most of the retreat occurring post-1957. Also ventured to Pedersen Glacier via the lagoon and had lunch. Alder has become established on the hill slopes. In places, more than a 1.0 kilometer (0.62 mile) thickness of ice had been lost. Retreat of the land-based western portion of the terminus has kept pace with the retreat of the eastern tidewater portion of the glacier. The region's permafrost, ground that is perpetually frozen, is thawing in Alaska's interior, and pockets of underground ice trapped in the frost are melting with it. A 1958 landslide in the region resulted in what’s often referred to as the tallest tsunami wave in modern times. Pedersen Glacier, at Aialik Bay in Alaska’s Kenai Mountains, in 1917 (left) and 2005 (right). - Pedersen Glacier, located in Kenai Fjords National Park, receded throughout the 20th century, exposing Pedersen Spit and Pedersen Lagoon. This photograph of the same location dates from August 10, 2005. This pair of oblique aerial photographs of Yale Glacier, Chugach Mountains, Chugach National Forest, Alaska, documents changes that occurred during the 69 years between June 1937 and July 28, 2006. Privacy Notice Note the absence of any identifiable vegetation and the numerous bare bedrock faces present on both sides of the glacier (W. O. The first photograph is an undated summer view, probably dating from between the mid-1920s and the early 1940s. “This tsunami could impact areas frequented by tourists, fishing vessels, and hunters (potentially hundreds of people at one time). A visitor center operated by the U.S. Forest Service is open year-round with spectacular views and interactive exhibits, plus you’ll find great hiking to waterfalls and overlooks for photography. Numerous icebergs, some more than 2 meters (6.6 feet) in diameter are grounded on the tidal flat in the fore- and middle-ground of the photograph. A photographer and seven tourists are exploring the icebergs. Runoff from Eklutna Glacier contributes to Eklutna Lake, the main source of drinking water for the Anchorage community as well as hydroelectric power via the Eklutna Hydroelectric Project. These north-looking photographs, all taken from about the same offshore location, about 0.5 kilometers (0.3 miles) north of Toboggan Glacier, Harriman Fiord, Prince William Sound, Chugach National Forest, Alaska. This photo and the one that follows were taken from the same location on the west shoreline of Muir Inlet, Glacier Bay National Park and Preserve, Alaska, and show the changes that have occurred to Muir Glacier during the 113 years between September 1892 and August 2005. The 1909 photograph by USGS Geologist U.S. Grant shows Holgate Glacier, a tidewater glacier at the head of the fiord with Little Holgate Glacier, one of its former tributaries, located to its left. All of the eastern tributaries have retreated and lost contact with Yale Glacier. Thanks for contacting us. The glacier has thinned as much as 150 meters (492 feet) and retreated more than 0.5 kilometers (0.3 miles). Pedersen Glacier, located in Kenai Fjords National Park, receded throughout the 20th century exposing Pedersen Spit and Pedersen Lagoon. They calculate that Alaska's glaciers and frozen rivers are melting fast enough to cover the whole state with 30 centimeters of water (nearly a foot) every seven years. “Surviving villagers still have not returned because a nearby slope is deforming and threatening to fail. About In Kenai Fjords National Park, trends ESE to Aialik Bay N of Holgate Head, 20 mi. It could mean a slow moving landslide is already taking place but if a large part of the mountain slope gave way it could have dire consequences. The researchers’ findings are available on the ADNR website. The angular rocks in the foreground are part of a cobble lag deposit winnowed from sediment previously deposited by Muir Glacier and by melting grounded icebergs. Over the years, Pedersen Glacier has steadily retreated towards its Harding Icefield source and out of the field of view in this photo. The tidal flat is probably ice cored, underlain by glacier ice. Its terminus, a thin tongue of ice, can be seen surrounded by a mass of debris. This 2004 photograph documents the retreat of McCarty Glacier from the field of view, a retreat of more than 15 kilometers (9.8 miles). The shallow water adjacent to the shoreline in the foreground appears to be covered by a small thickness of sea ice, containing a number of pieces of brash ice. A pair of northwest looking photographs, both taken from the same location on the southwest side of Reid Inlet, Glacier Bay National Park and Preserve, Alaska, showing the changes that have occurred to Reid Glacier during a period of more than a century, between June 10, 1899 and September 6, 2003. Watch an alaskan glacier melt In Seward, Alaska, Exit Glacier is melting at an astonishing rate. Riggs Glacier has retreated as much as 0.6 kilometers (0.37 miles) and thinned by more than 0.25 kilometers (0.16 miles). This location was being used for subsistence hunting by local Native Alaskans. Glacier National Park is replacing signs that predicted its glaciers would be gone by 2020 By Christina Maxouris and Andy Rose, CNN Updated 3:09 PM ET, Wed January 8, 2020 SW of Seward, Chugach Mts. An unprecedented ‘mega-tsunami’ could be caused by a melting Alaska glacier, scientists have warned. The black and white image is from 1917, and the open green field is from 2005. The ice thickness in the center of the photographs is more than 0.7 kilometers (0.43 miles). “The unstable slope in Barry Arm is much bigger than either of these examples, and thus has the potential to produce a larger tsunami that could have impacts throughout Prince William Sound.”. The retreat of the majority of mountain glaciers worldwide is one of the clearest signs of long-term climate change. 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. It is the easiest glacier to visit in Southeast Alaska, and one of the most popular glaciers in the state. During the 113 years between photographs, Muir Glacier ceased to have a tidewater terminus. Pedersen Glacier's terminus has retreated more than 2 kilometers (1.24 miles). The width of the tidewater part of the terminus of the glacier is much less than half of what it was in 1937. Isolated patches of snow are present at a few higher elevation locations. Note the stands of trees that have developed between the sediment filled wetland and the glacier. Ongoing monitoring will continue so that scientists can spot warning signs of a landslide and subsequent tsunami before it happens. The hillside in the foreground is covered by a few centimeters (inches) of snow. We've received your submission. Do Not Sell My Personal Information, Your California Privacy Rights In the 1980s, the lagoon was designated as the Pedersen Lagoon Wildlife Sanctuary, a 1,700-acre sanctuary meant to preserve and protect the area's wildlife and land. Do Not Sell My Personal Information. The 1892 photograph shows the more than 100 meter (328 feet) high, more than 4 kilometers (2.5 miles) wide tidewater terminus of the glacier with a face capped by angular séracs. Glaciers are rivers of ice. Except for the moraine-covered ice on both margins of the glacier, snow still covers most of the lower reaches of the glacier. The southernmost named glacier among them is the Lilliput Glacier in Tulare County, east of the Central Valley of California. Northwestern Glacier spans most of the width of the photograph. Underwater glacier melt could be happening faster than previously thought, a dangerous finding as melting ice and glaciers raise sea levels. This 1941 photograph shows the lower reaches of Muir Glacier, then a large, tidewater calving valley glacier, and its tributary, Riggs Glacier. Details. Alaska’s Muir Glacier, like many Alaskan glaciers, has retreated and thinned dramatically since the 19th century. No trees are present on the hillside or on any other surface in the field of view. “We believe that it is possible that this landslide-generated tsunami will happen within the next year, and likely within 20 years.”. By 2005, the glacier had retreated, leaving behind sediment allowed the lake to be transformed into a small grassland. Terms of Use The second photograph dates from August 12, 2005. 72,659, This story has been shared 52,757 times. The 1919 photograph by USGS Geologist Stephen Capps shows the then retreating, debris-covered terminus of East Fork Teklanika Glacier, with an elevated lateral moraine on its west (left) side. “The resulting tsunami reached elevations of 633 feet near the landslide, and 35 feet 15 miles away. The glacier has retreated more than 0.3 kilometers (0.19 miles) since 1919, retreating at an average rate of about 4.0 meters (13 feet) per year. “At Karrat Fiord, west Greenland, a landslide in June 2017 similarly produced a tsunami that killed four people and destroyed a large portion of the town of Nuugaatsiaq, 20 miles away. Minimal vegetation existed on the fiord-facing hill slopes. The researchers said: “Landslides have set off giant waves elsewhere in Alaska and Greenland during the past decade. The 1899 photograph is taken towards the northwest and shows the approximately 60 meter (197 foot) high tidewater terminus of the then retreating Reid Glacier. In 1966, a team of U.S. Geological Survey scientists journeyed to two small glaciers in Alaska to dig snow pits needed for measuring snow depth and … Scientists from the University of Alaska and the U.S. Geological Survey estimate that Alaska is losing ice at the rate of 75 billion metric tons a year. Among other glaciological research, mass balance measurements of Gulkana Glacier began in the early 1960s with the University of Alaska Gulkana Glacier Project (Péwé and Reger, 1983).In 1966 the USGS began direct measurements of surface mass balance, which, after a decade of dense spatial sampling, were reduced to three "index" sites distributed across the elevation range of Gulkana Glacier. Yale Glacier has thinned substantially, in places by more than 250 meters (820 feet). Note the dense vegetation that has developed on the till cover of White Thunder Ridge. Both photographs are taken towards the north and show the retreating, calving, tidewater terminus of Yale Glacier, located at the head of Yale Arm, College Fiord, Prince William Sound, Alaska. The glaciers we see today in the park are increasingly small remnants of their former selves, but all around us we can see evidence of how they dominated the landscape. The early photograph shows the more than 100 meters (328 feet) high tidewater terminus of the glacier with a face capped by angular séracs. No icebergs are visible. These scientists have predicted that the tsunami could cause issues over 10 miles away so a pre-warning could save lives. New photos released by NASA this week show that the melting of Taku has at last become visible. The glacier drops quickly from the plateau of the icefield through a pair of icefalls terminating in a lake at 25 meters above sea level. Pedersen Glacier’s terminus is no longer in the field of view and has retreated more than 2 kilometers (1.2 miles) to the west. 197,841, This story has been shared 72,659 times. The Greenland ice sheet is about the same size as the state of Alaska and 10,000 feet thick in places. The tides in this area are greater than 3 m (9.9 feet). See separate review for details. Your Ad Choices Spent 3 nights at Kenai Fjords National Park. The pair documents significant changes that occurred during the 95 years between July 24, 1909 and August 13, 2004. “In Taan Fiord (Icy Bay, Alaska), a landslide that began moving slowly decades ago suddenly failed in October 2015. This story has been shared 197,841 times. The findings suggest scientists may need to consider additional factors when predicting ice melt in glacier When photographed, the glacier was retreating and had a sérac-capped terminus that ranged from 20-50 meters (65.6-164 feet) high. A pair of northwest looking photographs of Aialik Glacier, Kenai Fjords National Park, Kenai Mountains, Aialik Bay, Alaska, both taken from the same location on the northwest shoreline of Squab Island. The tributary located high above Pedersen Glacier separated from it sometime during the third quarter of the 20th century. The scientists wrote: “We, a group of scientists with expertise in climate change, landslides, and tsunami hazards, have identified an unstable mountain slope above the toe of Barry Glacier in Barry Arm, 60 miles east of Anchorage, that has the potential to fail and generate a tsunami. I did it for the sole purpose of helping educate and communicate about the world's big climate change problems so that more might take action before it's too late.

Several dozen dead trees are remnants of a mid-20th century forest that was drowned by more than 3 meters (9.8 feet) of down warping of the coast during the 1964 Alaskan Earthquake. The 2004 photograph documents the continuing retreat of both glaciers. ... Tongass National Forest in Alaska. Pedersen Glacier is in Aialik Bay and terminates in a proglacial lake before the ocean. It contains enough ice to raise sea levels by 23 feet (7 meters). This is a list of glaciers existing in the United States, currently or in recent centuries.These glaciers are located in nine states, all in the Rocky Mountains or farther west. The pair documents significant changes that have occurred during the 95 years between July 30, 1909 and August 11, 2004.

A pair of northwest-looking photographs taken from near the head of Holgate Arm, Aialik Bay, Kenai Fjords National Park, Alaska. The first photograph by U.S. Grant, is a July 20, 1909 view of the then slowly retreating western part of the terminus. This region has seen glacier retreat, which has led to instability on the slopes of a mountain in Barry Arm above the Barry Glacier. Satellite images have shown how ice melt on the glacier has left a large rocky area exposed. Photographs taken at the same locations decades apart reveal just how dramatically Alaska's glaciers are melting and retreating. The 1905 photograph shows that Toboggan Glacier was thinning and retreating and was surrounded by a large bedrock barren zone. Mount Hunter in Denali national park, is seeing 60 times more snow melt … 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.

The photographs document significant changes that have occurred during the 103 years between August 20, 1905 and August 22, 2008. No vegetation is present at the head of the fiord. My name is Randy Richards, and I created this series of digital iceberg images in my digital art style. Sedimentation and uplift have expanded the shore area and produced a marshy wetland covered by a diverse array of vegetation. Muir and Riggs Glaciers filled Muir Inlet. In the roughly 60-80 years between photographs, Northwestern Glacier has retreated out of the field of view. In the early 20th century, the glacier met the water and calved icebergs into a marginal lake near the bay. The 2000 photograph documents that after 95 years, the glacier is still thinning and retreating. A pair of north-looking photographs, both taken from the same location near the retreating unnamed valley glacier that forms the East Fork of the Teklanika River, Denali National Park and Preserve, Alaska. 52,757, © 2020 NYP Holdings, Inc.
