Hebgen Lake
Hebgen Lake is a reservoir created by the Hebgen Dam, located in Gallatin County in southwest Montana. It is well known for the 1959 Hebgen Lake earthquake (magnitude 7.1 to 7.5) which occurred nearby on August 17, 1959, forming Quake Lake, which is located immediately downstream. Geography Hebgen Lake is located in southwest Montana. It lies approximately northwest of West Yellowstone and southwest of Ennis. It is approximately long and wide, covering . At its deepest it is , with a volume of . In addition to the Madison River, which flows through the reservoir, the tributaries include the South Fork Madison River, which feeds the southeastern Madison Arm, as well as Duck Creek, Grayling Creek and Red Canyon Creek, which flow into the eastern Grayling Arm. To the west, opposite the Grayling Arm, Watkins Creek flows into the main part of the reservoir.

Gallatin County, Montana
Gallatin County is a county located in the U.S. state of Montana. With its county seat in Bozeman, it is the second-most populous county in Montana, with a population of 118,960 in the 2020 Census. The county's prominent geographical features are the Bridger mountains in the north, and the Gallatin mountains and Gallatin River in the south, named by Meriwether Lewis in 1805 for Albert Gallatin, the United States Treasury Secretary who formulated the Lewis and Clark Expedition. At the southern end of the county, West Yellowstone's entrance into Yellowstone National Park accounts for around half of all park visitors. Big Sky Resort, one of the largest ski resorts in the United States, lies in Gallatin and neighboring Madison counties, midway between Bozeman and West Yellowstone. History During the territorial era, a small patch of land known as " Lost Dakota" existed as a remote exclave of Dakota Territory until it was transferred to Gallatin County, Montana Territory ...

Cyanobacteria
Cyanobacteria ( ) are a group of autotrophic gram-negative bacteria that can obtain biological energy via oxygenic photosynthesis. The name "cyanobacteria" () refers to their bluish green (cyan) color, which forms the basis of cyanobacteria's informal common name, blue-green algae. Cyanobacteria are probably the most numerous taxon to have ever existed on Earth and the first organisms known to have produced oxygen, having appeared in the middle Archean eon and apparently originated in a freshwater or terrestrial environment. Their photopigments can absorb the red- and blue-spectrum frequencies of sunlight (thus reflecting a greenish color) to split water molecules into hydrogen ions and oxygen. The hydrogen ions are used to react with carbon dioxide to produce complex organic compounds such as carbohydrates (a process known as carbon fixation), and the oxygen is released as a byproduct. By continuously producing and releasing oxygen over billions of years, cyanobacte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reservoirs In Montana
A reservoir (; ) is an enlarged lake behind a dam, usually built to store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley and rely on the natural topography to provide most of the basin of the reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by creeks, rivers or rainwater that runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive diverted water from a nearby stream or aqueduct or pipeline water from other on-stream reservoirs. Dams are typically loc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yellowstone Caldera
The Yellowstone Caldera, also known as the Yellowstone Plateau Volcanic Field, is a Quaternary caldera complex and volcanic plateau spanning parts of Wyoming, Idaho, and Montana. It is driven by the Yellowstone hotspot and is largely within Yellowstone National Park. The field comprises four overlapping calderas, multiple lava domes, resurgent domes, crater lakes, and numerous bimodal lavas and tuffs of basaltic and rhyolitic composition, originally covering about . Volcanism began 2.15 million years ago and proceeded through three major volcanic cycles. Each cycle involved a large ignimbrite eruption, continental-scale ash-fall, and caldera collapse, preceded and followed by smaller lava flows and tuffs. The first and also the largest cycle was the Huckleberry Ridge Tuff eruption about 2.08 million years ago, which formed the Island Park Caldera. The most recent supereruption, about 0.63 million years ago, produced the Lava Creek Tuff and created the present Yellowsto ...

Firehole Ranch
Firehole Ranch is a private 640-acre guest ranch located on Hebgen Lake in Gallatin County, Montana. Owned and operated by Lynda Caine since 1999, Firehole Ranch was founded in the late 1890s as Watkins Creek Ranch by George S. Watkins. Originally much larger, Watkins Creek Ranch sold much of its land to the Madison Power and Light Company in 1904 to make way for the Hebgen Lake Dam. Much of Watkins’ cattle were sold to Yellowstone National Park while the remaining land was converted into a dude ranch. Firehole Ranch was entered into the National Register of Historic Places The National Register of Historic Places (NRHP) is the Federal government of the United States, United States federal government's official United States National Register of Historic Places listings, list of sites, buildings, structures, Hist ... under the name Watkins Creek Ranch on December 27, 2006.

Utah Chub
The Utah chub (''Gila atraria'') is a freshwater fish of the family Leuciscidae native to the western United States, where it is abundant in the upper Snake River basin and the Bonneville basin. The species name ''atraria'' references the latin word ''ater'', which means black. The name is likely a reference to the dark coloration of the fins and body. Description The dorsal fin of the Utah chub contains nine rays and is located directly over the pelvic fins. Coloration of this species is variable; the dorsal side is generally olive-green ranging to nearly black, and sometimes with a bluish shade, while the sides are silvery, brassy, or golden. Males have somewhat more of a golden look, especially during spawning season, often including a narrow golden stripe along the upper side. Fin colors include olive-green, yellow, and golden shades. A maximum total length of and weight of was reported from Bear Lake, but sizes of are more typical in many locations. Age estimates ...

Mountain Whitefish
The mountain whitefish (''Prosopium williamsoni'') is one of the most widely distributed salmonid fish of western North America. It is found from the Mackenzie River drainage in Northwest Territories, Canada through western Canada and the northwestern USA in the Pacific, Hudson Bay and upper Missouri River basins to the Truckee River drainage in Nevada and Sevier River drainage in Utah. Description The body shape is superficially similar to the cyprinids, although it is distinguished by having both the adipose fin and axillary process of salmonids. The body is slender and nearly cylindrical in cross section, generally silver with a dusky olive-green shade dorsally. The scales possess pigmented borders, which are especially defined on the posterior end. Mountain whitefish possess a forked homocercal tail. The short head has a small mouth underneath the snout. The short dorsal fin has 12–13 rays, with 11–13 for the anal fin, 10–12 for the pelvic fins, and 14–18 for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Trout
The brown trout (''Salmo trutta'') is a species of salmonid ray-finned fish and the most widely distributed species of the genus ''Salmo'', endemic to most of Europe, West Asia and parts of North Africa, and has been widely introduced globally as a game fish, even becoming one of the world's worst invasive species outside of its native range. Brown trout are highly adaptable and have evolved numerous ecotypes/subspecies. These include three main ecotypes: a riverine ecotype called river trout or ''Salmo trutta'' morpha ''fario''; a lacustrine ecotype or ''S. trutta'' morpha ''lacustris'', also called the lake trout (not to be confused with the lake trout in North America); and anadromous populations known as the sea trout or ''S. trutta'' morpha ''trutta'', which upon adulthood migrate downstream to the oceans for much of its life and only returns to fresh water to spawn in the gravel beds of headstreams. Sea trout in Ireland and Great Britain have many regional names: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limnology
Limnology ( ; ) is the study of inland aquatic ecosystems. It includes aspects of the biological, chemical, physical, and geological characteristics of fresh and saline, natural and man-made bodies of water. This includes the study of lakes, reservoirs, ponds, rivers, springs, streams, wetlands, and groundwater.) Water systems are often categorized as either running ( lotic) or standing ( lentic). Limnology includes the study of the drainage basin, movement of water through the basin and biogeochemical changes that occur en route. A more recent sub-discipline of limnology, termed landscape limnology, studies, manages, and seeks to conserve these ecosystems using a landscape perspective, by explicitly examining connections between an aquatic ecosystem and its drainage basin. Recently, the need to understand global inland waters as part of the Earth system created a sub-discipline called global limnology. This approach considers processes in inland waters on a global scale, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
