Unicorn Glacier is in Mount Rainier National Park in the U.S. state of Washington, on the northwest slope of Unicorn Peak. [2] Unicorn Glacier is a semi-permanent snowfield but is listed on older United States Geological Survey maps.
The Usarp Mountains are a major Antarctic mountain range, lying west of the Rennick Glacier and trending north to south for about 190 kilometres (118 mi). The feature is bounded to the north by Pryor Glacier and the Wilson Hills.
Mount Wrangell, in Ahtna K’ełt’aeni or K’ełedi when erupting, is a massive shield volcano located in Wrangell-St. Elias National Park and Preserve in southeastern Alaska, United States. The shield rises over 12,000 feet (3,700 m) above the Copper River to its southwest. Its volume is over 220 cubic miles (920 km3), making it more than twice as massive as Mount Shasta in California, the largest stratovolcano by volume in the Cascades. It is part of the Wrangell Volcanic Field, which extends for more than 250 kilometers (160 mi) across Southcentral Alaska into the Yukon Territory in Canada, and has an eruptive history spanning the time from Pleistocene to Holocene.
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.
Jackson Glacier is approximately the seventh largest of the remaining 25 glaciers in Glacier National Park located in the US state of Montana. A part of the largest grouping of glaciers in the park, Jackson Glacier rests on the north side of Mount Jackson. The glacier was most recently measured in 2005 at 250 acres (1.0 km2), yet when first documented in 1850, the glacier also included the now separate Blackfoot Glacier and together, they covered 1,875 acres (7.59 km2). Between 1966 and 2005, Jackson Glacier lost almost a third of its acreage. When the two mountains were united prior to their separation sometime before 1929, they were known simply as Blackfoot Glacier.
Mount Bird is a 1,765 m (5,791 ft) high shield volcano standing about 7 miles (11 km) south of Cape Bird, the northern extremity of Ross Island. It was mapped by the British National Antarctic Expedition, 1901–04, under Robert Falcon Scott, and apparently named by them after Cape Bird. Endeavour Piedmont Glacier lies on its slopes.
Rippon Glacier is a small glacier located in Kemp Land, East Antarctica. It is close east of Seaton Glacier, flowing southward into Edward VIII Ice Shelf.
Logan Glacier is in Glacier National Park in the U.S. state of Montana. The glacier is situated in a cirque to the northeast of Mount Logan. Just east of the Continental Divide, Logan Glacier is northwest of Red Eagle Glacier. Estimated in 2005 to cover an area of 75 acres (0.30 km2), Logan Glacier covered almost 125 acres (0.51 km2) in 1966, a reduction in area of 40 percent in about 40 years. Comparing images of the glacier taken in 1914 with those from 2009, indicates that the glacier has experienced extensive retreat.
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.
Gildea Glacier is a glacier 10 kilometres (6 mi) long and 5 kilometres (3 mi) wide flowing southwestward from Craddock Massif between Mount Slaughter and Mount Atkinson into Nimitz Glacier, in the Sentinel Range of the Ellsworth Mountains, Antarctica. The upper portion of the glacier also receives ice from Hammer Col and southern Vinson Massif.
Harrison Glacier is a glacier located in the US state of Montana in Glacier National Park. Situated on a southeast‐facing ridge immediately south of Mount Jackson, it is the largest remaining glacier in Glacier National Park, estimated in 2005 to have an area of 466 acres (1.89 km2). Though many experts have stated that all the glaciers in Glacier National Park may disappear by the year 2030, Harrison Glacier lost only 9 percent of its surface area in the 40-year period between 1966 and 2005 and will likely still exist well beyond 2030. Compared to many of the vanishing glaciers in Glacier National Park, Harrison Glacier's accumulation zone is at a much higher altitude, which has allowed it to maintain some equilibrium in its glacier mass balance. Comparisons of images of the glacier taken in 1913 with images from 2009 indicate that the glacier has experienced thinning and retreat.
The Batterbee Mountains are a group of prominent mountains rising to 2,200 metres (7,200 ft), which forms part of the dissected edge of Dyer Plateau overlooking George VI Sound, on the west coast of Palmer Land. First seen and photographed from the air by Lincoln Ellsworth on 23 November 1935, they were charted from the ground in October 1936 by the British Graham Land Expedition (BGLE) under John Rymill, and named after Sir Harry Batterbee (1880–1976), Assistant Under-Secretary of State, Dominions Office, 1930–38, and Chairman of the Polar Committee in 1934, who gave help to the expedition.
Herbst Glacier is located in the US state of Montana in Glacier National Park. The glacier is northeast of Mount Custer and lies above Lake Nooney at an elevation between 7,000 ft (2,100 m) and 8,000 ft (2,400 m) above sea level. Immediately east of the Continental Divide, the glacier covers an area of approximately 13 acres (5.3 ha) and does not meet the threshold of 25 acres (10 ha) often cited as being the minimum size to qualify as an active glacier. Between 1966 and 2005, the glacier lost almost 70 percent of its acreage.
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.
Guerrero Glacier is a glacier about 7 nautical miles (13 km) long in Doyran Heights, draining from the southeast slopes of Mount Havener southwest of Beloslav Peak to the south side of Taylor Spur, in the southeast part of the Sentinel Range, Ellsworth Mountains, Antarctica. It was first 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 John F. Guerrero, a meteorologist at South Pole Station in 1957.
Hale Glacier is a glacier about 6 nautical miles (11 km) long, located just east of Mount Simpson on Thurston Island, Antarctica, and flowing southwest to the Abbot Ice Shelf in Peacock Sound. It was delineated from air photos taken by U.S. Navy Squadron VX-6 in January 1960, and was named by the Advisory Committee on Antarctic Names (US-ACAN) for Lieutenant Bill J. Hale, U.S. Navy, a helicopter pilot aboard USS Burton Island who made exploratory flights to Thurston Island in February 1960.
Hansen Glacier is a tributary glacier 10 nautical miles long, flowing northeast from Mount Tuck between Veregava Ridge and Doyran Heights to join Dater Glacier west of Dickey Peak, in the Sentinel Range of the Ellsworth Mountains in Antarctica.
Hough Glacier is a glacier in central Doyran Heights in the Sentinel Range of Ellsworth Mountains, Antarctica, rising just south of Mount Tuck and flowing east-southeast for 10 nautical miles between Guerrero Glacier and Remington Glacier. It was first 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 William S. Hough, who made ionosphere studies at South Pole Station in 1957.
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.
Hooker Glacier is located in Shoshone National Forest, in the U.S. state of Wyoming, .25 miles (0.40 km) WNW of Mount Hooker. The glacier descends from 11,600 to 11,200 ft.
Lander Glacier is located in the Wind River Indian Reservation, in the U.S. state of Wyoming, .25 miles (0.40 km) WSW of Mount Lander. Lander Glacier consists of three distinct ice bodies along the north and west slopes of Mount Lander, the largest descending from the west slope, from 12,000 to 11,200 ft, immediately east of the Continental Divide.
