Gannett Glacier is the largest glacier in the Rocky Mountains within the United States. Square Kilometre ( US spelling square kilometer) symbol km2, is a decimal multiple of the SI unit of The acre is a unit of Area in a number of different systems including the imperial and U "Glacial" and "Glaciation" redirect here For the geological periods see Glacial period. Mountain peaks of the Rocky Mountains The Rocky Mountains, often called the Rockies, are a Mountain range in western North America. The United States of America —commonly referred to as the 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 Peak is the highest peak in the US state of Wyoming and straddles the boundary between Fremont and Sublette Counties The State of Wyoming ( is a sparsely populated state in the western region of the United States. A continental divide is a line of elevated Terrain which forms a border between two watersheds such that Water falling on one side of the line eventually The Wind River Range (or "Winds" for short is a Mountain range of the Rocky Mountains in western Wyoming in the United States. Gannett is but one of dozens of glaciers located in the Fitzpatrick Wilderness of Shoshone National Forest. The Fitzpatrick Wilderness is located in Shoshone National Forest in the U Shoshone National Forest () is the first federally protected National Forest in the United States and covers nearly 2 [1]
As is true with most 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. Photography (fә'tɒgrәfi or fә'tɑːgrәfi (from Greek φωτο and γραφία is the process and Art of recording pictures by means of capturing The area of the glacier was estimated in 1950 to be 4. 6 square kilometres (1,137 acres) and was measured in 1999 to be 3. 63 square kilometres (897 acres). Square Kilometre ( US spelling square kilometer) symbol km2, is a decimal multiple of the SI unit of The acre is a unit of Area in a number of different systems including the imperial and U Measurements taken in 1958 and again in 1983 showed a depth reduction of 18. 6 metres (61 ft) over 25 years. The metre or meter is a unit of Length. It is the basic unit of Length in the Metric system and in the International A foot (plural feet or foot; symbol or abbreviation ft or sometimes &prime – the prime symbol) is a non-SI unit [2] A general warming pattern and a reduction in moisture is widely believed to be the reason for the glacier retreating. whitechuck glacier 2006jpg|right|thumb|320px|The same view as seen in 2006 where this branch of glacier retreated 1 [3] Numerous other glaciers are located in the immediate area including six more that are within the top ten in size within the Rocky Mountains of the U. S. [2]
In a 1989 study, both Gannett and Dinwoody glaciers were researched to determine the amount of melt water they supplied to streams. Dinwoody Glacier is located in Shoshone National Forest, in the U Both glaciers supply melt water which flows into Dinwoody Creek, which in turn flows into the Wind River. The melt water was found to have contributed increasingly lower amounts to the total water supplied to Dinwoody Creek. This has been attributed to the glaciers thinning and retreating, especially since 1950, when Gannett Glacier was measured to be almost 20 percent larger than in 1999. [4] The impact on reduced stream flow from Gannett Glacier due to glacial retreat affects more than just the amount of water available for the local ecosystem and downstream agricultural and ranching interests. Cool water fish species including the brook trout, cutthroat trout and rainbow trout could see a loss of habitat and spawning areas as water temperatures rise due to less glacier ice melt. The brook trout, Salvelinus fontinalis, (sometimes called the eastern brook trout, Adirondack coaster lake trout) is a Species of Fish The cutthroat trout ( Oncorhynchus clarki) is a Species of Freshwater Fish in the salmon family of order The rainbow trout ( Oncorhynchus mykiss) is a species of Salmonid native to tributaries of the Pacific Ocean in Asia and North America [3]
