Davidson Glacier
The Davidson Glacier is a large valley glacier near Haines, Alaska that finds its source in the Chilkat Range. History The Davidson Glacier was named in 1867 for 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 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 (in Tlingit language “Sít”) 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glaciers Of Alaska
A glacier (; ) is a persistent body of dense ice that is constantly moving 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 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 continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between latitudes 35°N and 35°S, glaciers occur only in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. Glaciers by continent Africa Africa, specifically East Africa, has contained glacial regions, possibly as far back as the last glacier maximum 10 to 15 thousand years ago. Seasonal snow does exist on the highest peaks of East Africa as well as in the Drakensberg Range of South Africa, the Stormberg Mountains, and the Atlas Mountains in Morocco. Currently, ...

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 3,283,000 acres (1,329,000 ha). In 1986, UNESCO declared an area of 57,000 acres (23,000 ha) 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 24,300,000-acre (98,000 km2) 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 2,658,000 acres (1,076,000 ha). Current glaciers cover an area 1,375 square miles ...

John Muir
John Muir ( ; April 21, 1838December 24, 1914), also known as "John of the Mountains" and "Father of the National Parks", was an influential Scottish-American naturalist, author, environmental philosopher, botanist, zoologist, glaciologist, and early advocate for the preservation of wilderness in the United States of America. His letters, essays, and books 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 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 the ...

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 geodetic field work, and in astronomy, serving in the different states on the east coast of the United States. In 1850, he went to California under the auspices of the Coast Survey, and was for several years engaged in the determination of the latitude and longitude of prominent capes, bays, etc., and of the magneti ...
