Gannett Glacier
Gannett Glacier is the largest glacier in the Rocky Mountains within the United States. The glacier is located on the east and north slopes of Gannett Peak, the highest mountain in Wyoming, on the east side of the Continental Divide in the Wind River Range. Gannett is but one of dozens of glaciers located in the Fitzpatrick Wilderness of Shoshone National Forest. As is true with many glaciers around the world, Gannett Glacier is slowly disappearing. Photographic evidence clearly demonstrates that there has been an enormous reduction in the area of the glacier since the 1920s. The area of the glacier was estimated in 1950 to be and was measured in 1999 to be . Measurements taken in 1958 and again in 1983 showed a depth reduction of over 25 years. A general warming pattern and a reduction in moisture is widely believed to be the reason for the glacier retreating. Numerous other glaciers are located in the immediate area including six more that are within the top ten in size within ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gannett Peak
Gannett Peak is the highest mountain peak in the U.S. state of Wyoming at . It lies in the Wind River Range within the Bridger Wilderness of the Bridger-Teton National Forest. Straddling the Continental Divide along the boundary between Fremont and Sublette counties, it has the second greatest topographic prominence in the state (7076') after Cloud Peak (7077'), and is the highest ground for in any direction. Overview Geographically, Gannett Peak is the apex of the entire Central Rockies, the largely continuous chain of mountains occupying the states of Wyoming, Idaho and Montana. Named in 1906 for American geographer Henry Gannett, the peak is also the high point of the Wind River Range. The mountain slopes are located in both Bridger-Teton National Forest and Shoshone National Forest. Gannett is the highest peak within what is better known as the Greater Yellowstone Ecosystem and is the highest peak in the Rocky Mountains outside of Colorado. The Gannett Glacier, whic ...

Fremont County, Wyoming
Fremont County is a county in the U.S. state of Wyoming. As of the 2020 United States Census, the population was 39,234, making it the fifth-most populous county in Wyoming. Its county seat is Lander. The county was founded in 1884 and is named for John C. Frémont, a general, explorer, and politician. It is roughly the size of the state of Vermont. Fremont County comprises the Riverton, WY Micropolitan Statistical Area. History Fremont County was created on March 5, 1884 by the legislature of the Wyoming Territory. The county was created with land ceded by Sweetwater County. In 1890, Big Horn County was carved out of Fremont, Johnson, and Sheridan Counties. Hot Springs County was created in 1911 from parts of Fremont, Big Horn, and Park counties. In 1921, Sublette County was created from parts of Fremont and Lincoln counties, leaving Fremont County's boundary at its present configuration. Fremont County was named for John Charles Frémont, an explorer of the American ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacier
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#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, 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.

Rocky Mountains
The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch in straight-line distance from the northernmost part of western Canada, to New Mexico in the southwestern United States. Depending on differing definitions between Canada and the U.S., its northern terminus is located either in northern British Columbia's Terminal Range south of the Liard River and east of the Trench, or in the northeastern foothills of the Brooks Range/ British Mountains that face the Beaufort Sea coasts between the Canning River and the Firth River across the Alaska-Yukon border. Its southernmost point is near the Albuquerque area adjacent to the Rio Grande rift and north of the Sandia–Manzano Mountain Range. Being the easternmost portion of the North American Cordillera, the Rockies are distinct from the tectonically younger Cascade Range and Sierra Nevada, which both lie farther to its west. The ...

Continental Divide
A continental divide is a drainage divide on a continent such that the drainage basin on one side of the divide feeds into one ocean or sea, and the basin on the other side either feeds into a different ocean or sea, or else is endorheic, not connected to the open sea. Every continent on earth except Antarctica (which has no known significant, definable free-flowing surface rivers) has at least one continental drainage divide; islands, even small ones like Killiniq Island on the Labrador Sea in Canada, may also host part of a continental divide or have their own island-spanning divide. The endpoints of a continental divide may be coastlines of gulfs, seas or oceans, the boundary of an endorheic basin, or another continental divide. One case, the Great Basin Divide, is a closed loop around an endoreic basin. The endpoints where a continental divide meets the coast are not always definite since the exact border between adjacent bodies of water is usually not clearly defined. The I ...

Wind River Range
The Wind River Range (or "Winds" for short) is a mountain range of the Rocky Mountains in western Wyoming in the United States. The range runs roughly NW–SE for approximately . The Continental Divide follows the crest of the range and includes Gannett Peak, which at , is the highest peak in Wyoming; and also Fremont Peak at , the third highest peak in Wyoming. There are more than 40 other named peaks in excess of . With the exception of the Grand Teton in the Teton Range, the next 19 highest peaks in Wyoming after Gannett are also in the Winds. Two large national forests including three wilderness areas encompass most of the mountain range. Shoshone National Forest is on the eastern side of the continental divide while Bridger-Teton National Forest is on the west. Both national forests and the entire mountain range are an integral part of the Greater Yellowstone Ecosystem. Portions of the east side of the range are inside the Wind River Indian Reservation.

Fitzpatrick Wilderness
The Fitzpatrick Wilderness is located in Shoshone National Forest in the U.S. state of Wyoming. The wilderness was originally known as the Glacier Primitive Area, but was redesignated a wilderness in 1976. Overview U.S. Wilderness Areas do not allow motorized or mechanized vehicles, including bicycles. Although camping and fishing are allowed with proper permit, no roads or buildings are constructed and there is also no logging or mining, in compliance with the 1964 Wilderness Act. Wilderness areas within National Forests and Bureau of Land Management areas also allow hunting in season. Hazards Encountering bears is a concern in the Wind River Range. There are other concerns as well, including bugs, wildfires, adverse snow conditions and nighttime cold temperatures. Importantly, there have been notable incidents, including accidental deaths, due to falls from steep cliffs (a misstep could be fatal in this class 4/5 terrain) and due to falling rocks, over the years, inc ...

Shoshone National Forest
Shoshone National Forest ( ) is the first federally protected National Forest in the United States and covers nearly in the state of Wyoming. Originally a part of the Yellowstone Timberland Reserve, the forest is managed by the United States Forest Service and was created by an act of Congress and signed into law by U.S. President Benjamin Harrison in 1891. Shoshone National Forest is one of the first nationally protected land areas anywhere. Native Americans have lived in the region for at least 10,000 years, and when the region was first explored by European adventurers, forestlands were occupied by several different tribes. Never heavily settled or exploited, the forest has retained most of its wildness. Shoshone National Forest is a part of the Greater Yellowstone Ecosystem, a nearly unbroken expanse of federally protected lands encompassing an estimated . The Absaroka and Beartooth Mountains are partly in the northern section of the forest. The Wind River Range is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retreat Of Glaciers Since 1850
The retreat of glaciers since 1850 affects the availability of fresh water for irrigation and domestic use, mountain recreation, animals and plants that depend on glacier-melt, and, in the longer term, the level of the oceans. Deglaciation occurs naturally at the end of ice ages, but glaciologists find the current glacier retreat is accelerated by the measured increase of atmospheric greenhouse gases—an effect of climate change. Mid-latitude mountain ranges such as the Himalayas, Rockies, Alps, Cascades, Southern Alps, and the southern Andes, as well as isolated tropical summits such as Mount Kilimanjaro in Africa, are showing some of the largest proportionate glacial losses. Excluding peripheral glaciers of ice sheets, the total cumulated global glacial losses over the 26 year period from 1993–2018 were likely 5500 gigatons, or 210 gigatons per yr.Fox-Kemper, B., H.T.

Dinwoody Glacier
Dinwoody Glacier is located in Shoshone National Forest, in the U.S. state of Wyoming on the east side of the Continental Divide in the Wind River Range. Completely within the Fitzpatrick Wilderness, Dinwoody Glacier is one of the largest glaciers in the American Rocky Mountains, and as of 1989 was ranked fourth in area. In a 1989 study which examined repeat photography and stream flow analysis, Dinwoody Glacier was determined to have retreated rapidly between 1958 and 1983, though most of the reduction has been in the thickness of the glacier rather than its surface area. In the same 25-year period, the glacier lost an average of in thickness. Radar mapping of 72 locations on the glacier resulted in an average thickness of and a maximum measured depth of . The 1989 study was commenced to examine the impact on water supplies to streams and rivers from glacier retreat of both Dinwoody and Gannett Glaciers.

Wind River (Wyoming)
The Wind River is the name applied to the upper reaches of the Bighorn River in Wyoming in the United States. The Wind River is long. The two rivers are sometimes referred to as the Wind/Bighorn. Course Its headwaters are at Wind River Lake in the Rocky Mountains, near the summit of Togwotee Pass (pronounced TOH-guh-tee) and gathers water from several forks along the northeast side of the Wind River Range in west central Wyoming. It flows southeastward, across the Wind River Basin and the Wind River Indian Reservation and joins the Little Wind River near Riverton. Up stream from this confluence, it is known locally as the Big Wind River. It flows northward, through a gap in the Owl Creek Mountains, where the name of the river becomes the Bighorn River. In the Owl Creek Mountains, it is dammed to form Boysen Reservoir. The Wind River officially becomes the Bighorn River at the Wedding of the Waters, on the north side of the Wind River Canyon.
