Grebe Lake
Grebe Lake is a backcountry lake in Yellowstone National Park most noted for its population of Arctic grayling. Grebe Lake comprises the headwaters of the Gibbon River. Grebe Lake is located approximately north of the Norris-Canyon section of the Grand Loop Road. The trail to the lake passes through mostly level Lodgepole Pine forest and open meadows. The lake was named by J.P. Iddings, a geologist with the Arnold Hague geologic surveys. There are four backcountry campsites located on the lake. Arctic grayling In 1921, U.S. Fish Commission personnel stocked Grebe Lake, at that time fishless, with the Montana strain ''Thymallus arcticus montanus'' of a lacustrine form of Arctic Grayling. The original stocks came from Georgetown Lake near Anaconda, Montana. The fluvial form of Arctic Grayling was native to the Madison and Gibbon Rivers below Gibbon Falls. In an effort to re-establish grayling in western states, over 72 million grayling eggs were harvested from Grebe Lake be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellowstone National Park
Yellowstone National Park is an American national park located in the western United States, largely in the northwest corner of Wyoming Wyoming () is a state in the Mountain West subregion of the Western United States. It is bordered by Montana to the north and northwest, South Dakota and Nebraska to the east, Idaho to the west, Utah to the southwest, and Colorado to the sou ... and extending into Montana and Idaho. It was established by the 42nd United States Congress, 42nd U.S. Congress with the Yellowstone National Park Protection Act and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world. The park is known for List of animals of Yellowstone, its wildlife and Geothermal areas of Yellowstone, its many geothermal features, especially the Old Faithful geyser, one of its most popular. While it represents many types of biomes, the subalpi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madison River
The Madison River is a headwater tributary of the Missouri River, approximately 183 miles (295 km) long, in Wyoming and Montana. Its confluence with the Jefferson and Gallatin rivers near Three Forks, Montana forms the Missouri River. The Madison rises in Teton County in northwestern Wyoming at the confluence of the Firehole and Gibbon rivers, a location in Yellowstone National Park called ''Madison Junction''. It first flows west, then north through the mountains of southwestern Montana to join the Jefferson and the Gallatin rivers at Three Forks. The Missouri River Headwaters State Park is located on the Madison at Three Forks. In its upper reaches in Gallatin County, Montana, the Hebgen Dam forms Hebgen Lake. In its middle reaches in Madison County, Montana, the Madison Dam forms Ennis Lake and provides hydroelectric power. In 1959, the 1959 Hebgen Lake earthquake formed Quake Lake just downstream from Hebgen Dam. Downstream from Ennis, the Madison flows through ...

Lakes Of Wyoming
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishes Of Yellowstone National Park
The fish of Yellowstone National Park, in Idaho, Montana and Wyoming (U.S.), include 13 native fish species and six introduced or non-native species. Angling for trout has been a pastime in the park since its creation and trout species dominate the fish inhabiting the park. When Yellowstone National Park was created in 1872, 40% of the park's waters were barren of fish, including most alpine lakes and rivers above major waterfalls. Only 17 of 150 lakes held fish. In 1889 the U.S. Bureau of Fisheries began a 60-year program of stocking and hatchery operations that significantly altered the ranges of native and non-native species within the park. By 1955, all stocking and hatchery operations in the park had been stopped. Several introduced species never established viable populations, and at least one introduced species was successfully eradicated from the park. Native species The following fish are native to the park, although their original ranges may have been severely reduce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angling In Yellowstone National Park
Angling in Yellowstone National Park is a major reason many visitors come to the park each year and since it was created in 1872, the park has drawn anglers from around the world to fish its waters. In 2006, over 50,000 park fishing permits were issued to visitors. The park contains hundreds of miles of accessible, high-quality trout rivers containing wild trout populations—over 200 creeks, streams and rivers are fishable. There are 45 fishable lakes and several large lakes are easily accessible to visitors. Additionally, the park's remote sections provide anglers ample opportunity to visit rivers, streams, creeks and lakes that receive little angling pressure. With the exception of one specially designated drainage, all the park's waters are restricted to artificial lures and fly fishing. The Madison, Firehole and a section of the Gibbon rivers are restricted to fly fishing only. Anglers visiting the park to fish will encounter westslope cutthroat, Yellowstone cutthroat ...

Float Tube
A float tube, also known as a belly boat or kick boat, is a small, lightweight inflatable fishing craft which anglers use to fish from. They were originally doughnut-shaped boats with an underwater seat in the "hole." Modern designs include a V-shape with pontoons on either side and the seat raised above the water allowing the legs of the angler to be the only part of the body to be submerged. Float tubes are used for many aspects of fishing, such as flyfishing for trout or lure fishing for largemouth bass, and enable the angler to fish areas otherwise not fishable from the bank. Float tubes are either "U", "V"-shaped, or circular. A standard float tube consists of an inflated bladder inside a sewn cover providing the seat, reserve air compartments, and tackle storage pockets. Many float tube anglers customize their crafts with rod holders, lights, and electronic fish finders. Details The angler generally wears stocking foot chest waders and scuba diving flippers, so the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluvial Processes
In geography and geology, fluvial processes are associated with rivers and streams and the deposits and landforms created by them. When the stream or rivers are associated with glaciers, ice sheets, or ice caps, the term glaciofluvial or fluvioglacial is used. Fluvial processes Fluvial processes include the motion of sediment and erosion or deposition on the river bed. The movement of water across the stream bed exerts a shear stress directly onto the bed. If the cohesive strength of the substrate is lower than the shear exerted, or the bed is composed of loose sediment which can be mobilized by such stresses, then the bed will be lowered purely by clearwater flow. In addition, if the river carries significant quantities of sediment, this material can act as tools to enhance wear of the bed ( abrasion). At the same time the fragments themselves are ground down, becoming smaller and more rounded (attrition). Sediment in rivers is transported as either bedload (the coarser frag ...

Westslope Cutthroat Trout
The westslope cutthroat trout (''Oncorhynchus clarkii lewisi''), also known as the black-spotted trout, common cutthroat trout and red-throated trout is a subspecies of the cutthroat trout (''Oncorhynchus clarkii'') and is a freshwater fish in the salmon family (biology), family (family Salmonidae) of order (biology), order Salmoniformes. The cutthroat is the Montana state fish.1-1-507. State fish Montana Code, accessed 23 April 2009. This subspecies is a ''species of concern'' in its Montana and British Columbia ranges and is considered ''threatened'' in its native range in Alberta. Taxonomy The scientific name of the westslope cutthroat trout is ''Oncorhynchus clarkii lewisi''. The subspecies was first described in the journals of explorer William Clark from specimens obtained during the Lewis and Clark E ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotenone
Rotenone is an odorless, colorless, crystalline isoflavone used as a broad-spectrum insecticide, piscicide, and pesticide. It occurs naturally in the seeds and stems of several plants, such as the jicama vine plant, and the roots of several members of Fabaceae. It was the first described member of the family of chemical compounds known as rotenoids. Discovery The earliest record of the now-known rotenone-containing plants used for killing leaf-eating caterpillars was in 1848, and for centuries, the same plants were used to poison fish. The active chemical component was first isolated in 1895 by a French botanist, Emmanuel Geoffroy, who called it ''nicouline'', from a specimen of ''Robinia nicou'', now called ''Lonchocarpus nicou'', while traveling in French Guiana. He wrote about this research in his thesis, published in 1895 after his death from a parasitic disease. In 1902 Kazuo Nagai, Japanese chemical engineer of the Government-General of Taiwan, isolated a pure crystalline ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rainbow Trout
The rainbow trout (''Oncorhynchus mykiss'') is a species of trout native to cold-water tributaries of the Pacific Ocean in Asia and North America. The steelhead (sometimes called "steelhead trout") is an anadromous (sea-run) form of the coastal rainbow trout or Columbia River redband trout that usually returns to freshwater to spawn after living two to three years in the ocean. Freshwater forms that have been introduced into the Great Lakes and migrate into tributaries to spawn are also called steelhead. Adult freshwater stream rainbow trout average between , while lake-dwelling and anadromous forms may reach . Coloration varies widely based on subspecies, forms, and habitat. Adult fish are distinguished by a broad reddish stripe along the lateral line, from gills to the tail, which is most vivid in breeding males. Wild-caught and hatchery-reared forms of the species have been transplanted and introduced for food or sport in at least 45 countries and every continent e ...

Gibbon Falls
Gibbon Falls is a waterfall on the Gibbon River in northwestern Yellowstone National Park in the United States. Gibbon Falls has a drop of approximately . The falls are located roadside, upstream from the confluence of the Gibbon and Firehole Rivers at Madison Junction on the Grand Loop Road. History The falls were first described by William Henry Jackson during the second Hayden geological survey of 1872. There is no historical record as to how they got their name, but by the mid-1880s, they were routinely referred to as ''Gibbon Falls'' in both government and commercial accounts of the park. In 1883, in his ''The Yellowstone National Park-A Manual for Tourists'', Henry J. Winser described the falls: In 1895, Hiram M. Chittenden described Gibbon Falls in his ''Yellowstone National Park-Historical and Descriptive.'' In 1895, the road was on the opposite side of the river from where it runs today.
