Davidson Glacier
The Davidson Glacier is a large glacier, valley glacier near Haines, Alaska, Haines, Alaska that finds its source in the Chilkat Range. History The Davidson Glacier was named in 1867 for George Davidson (geographer), George Davidson. Its Indian name is Ssitkaje. It was recounted by John Muir in his famous travels in and around Glacier Bay in 1879. The glacier was, at that time, a glacier that nearly reached tidewater.(Wilderness Essays, The Alaska Trip (pg 60) John Muir). It has since receded into the mountains, becoming a valley glacier, and created its very own glacial lake in the glacier's moraine (similar to the Mendenhall Glacier and Mendenhall Lake, lake) about one mile inland from the Chilkat Inlet. Current status Currently, the Davidson Glacier serves as a tourist attraction for Haines and Skagway.

Mendenhall Glacier
Mendenhall Glacier () is a glacier about long located in Mendenhall Valley, about from downtown Juneau in the southeast area of the U.S. state of Alaska. The glacier and surrounding landscape is protected as part of the Mendenhall Glacier Recreation Area, a federally designated unit of the Tongass National Forest. The Juneau Icefield Research Program has monitored the outlet glaciers of the Juneau Icefield since 1942, including Mendenhall Glacier. The glacier has also retreated since 1929, when Mendenhall Lake was created, and over since 1500. The end of the glacier currently has a negative glacier mass balance and will continue to retreat in the foreseeable future. Given that average yearly temperatures are currently increasing, and the outlook is for this trend to continue, it is actually possible that the glacier might experience a period of stabilization or slight advance during its retreating march. This is because increasing amounts of warm, moist air will be car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glaciers Of Alaska
A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land“Glacier, N., Pronunciation.” Oxford English Dictionary, Oxford UP, June 2024, https://doi.org/10.1093/OED/7553486115. Accessed 25 Jan. 2025. and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every contin ...

Mount Rifenburgh
The Holland Range () is a rugged coastal mountain range in the Ross Dependency, Antarctica, on the west coast of the Ross Ice Shelf. It is about long. Location The Holland Range lies just west of the Ross Ice Shelf and extends from Robb Glacier in the northeast to Lennox-King Glacier in the south. To the north of the range is the "island" that holds Cape Lyttelton. To the west, on the west side of Robb Glacier, is the Queen Elizabeth Range. To the south, across the Lennox-King Glacier, is the Queen Alexandra Range. The range was named by the Ross Sea Committee for Sir Sidney Holland, who as Prime Minister of New Zealand supported that nation's participation in the Commonwealth Trans-Antarctic Expedition (1956–58). Glaciers The Robb Glacier flows from Clarkson Peak north along the east side of Softbed Ridges to the Ross Ice Shelf at Cape Goldie. It flows between the Queen Elizabeth Range to the west and the Holland Range to the east. To the north of Softbed Ridges it co ...

List Of Glaciers
A glacier ( ) or () is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. Because glacial mass is affected by long-term climate changes, e.g., precipitation, mean temperature, and cloud cover, glacial mass changes are considered among the most sensitive indicators of climate change. There are about 198,000 to 200,000 glaciers in the world.

Glacier Bay
Glacier Bay Basin in southeastern Alaska, in the United States, encompasses the Glacier Bay and surrounding mountains and glaciers, which was first proclaimed a U.S. National Monument on February 25, 1925, and which was later, on December 2, 1980, enlarged and designated as the Glacier Bay National Park and Preserve under the Alaska National Interest Lands Conservation Act, covering an area of . In 1986, UNESCO declared an area of within a World Biosphere Reserve. This is the largest UNESCO protected biosphere in the world. In 1992, UNESCO included this area as a part of a World Heritage site, extending over an area of which also included the Wrangell-St. Elias National Park, Kluane National Park (Canada) and Tatshenshini-Alsek Park (Canada). Part of the National Park is also designated a Wilderness area covering . Current glaciers cover an area and accounts for 27% of the Park area. Up until the early 1700s the area was a large single glacier of solid ice. It has since retre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Muir
John Muir ( ; April 21, 1838December 24, 1914), also known as "John of the Mountains" and "Father of the national park, National Parks", was a Scottish-born American naturalist, author, environmental philosopher, botanist, zoologist, glaciologist, and early advocate for the preservation of wilderness in the United States. His books, letters and essays describing his adventures in nature, especially in the Sierra Nevada, have been read by millions. His activism helped to preserve the Yosemite Valley and Sequoia National Park, and his example has served as an inspiration for the preservation of many other wilderness areas. The Sierra Club, which he co-founded, is a prominent American conservation organization. In his later life, Muir devoted most of his time to his wife and the preservation of the Western forests. As part of the campaign to make Yosemite a national park, Muir published two landmark articles on wilderness preservation in ''The Century Magazine'', "The Treasures of ...

George Davidson (geographer)
George Davidson (May 9, 1825 – December 1, 1911) was a geodesist, astronomer, geographer, surveyor and engineer in the United States. Biography Born on May 9, 1825, in England, he went to the U.S. in 1832 with his parents, who settled in Pennsylvania. He graduated at the Central High School in Philadelphia in 1845, standing first in his class. While a student, he had shown interest in scientific work, and had assisted Alexander D. Bache in his observations of the magnetic elements at Girard College. Upon his graduation in 1845, he began his career as clerk to Bache who was superintendent of the United States Coast Survey. From 1846 to 1850, Davidson was occupied in geodesy, and in astronomy, serving in the different states on the east coast of the United States. In 1850, Bache sent him to California at the rank of Coast Survey assistant. For the next decade, Davidson engaged in field work to determine the exact latitude and longitude of prominent capes, bays, etc., and of the m ...
