Pyramid Lake (Nevada)
Pyramid Lake is the geographic sink of the basin of the Truckee River, northeast of Reno, Nevada, United States. Pyramid Lake is the biggest remnant of ancient Lake Lahontan, the colossal inland sea that once covered most of Nevada. It is approximately 15 miles long and 11 miles wide, covering 112,000 acres entirely enclosed within the Pyramid Lake Paiute Tribe Reservation. Pyramid Lake is fed by the Truckee River, which is mostly the outflow from Lake Tahoe. The Truckee River enters Pyramid Lake at its southern end. Pyramid Lake is an endorheic lake. It has no outlet, with water left only by evaporation, or sub-surface seepage. The lake has about 10% of the area of the Great Salt Lake, but it has about 25% more volume. The salinity is approximately 1/6 that of sea water. Although clear Lake Tahoe forms the headwaters that drain to Pyramid Lake, the Truckee River delivers more turbid waters to Pyramid Lake after traversing the steep Sierra terrain and collecting moderately hi ...

Tufa
Tufa is a variety of limestone formed when carbonate minerals precipitate out of water in unheated rivers or lakes. Geothermally heated hot springs sometimes produce similar (but less porous) carbonate deposits, which are known as travertine. Tufa is sometimes referred to as (meteogene) travertine. It should not be confused with hot spring (thermogene) travertine. Tufa, which is calcareous, should also not be confused with tuff, a porous volcanic rock with a similar etymology that is sometimes also called "tufa". Classification and features Modern and fossil tufa deposits abound with wetland plants; as such, many tufa deposits are characterised by their large macrobiological component, and are highly porous. Tufa forms either in fluvial channels or in lacustrine environments. Ford and Pedley (1996) provide a review of tufa systems worldwide. Fluvial deposits Deposits can be classified by their depositional environment (or otherwise by vegetation or petrographically). P ...

Surface Runoff
Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or man-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry man-made contaminants or natural forms of pollution (such as rotting leaves). Man-made contaminants in run ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Pilger
John Richard Pilger (; born 9 October 1939) is an Australian journalist, writer, scholar, and documentary filmmaker. He has been mainly based in Britain since 1962. He was also once visiting professor at Cornell University in New York. Pilger is a strong critic of American, Australian, and British foreign policy, which he considers to be driven by an imperialist and colonialist agenda. Pilger has also criticised his native country's treatment of Indigenous Australians. He first drew international attention for his reports on the Cambodian genocide. His career as a documentary film maker began with ''The Quiet Mutiny'' (1970), made during one of his visits to Vietnam, and has continued with over 50 documentaries since. Other works in this form include ''Year Zero'' (1979), about the aftermath of the Pol Pot regime in Cambodia, and '' Death of a Nation: The Timor Conspiracy'' (1993). His many documentary films on indigenous Australians include '' The Secret Country'' (198 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Lahontan (reservoir)
Modern Lake Lahontan is a reservoir on the Carson River in northwest Nevada in the United States. It is formed by the Lahontan Dam, built in 1905 by the Bureau of Reclamation as part of the Newlands Reclamation Act and is located between Fallon, Nevada and Carson City, Nevada. The flows from the Carson River is augmented by the diversions from the Truckee River. The reservoir is maintained by the Truckee-Carson Irrigation District (TCID). The lake is named after ancient Lake Lahontan, which covered much of northwestern Nevada during the last ice age. Lake Lahontan is 17 miles (27 km) long and has 69 miles (111 km) of shoreline. It consists of several lobes connected by narrow straits. When full, it has approximately 10,000 acres (40 km²) of surface area, although it is usually less than half full by late summer. As no water rights have been allocated for recreation, the TCID could completely drain the lake to supply its irrigation customers. Submerged beneath th ...

Derby Dam
Derby Dam is a diversion dam built from 1903 to 1905 on the Truckee River, located about east of Reno in Storey and Washoe counties in Nevada, United States. It diverts water into the Truckee Canal that would otherwise enter Pyramid Lake. The canal feeds Lake Lahontan reservoir in the Carson River watershed, where it is used for irrigation. It was the first project of the newly organized U.S. Reclamation Service (known today as the U.S. Bureau of Reclamation), organized by the Reclamation Act of 1902. As a result of the diversion, Winnemucca Lake lost inflow and dried up, and Pyramid Lake lost more than in elevation, resulting in the near-extinction of the Lahontan cutthroat trout. The dam is operated by the Truckee-Carson Irrigation District. It was named after the Derby Southern Pacific Railroad station. History The dam was constructed for the U.S. Bureau of Reclamation following an authorization for construction issued on March 14, 1903. Construction commence ...

Pyramid Lake Water Level 1887-2019
A pyramid (from el, πυραμίς ') is a structure whose outer surfaces are triangular and converge to a single step at the top, making the shape roughly a pyramid in the geometric sense. The base of a pyramid can be trilateral, quadrilateral, or of any polygon shape. As such, a pyramid has at least three outer triangular surfaces (at least four faces including the base). The square pyramid, with a square base and four triangular outer surfaces, is a common version. A pyramid's design, with the majority of the weight closer to the ground and with the pyramidion at the apex, means that less material higher up on the pyramid will be pushing down from above. This distribution of weight allowed early civilizations to create stable monumental structures. Civilizations in many parts of the world have built pyramids. The largest pyramid by volume is the Great Pyramid of Cholula, in the Mexican state of Puebla. For thousands of years, the largest structures on Earth were pyram ...

Paiute War
Paiute (; also Piute) refers to three non-contiguous groups of indigenous peoples of the Great Basin. Although their languages are related within the Numic group of Uto-Aztecan languages, these three groups do not form a single set. The term "Paiute" does not refer to a single, unique, unified group of Great Basin tribes, but is a historical label comprising: * Northern Paiute people of northeastern California, northwestern Nevada, eastern Oregon, and southern Idaho * Southern Paiute people The Southern Paiute people are a tribe of Native Americans who have lived in the Colorado River basin of southern Nevada, northern Arizona, and southern Utah. Bands of Southern Paiute live in scattered locations throughout this territory and ha ... of northern Arizona, southern Nevada, and southwestern Utah * Mono people of east central California, divided into Owens Valley Paiute (Eastern Mono) and Western Mono (Monache) {{Authority control ...

Bent Pyramid
The Bent Pyramid is an ancient Egyptian pyramid located at the royal necropolis of Dahshur, approximately 40 kilometres south of Cairo, built under the Old Kingdom Pharaoh Sneferu (c. 2600 BC). A unique example of early pyramid development in Egypt, this was the second pyramid built by Sneferu. The Bent Pyramid rises from the desert at a 54-degree inclination, but the top section (above 47 metres) is built at the shallower angle of 43 degrees, lending the pyramid a visibly 'bent' appearance. Overview Archaeologists now believe that the Bent Pyramid represents a transitional form between step-sided and smooth-sided pyramids. It has been suggested that due to the steepness of the original angle of inclination the structure may have begun to show signs of instability during construction, forcing the builders to adopt a shallower angle to avert the structure's collapse. This theory appears to be borne out by the fact that the adjacent Red Pyramid, built immediately afterwards by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lahontan Cutthroat Trout
Lahontan cutthroat trout (''Oncorhynchus clarkii henshawi'') is the largest subspecies of cutthroat trout, and the state fish of Nevada. It is one of three subspecies of cutthroat trout that are listed as federally threatened. Natural history The Lahontan cutthroat is native to the drainages of the Truckee River, Humboldt River, Carson River, Walker River, Quinn River and several smaller rivers in the Great Basin of North America. These were tributaries of ancient and massive Lake Lahontan during the ice ages until the lake shrank to remnants such as Pyramid Lake and Walker Lake about 7,000 years ago, although Lake Tahoe—from which the Truckee flows to Pyramid Lake—is still a large mountain lake. In this sense, Lahontan cutthroats essentially evolved in inland ocean-like conditions. Here, Lahontan cutthroats became a large (up to 1 m or 39 in) and moderately long-lived predator of chub suckers, and other fish as long as 30 or . The trout was able to remain a ...

Tui Chub
The tui chub (''Siphateles bicolor'') is a cyprinid fish native to western North America. Widespread in many areas, it is an important food source for other fish, including the cutthroat trout. Range The tui chub's range includes the Lahontan and Central system of the Great Basin, as well as the Owens and Mojave Rivers. It is found in the Pit River and Goose Lake of the upper Central Valley, in the Klamath River system, and in the Columbia River drainage. Description The form and appearance of the tui chub is variable; many were originally described as different species by J. O. Snyder, but have since been reduced to subspecies. In general, the color is deep olive above and white below, with a smooth variation in shading along the sides, and a brassy reflection. Fins are olive and sometimes tinted with red. The pectoral fins are far forward and low on the body. Length has been recorded at up to , but is more typical. Habitat and behavior Tui chubs are found ...
