Mount Ellen (Utah)
Mount Ellen is a mountain located in Garfield County, Utah, United States. Description Mount Ellen's North Summit Ridge is the highest point in the Henry Mountains; it is also the highest point in Garfield County. It can be reached by a short hike from an unpaved road. These mountains were the last to be surveyed by the USGS in the lower 48 states. The mountain can be seen from as far as Mount Peale in the La Sal Mountains of eastern Utah. Mount Ellen is an ultra prominent peak, meaning that it has more than of topographic prominence, standing out considerably from nearby mountains. It stands in the watershed of the Fremont River, which together with Muddy Creek forms the Dirty Devil River, which drains into the Colorado River, and ultimately into the Gulf of California in Mexico. The Paiute name for Mount Ellen was Un tar re. It was also referred to as First Mountain. After climbing to the summit in June 1872, Almon Harris Thompson named it for his wife Ellen.

Dirty Devil River
The Dirty Devil River is an tributary of the Colorado River, located in the U.S. state of Utah. It flows through southern Utah from the confluence of the Fremont River and Muddy Creek before emptying into the Colorado River at Lake Powell. Course The Dirty Devil River is formed in Wayne County near Hanksville at the confluence of the Fremont River and Muddy Creek. It flows generally southward through a canyon in Wayne and Garfield counties. Its lower flows through Glen Canyon National Recreation Area, where it finally disembogues into the Colorado River at a point that is now submerged beneath Lake Powell. The canyon carved by the river is particularly isolated and seldom visited compared to other natural areas in the region. The average discharge is approximately 446 cubic feet per second. History The Dirty Devil River was named by the 1869 Powell Geographic Expedition led by John Wesley Powell, which explored much of the Colorado River and its tributaries. It was named ...

List Of Ultras Of The United States
The following sortable table comprises the 200 most topographically prominent mountain peaks of the United States of America. The summit of a mountain or hill may be measured in three principal ways: #The topographic elevation of a summit measures the height of the summit above a geodetic sea level.All elevations in the 48 states of the contiguous United States include an elevation adjustment from the National Geodetic Vertical Datum of 1929 (NGVD 29) to the North American Vertical Datum of 1988 (NAVD 88). For further information, please see this United States National Geodetic Surveybr>noteIf the elevation or prominence of a summit is calculated as a range of values, the arithmetic mean is shown. #The topographic prominence of a summit is a measure of how high the summit rises above its surroundings.The topographic prominence of a summit is the topographic elevation difference between the summit and its highest or key col to a higher summit.

Heliograph
A heliograph () is a semaphore system that signals by flashes of sunlight (generally using Morse code) reflected by a mirror. The flashes are produced by momentarily pivoting the mirror, or by interrupting the beam with a shutter. The heliograph was a simple but effective instrument for instantaneous optical communication over long distances during the late 19th and early 20th century. Its main uses were military, survey and forest protection work. Heliographs were standard issue in the British and Australian armies until the 1960s, and were used by the Pakistani army as late as 1975. Description There were many heliograph types. Most heliographs were variants of the British Army Mance Mark V version (Fig.1). It used a mirror with a small unsilvered spot in the centre. The sender aligned the heliograph to the target by looking at the reflected target in the mirror and moving their head until the target was hidden by the unsilvered spot. Keeping their head still, they then adj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Wesley Powell
John Wesley Powell (March 24, 1834 – September 23, 1902) was an American geologist, U.S. Army soldier, explorer of the American West, professor at Illinois Wesleyan University, and director of major scientific and cultural institutions. He is famous for his 1869 geographic expedition, a three-month river trip down the Green and Colorado rivers, including the first official U.S. government-sponsored passage through the Grand Canyon. Powell was appointed by US President James A. Garfield to serve as the second director of the U.S. Geological Survey (1881–1894) and proposed, for development of the arid West, policies that were prescient for his accurate evaluation of conditions. Two years prior to his service as director of the U.S. Geological Survey, Major Powell had become the first director of the Bureau of Ethnology at the Smithsonian Institution where he supported linguistic and sociological research and publications.

Almon Harris Thompson
Almon Harris Thompson (September 24, 1839 – July 31, 1906), also known as A. H. Thompson, was an American topographer, geologist, explorer, educator and Civil War veteran. Often called "The Professor" or simply "Prof", Thompson is perhaps best known for being second in command of John Wesley Powell's Second Geographical Expedition (1871–1875), a federally funded scientific expedition that retraced the route of Powell's original expedition in order to further explore and map the drainages and canyons of the Green and Colorado Rivers in what is now southern Utah and northern Arizona. Thompson's diary of the expedition was originally published in the Utah Historical Quarterly in 1939. Through his work on the Powell expeditions and later as a geographer at the U.S. Geological Survey, he was responsible for naming many geographic locations in the Western United States. Thompson is also known for being a founding member of the National Geographic Society. Early life and education ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Paiute
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 have been granted federal recognition on several reservations. The first European contact with the Southern Paiute occurred in 1776, when fathers Silvestre Vélez de Escalante and Francisco Atanasio Domínguez encountered them during an attempt to find an overland route to the missions of California. They noted that some of the Southern Paiute men "had thick beards and were thought to look more in appearance like Spanish men than native Americans". Before this date, the Southern Paiute suffered slave raids by the Navajo and the Ute. The arrival of Spanish and later Euro-American explorers into their territory increased slave raiding by other tribes. In 1851, Mormon settlers strategically occupied Paiute water sources, which created a depend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
