City
A city is a human settlement of notable size.Goodall, B. (1987) ''The Penguin Dictionary of Human Geography''. London: Penguin.Kuper, A. and Kuper, J., eds (1996) ''The Social Science Encyclopedia''. 2nd edition. London: Routledge. It can be defined as a permanent and densely settled place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organisations and businesses, sometimes benefiting different parties in the process, such as improving efficiency of goods and service distribution. Historically, city-dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequences for ...

Above Mean Sea Level
Height above mean sea level is a measure of the vertical distance ( height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as '' orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called " metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called " feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying o ...

Island Park Dam
Island Park Dam is operated by the U.S. Bureau of Reclamation in Fremont County, Idaho, United States. The dam lies in Targhee National Forest near Island Park. The zoned earthfill dam was built between 1937 and 1939 as part of the Minidoka Project, which provides water to irrigate farmland in Idaho's Snake River Plain. The dam provides only water storage, impounding , which is distributed by the Cross Cut Canal to farms in Fremont and Madison counties in Idaho, and Teton County in Wyoming. The Island Park and Grassy Lake reservoirs were built as an alternative to construction of a larger project that would have flooded the Falls River area of Yellowstone National Park. Climate Island Park Dam has a humid continental climate (Köppen Köppen is a German surname.

Big Springs (Idaho)
Big Springs is the name of a first-magnitude spring located in Island Park, Idaho in Fremont County. The spring produces over 120 million gallons of water each day. It is a primary source of the North Fork or Henrys Fork of the Snake River. The other major source is the Henry's Lake outlet. The Big Springs is also famous for its large rainbow trout which congregate at the foot of the bridge waiting to be fed by the tourists (there are coin-operated feeding dispensers) No fishing is allowed until below the outlet to Henry's Lake, several miles away. Big Springs is the only first-magnitude spring that issues from rhyolite lava flows. It is a National Natural Landmark The National Natural Landmarks (NNL) Program recognizes and encourages the conservation of outstanding examples of the natural history of the United States.

Henrys Fork (Snake River)
Henrys Fork is a tributary river of the Snake River, approximately long, in southeastern Idaho in the United States. It is also referred to as the North Fork of the Snake River. Its drainage basin is , including its main tributary, the Teton River. Its mean annual discharge, as measured at river mile 9.2 (Henrys Fork near Rexburg) by the United States Geological Survey (USGS), is , with a maximum daily recorded flow of , and a minimum of . It is normally transcribed without an apostrophe. The river is named for Andrew Henry, who first entered the Snake River plateau in 1810. Employed by the Missouri Fur Company, he built Fort Henry on the upper Snake River, near modern St. Anthony, but abandoned this first American fur post west of the continental divide the following spring. Sources The river's source is at Big Springs and the Henrys Lake outlet (10 miles northwest of Big Springs). To the east is Targhee Pass, with Raynolds Pass to the northwest and Red Rock Pass to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Native Americans In The United States
Native Americans, also known as American Indians, First Americans, Indigenous Americans, and other terms, are the Indigenous peoples of the mainland United States ( Indigenous peoples of Hawaii, Alaska and territories of the United States are generally known by other terms). There are 574 federally recognized tribes living within the US, about half of which are associated with Indian reservations. As defined by the United States Census, "Native Americans" are Indigenous tribes that are originally from the contiguous United States, along with Alaska Natives. Indigenous peoples of the United States who are not listed as American Indian or Alaska Native include Native Hawaiians, Samoan Americans, and the Chamorro people. The US Census groups these peoples as " Native Hawaiian and other Pacific Islanders". European colonization of the Americas, which began in 1492, resulted in a precipitous decline in Native American population because of new diseases, wars, ethni ...

Sawtell Peak
Sawtell Peak, also spelled Sawtelle Peak is a mountain in the U.S. state of Idaho. It is located in the eastern portion of the Centennial Mountains. Sawtell Peak is located in the Caribou-Targhee National Forest roughly east of Idaho's border with Montana. The summit is located near Henrys Lake and Big Springs, headwaters of the Henrys Fork of the Snake River as well as Brower's Spring, headwaters of the Missouri River, both of which being located near the Continental Divide. It was named after Gilman Sawtell, who settled the Island Park area in 1868. There are two ridges, the north one being much less accessible. Sawtell Peak is the starting point of the easiest route to climb nearby Mount Jefferson. Geology Sawtell Peak is the easternmost peak in the Centennial Range, which run east to west, contrary to many other fault block ranges in the Basin and Range Province. This east to west structure is likely due to movement with the Yellowstone Hotspot. The mountain and surrou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Jefferson (Bitterroot Range)
Mount Jefferson is a mountain located on the Continental Divide between Fremont County of northeastern Idaho and Beaverhead County of southwestern Montana. Mount Jefferson is the highest point of the Centennial Mountains, whose crest runs along the Continental Divide and can be climbed using a class 2 route (scramble) from the access road to neighboring Sawtell Peak. The south and west slopes of Mount Jefferson drain into Hell Roaring Creek, thence into Red Rock Creek, the Red Rock River, the Beaverhead River, the Jefferson River, the Missouri River, the Mississippi River, and into the Gulf of Mexico. Brower's Spring, the source of Hell Roaring Creek, on the mountain's east flank in Montana, is considered the absolute headwaters of the Missouri River. The northeast slope of Mount Jefferson drains into the South Fork of Duck Creek, thence into Henrys Lake, the Henrys Fork of the Snake River, the Columbia River, and into the Pacific Ocean. The mountain is named for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henrys Lake
Henrys Lake is a small, shallow alpine lake in the western United States, in eastern Idaho. Approximately in area, at in length and in width, its surface elevation is above sea level. It is on the southwest side of the Henrys Lake Mountains of northern Fremont County, approximately two miles south of the continental divide along the Montana state line, just west of Targhee Pass and north of Sawtell Peak. The lake provides the headwaters of the Henrys Fork, a tributary of the Snake River. The lake lies less than across the continental divide from the headwaters of the Missouri River in southwestern Montana. It is due west of the western boundary of Yellowstone National Park, located in an enclave of Caribou-Targhee National Forest. A dam built at the outlet of Henrys Lake in 1923 dramatically increased the surface area of the lake. Springs are found around the shoreline at Staley Springs, Pintail Point, Kelly Springs, the Cliffs, and along the northshore of the lake. ...

Yellowstone Caldera
The Yellowstone Caldera, sometimes referred to as the Yellowstone Supervolcano, is a volcanic caldera and supervolcano in Yellowstone National Park in the Western United States. The caldera and most of the park are located in the northwest corner of Wyoming. The caldera measures , and postcaldera lavas spill out a significant distance beyond the caldera proper. The caldera formed during the last of three supereruptions over the past 2.1 million years: the Huckleberry Ridge eruption 2.1 million years ago (which created the Island Park Caldera and the Huckleberry Ridge Tuff), the Mesa Falls eruption 1.3 million years ago (which created the Henry's Fork Caldera and the Mesa Falls Tuff), and the Lava Creek eruption approximately 640,000 years ago (which created the Yellowstone Caldera and the Lava Creek Tuff). Volcanoes at Yellowstone Volcanism at Yellowstone is relatively recent, with calderas created by large eruptions that took place 2.1 million, 1.3 million, and 640,000 y ...

Island Park Caldera
The Island Park Caldera, in the U.S. states of Idaho and Wyoming, is one of the world's largest calderas, with approximate dimensions of 80 by 65 km. Its ashfall is the source of the Huckleberry Ridge Tuff that is found from southern California to the Mississippi River near St. Louis. This super-eruption of approximately occurred 2.1 Ma (million years ago) and produced 2,500 times as much ash as the 1980 eruption of Mount St. Helens. Island Park Caldera has the smaller and younger Henry's Fork Caldera nested inside it. The caldera clearly visible today is the later Henry's Fork Caldera, which is the source of the Mesa Falls Tuff. It was formed 1.3 Ma in an eruption of more than . The two nested calderas share the same rim on their western sides, but the older Island Park Caldera is much larger and more oval and extends well into Yellowstone National Park.Newhall and Daniel Dzurisin, 1988, "Historical Unrest at Large Calderas of the World", ''U.S. Geological Survey Bul ...
