Lower Fremont Glacier
Lower Fremont Glacier is east of the Continental Divide in the northern Wind River Range in the U.S. state of Wyoming. The glacier is in the Fitzpatrick Wilderness of Shoshone National Forest, and is among the largest grouping of glaciers in the American Rocky Mountains. Lower Fremont Glacier flows to the southeast and the rapid retreat of this glacier has left behind lateral moraines and a proglacial lake. Lower Fremont Glacier is separated from the Bull Lake Glacier by a moraine and from the Upper Fremont Glacier by cliffs.

Continental Divide Of The Americas
The Continental Divide of the Americas (also known as the Great Divide, the Western Divide or simply the Continental Divide; ) is the principal, and largely mountainous, hydrological divide of the Americas. The Continental Divide extends from the Bering Strait to the Strait of Magellan, and separates the watersheds that drain into the Pacific Ocean from those river systems that drain into the Atlantic and (in northern North America) Arctic oceans (including those that drain into the Gulf of Mexico, the Caribbean Sea and Hudson Bay). Although there are many other hydrological divides in the Americas, the Continental Divide is by far the most prominent of these because it tends to follow a line of high peaks along the main ranges of the Rocky Mountains and Andes, at a generally much higher elevation than the other hydrological divisions. Geography Beginning at the westernmost point of the Americas’ mainland (Cape Prince of Wales, just south of the Arctic Circle), the Conti ...

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] |
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 ...

Moraine
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Provenà ...

Proglacial Lake
In geology, a proglacial lake is a lake formed either by the damming action of a moraine during the retreat of a melting glacier, a glacial ice dam, or by meltwater trapped against an ice sheet due to isostatic depression of the crust around the ice. At the end of the last ice age about 10,000 years ago, large proglacial lakes were a widespread feature in the northern hemisphere. Moraine-dammed The receding glaciers of the tropical Andes have formed a number of proglacial lakes, especially in the Cordillera Blanca of Peru, where 70% of all tropical glaciers are. Several such lakes have formed rapidly during the 20th century. These lakes may burst, creating a hazard for zones below. Many natural dams (usually moraines) containing the lake water have been reinforced with safety dams. Some 34 such dams have been built in the Cordillera Blanca to contain proglacial lakes. Several proglacial lakes have also formed in recent decades at the end of glaciers on the eastern side of Ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bull Lake Glacier
Bull Lake Glacier is located immediately east of the Continental Divide in the northern Wind River Range in the U.S. state of Wyoming. The glacier is in the Fitzpatrick Wilderness of Shoshone National Forest, and is among the largest grouping of glaciers in the American Rocky Mountains. Bull Lake Glacier flows to the east and starts below the summit of Jackson Peak. It is adjacent to Lower Fremont Glacier though the two are separated by a moraine.

Upper Fremont Glacier
Upper Fremont Glacier is in the Fitzpatrick Wilderness of Shoshone National Forest in the U.S. state of Wyoming. This Wind River Range alpine glacier is associated with the largest grouping of glaciers in the U.S. Rocky Mountains and lies on the north slope of Fremont Peak, the third tallest mountain in Wyoming. Upper Fremont Glacier is at an average altitude of and is one of the highest altitude glaciers in the American Rockies. Ice core samples were taken from Upper Fremont Glacier in 1990-1991. These ice cores were analyzed for climatic changes as well as alterations of atmospheric chemicals. In 1998 an unbroken ice core sample of was taken from the glacier and subsequent analysis of the ice showed an abrupt change in the oxygen isotope ratio oxygen-18 to oxygen-16 in conjunction with what is widely regarded as the end of the Little Ice Age, a period of cooler global temperatures between the years 1550 and 1850. A linkage was established with a similar ice core study which h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
