Thunder Glacier is located on the northeast slopes of Buckner Mountain, North Cascades National Park in the U.S. state of Washington. [2] The glacier is approximately .10 mi (0.16 km) long and separated from the much larger Boston Glacier by an arete.
The Support Force Glacier is a major glacier in the Pensacola Mountains, draining northward between the Forrestal Range and Argentina Range to the Filchner-Ronne Ice Shelf.
Foggydog Glacier is a glacier between the Blank Peaks and Mount Rich in the Brown Hills of Antarctica. It was mapped by the Victoria University of Wellington Antarctic Expedition (1962–63) and so named because in plan the glacier is shaped like the head and neck of a dog, with a moraine suggesting a collar and a glacial lake in the position of the ears. Fog accumulates regularly over the glacier.
The UK Antarctic Place-Names Committee is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by SCAR.
Lützow-Holm Bay is a large bay, about 220 kilometres (120 nmi) wide, indenting the coast of Queen Maud Land in Antarctica between Riiser-Larsen Peninsula and the coastal angle immediately east of the Flatvaer Islands. It was discovered by Captain Hjalmar Riiser-Larsen in two airplane flights from his expedition vessel, the Norvegia, on February 21 and 23, 1931. The name honours Commander Finn Lützow-Holm of the Royal Norwegian Navy Air Service, a pilot for Captain Riiser-Larsen on the Aagaard in 1935.
Shirase Glacier is a large glacier entering Havsbotn, the bay that forms the head of Lutzow-Holm Bay in Antarctica. The area occupied by this feature was first mapped as a bay and named Instefjorden by the Lars Christensen Expedition (LCE) of 1936–37. Surveys by Japanese Antarctic Research Expedition (JARE) of 1957–62, revealed the large glacier in this position which they named after Lt. Nobu Shirase, leader of the Japanese Antarctic Expedition of 1911–12. Its nearby features were also charted and named by JARE unless otherwise noted.
Grinnell Glacier is in the heart of Glacier National Park in the U.S. state of Montana. The glacier is named for George Bird Grinnell, an early American conservationist and explorer, who was also a strong advocate of ensuring the creation of Glacier National Park. The glacier is in the Lewis Range and rests on the north flank of Mount Gould at an altitude averaging 7,000 feet (2,100 m), in the Many Glacier region of the park.
Blackfoot Glacier is the second largest of the remaining 25 glaciers in Glacier National Park, Montana. Blackfoot Glacier is just to the north of Blackfoot Mountain and near Jackson Glacier. The glacier was most recently measured in 2015 at 370 acres (1.5 km2), yet when first documented in 1850, the glacier also included the now separate Jackson Glacier and together, they covered 1,875 acres (7.59 km2). In 1850, there were an estimated 150 glaciers in the park. Glaciologists have stated that by the year 2030, all the glaciers in the park may disappear. However, under a modest increase in overall carbon dioxide levels, some glaciers will remain until the late 23rd century.
The Black Buttes, also known historically as the Sawtooth Rocks, make up an extinct stratovolcano in the Cascade Volcanic Arc in Whatcom County, Washington, United States. Glacially eroded remnants of this volcano rise above the Deming Glacier, part of the glacier system of the nearby volcano, Mount Baker. There are three major peaks — Colfax, Lincoln, and Seward — all of which can be climbed.
The Mariner Glacier is a major glacier over 60 nautical miles long, descending southeast from the plateau of Victoria Land, Antarctica, between Mountaineer Range and Malta Plateau, and terminating at Lady Newnes Bay, Ross Sea, where it forms the floating Mariner Glacier Tongue.
Isbrecht Glacier is a small glacier flowing south from Thurston Island in Antarctica between Cox Glacier and Hale Glacier. It was named by the Advisory Committee on Antarctic Names after JoAnn Isbrecht of the United States Geological Survey (USGS), Flagstaff, Arizona, a satellite image processing specialist who was part of the USGS team that compiled the 1:5,000,000-scale Advanced Very High Resolution Radiometer maps of Antarctica and the 1:250,000-scale Landsat image maps of the Siple Coast area in the 1990s.
Red Eagle Glacier is a glacier remnant (glacieret) in Glacier National Park in the U.S. state of Montana. The glacieret is a hanging glacier located on the north slope of Clyde Peak, and to the southeast of Mount Logan and Logan Glacier. Between 1966 and 2005, Red Eagle Glacier lost 53 percent of its surface area and now covers less than 25 acres (0.10 km2) which is below the threshold to qualify as an active glacier. Comparing images of the glacier taken in 1914 with those from 2009, indicates that the glacier has experienced extensive retreat.
Crosswell Glacier is a glacier 10 nautical miles long, flowing north-northeast from Mount Shinn between Sullivan Heights and Bearskin Ridge, in the central part of the Sentinel Range, Ellsworth Mountains, Antarctica. Together with Patton and Pulpudeva Glaciers, it enters Ellen Glacier northwest of Mamarchev Peak and southeast of Mount Jumper.
Hudman Glacier is a glacier draining south of Mount Landolt between Marze Peak and Miller Peak in Petvar Heights at the south end of the Sentinel Range, in the Ellsworth Mountains of Antarctica, flowing south-southeast to Minnesota Glacier. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1957–59, and was named by the Advisory Committee on Antarctic Names for Captain Rayburn A. Hudman, United States Marine Corps, who died in the crash of a Lockheed P2V-2n Neptune, modified for extreme range, flying in sub zero temperatures and Ski equipped for landing on the Ice runways at McMurdo Sound Antarctica on October 18, 1956.
McCance Glacier is the 30-km long and 5 km wide glacier draining the Hutchison Hill area on the west slopes of Avery Plateau on Loubet Coast in Graham Land, Antarctica. It flows north-northwestwards along the west side of Osikovo Ridge, Kladnitsa Peak and Rubner Peak and enters Darbel Bay.
Kornicker Glacier is a glacier draining northeastwards from the cirque bounded by Mount Liptak, Mount Southwick, Mount Milton and Mount Mullen in the southern Sentinel Range of the Ellsworth Mountains in Antarctica. The glacier flows along the northwestern side of Petvar Heights and merges with the terminus of the southeast-flowing Thomas Glacier as both glaciers emerge from the range.
Thunder Glacier is located on the west slopes of Mount Baker in the North Cascades of the U.S. state of Washington. The glacier descends to the west on the north side of the Black Buttes.
Davenport Glacier is located in a cirque to the southeast of Boston Peak, North Cascades National Park in the U.S. state of Washington. The glacier is approximately .20 mi (0.32 km) in length resting at between 8,000 and 7,500 ft. The glacier is also northeast of Sahale Mountain and separated from the much larger Boston Glacier to the north by an arête called "Ripsaw Ridge".
Inspiration Glacier is on the east slopes of Eldorado Peak, North Cascades National Park in the U.S. state of Washington. The glacier is approximately 1.5 mi (2.4 km) in length, 2 mi (3.2 km) in width at its terminus and descends from 8,500 to 6,800 ft. Inspiration Glacier lies in a cirque with Eldorado Peak to the west, the arête known as Tepeh Towers to the northwest and Klawatti Peak to the northeast. Inspiration Glacier is connected to the Eldorado Glacier to the south and partially separated by the Tepeh Towers from the McAllister Glacier to the north. Meltwaters from Inspiration Glacier flow into Moraine Lake.
Eldorado Glacier is on the south slopes of Eldorado Peak, North Cascades National Park, in the U.S. state of Washington. The glacier is approximately .85 mi (1.37 km) in length, 1.2 mi (1.9 km) in width at its terminus and descends from 8,400 to 7,000 ft. Eldorado Glacier is connected to Inspiration Glacier on its upper slopes. Glacial melt waters from Eldorado Glacier flow south over Roush Creek Falls, which at 2,000 ft (610 m), is one of the tallest waterfalls in Washington.
Muldrow Glacier, also known as McKinley Glacier, is a large glacier in Denali National Park and Preserve in the U.S. state of Alaska. Native names for the glacier include, Henteel No' Loo' and Henteel No' Loot.
