Glen Canyon
Glen Canyon is a natural canyon carved by a length of the Colorado River, mostly in southeastern and south-central Utah, in the United States. Glen Canyon starts where Narrow Canyon ends, at the confluence of the Colorado River and the Dirty Devil River. A small part of the lower end of Glen Canyon extends into northern Arizona and terminates at Lee's Ferry, near the Vermilion Cliffs. Like the Grand Canyon farther downstream, Glen Canyon is part of the immense system of canyons carved by the Colorado River and its tributaries. In 1966, a reservoir, Lake Powell, was created by the construction of the Glen Canyon Dam, in the Arizona portion of Glen Canyon near Page, inundating much of Glen Canyon under water hundreds of feet in depth. Contrary to popular belief, Lake Powell was not the result of negotiations over the controversial damming of the Green River within Dinosaur National Monument at Echo Park; the Echo Park Dam proposal was abandoned due to nationwide citizen pres ...

Glen Canyon Dam
Glen Canyon Dam is a concrete arch-gravity dam on the Colorado River in northern Arizona, United States, near the town of Page. The high dam was built by the U.S. Bureau of Reclamation (USBR) from 1956 to 1966 and forms Lake Powell, one of the largest man-made reservoirs in the U.S. with a capacity of more than . The dam is named for Glen Canyon, a series of deep sandstone gorges now flooded by the reservoir; Lake Powell is named for John Wesley Powell, who in 1869 led the first expedition to traverse the Colorado River's Grand Canyon by boat. A dam in Glen Canyon was studied as early as 1924, but these plans were initially dropped in favor of the Hoover Dam (completed in 1936) which was located in the Black Canyon. By the 1950s, due to rapid population growth in the seven U.S. and two Mexican states comprising the Colorado River Basin, the Bureau of Reclamation deemed the construction of additional reservoirs necessary. Contrary to popular belief, Lake Powell was not th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colorado River
The Colorado River ( es, Río Colorado) is one of the principal rivers (along with the Rio Grande) in the Southwestern United States and northern Mexico. The river drains an expansive, arid watershed that encompasses parts of seven U.S. states and two Mexican states. The name Colorado derives from the Spanish language for "colored reddish" due to its heavy silt load. Starting in the central Rocky Mountains of Colorado, it flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora. Known for its dramatic canyons, whitewater rapids, and eleven U.S. National Parks, the Colorado River and its tributaries are a vital source of water for 40 million people. An extensive system of dams ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glen Canyon Dam MC
A glen is a valley, typically one that is long and bounded by gently sloped concave sides, unlike a ravine, which is deep and bounded by steep slopes. Whittow defines it as a "Scottish term for a deep valley in the Highlands" that is "narrower than a strath".. The word is Goidelic in origin: ''gleann'' in Irish and Scottish Gaelic, ''glion'' in Manx. The designation "glen" also occurs often in place names. Etymology The word is Goidelic in origin: ''gleann'' in Irish and Scottish Gaelic, ''glion'' in Manx. In Manx, ''glan'' is also to be found meaning glen. It is cognate with Welsh ''glyn''. Examples in Northern England, such as Glenridding, Westmorland, or Glendue, near Haltwhistle, Northumberland, are thought to derive from the aforementioned Cumbric cognate, or another Brythonic equivalent. This likely underlies some examples in Southern Scotland. As the name of a river, it is thought to derive from the Irish word ''glan'' meaning clean, or the Welsh word ''gleindid'' ...

Sierra Club
The Sierra Club is an environmental organization with chapters in all 50 United States, Washington D.C., and Puerto Rico. The club was founded on May 28, 1892, in San Francisco, California, by Scottish-American preservationist John Muir, who became the first president as well as the longest-serving president, at approximately 20 years in this leadership position. The Sierra Club operates only in the United States and holds the legal status of 501(c)(4) nonprofit social welfare organization. Sierra Club Canada is a separate entity. Traditionally associated with the progressive movement, the club was one of the first large-scale environmental preservation organizations in the world, and currently engages in lobbying politicians to promote environmentalist policies. Recent focuses of the club include promoting sustainable energy and mitigating global warming, as well as opposition to the use of coal, hydropower and nuclear power. The club is known for its political endor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fremont People
The Fremont culture or Fremont people is a pre-Columbian archaeological culture which received its name from the Fremont River in the U.S. state of Utah, where the culture's sites were discovered by local indigenous peoples like the Navajo and Ute. In Navajo culture, the pictographs are credited to people who lived before the flood. The Fremont River itself is named for John Charles Frémont, an American explorer. It inhabited sites in what is now Utah and parts of Nevada, Idaho, Wyoming and Colorado from AD 1 to 1301 (2,000–700 years ago). It was adjacent to, roughly contemporaneous with, but distinctly different from the Ancestral Pueblo peoples located to their south. Location Fremont Indian State Park in the Clear Creek Canyon area in Sevier County Utah contains the biggest Fremont culture site in Utah. Thousand-year-old pit houses, petroglyphs, and other Fremont artifacts were discovered at Range Creek, Utah. Nearby Nine Mile Canyon has long been known for it ...

Hopi
The Hopi are a Native American ethnic group who primarily live on the Hopi Reservation in northeastern Arizona, United States. As of the 2010 census, there are 19,338 Hopi in the country. The Hopi Tribe is a sovereign nation within the United States and has government-to-government relations with the United States federal government. Particular villages retain autonomy under the Hopi Constitution and Bylaws. The Hopi language is one of 30 in the Uto-Aztecan language family. The majority of Hopi people are enrolled in the Hopi Tribe of Arizona but some are enrolled in the Colorado River Indian Tribes. The Hopi Reservation covers a land area of . The Hopi encountered Spaniards in the 16th century, and are historically referred to as Pueblo people, because they lived in villages (''pueblos'' in the Spanish language). The Hopi are thought to be descended from the Ancestral Puebloans ( Hopi: ''Hisatsinom''), who constructed large apartment-house complexes and had an advanced c ...

Pueblo III Era
The Pueblo III Period (AD 1150 to AD 1350) was the third period, also called the "Great Pueblo period" when Ancestral Puebloans lived in large cliff-dwelling, multi-storied pueblo, or cliff-side talus house communities. By the end of the period, the ancient people of the Four Corners region migrated south into larger, centralized pueblos in central and southern Arizona and New Mexico. The Pueblo III Period (Pecos Classification) is roughly the same as the "Great Pueblo Period" and "Classic Pueblo Period" (AD 1100 to AD 1300). It is preceded by the Pueblo II Period, and is followed by the Pueblo IV Period. Architecture During the Pueblo III Period most people lived in communities with large multi-storied dwellings. Some moved into community centers at pueblos canyon heads, such as Sand Canyon and Goodman Point pueblos in the Montezuma Valley; others moved into cliff dwellings on canyon shelves such as Mesa Verde or Keet Seel in the Navajo National Monument.

Pueblo II Era
The Pueblo II Period (AD 900 to AD 1150) was the second pueblo period of the Ancestral Puebloans of the Four Corners region of the American southwest. During this period people lived in dwellings made of stone and mortar, enjoyed communal activities in kivas, built towers and dams for water conservation, and implemented milling bins for processing maize. Communities with low-yield farms traded pottery with other settlements for maize. The Pueblo II Period (Pecos Classification) is roughly similar to the second half of the "Developmental Pueblo Period" (AD 750 to AD 1100). It is preceded by the Pueblo I Period, and is followed by the Pueblo III Period. Architecture Villages were larger and had more community buildings than in the Pueblo I Period. Structures were generally made of stone masonry. By AD 1075, double-coursed masonry was sometimes used, which allowed for second story construction.

Pueblo I Era
The Pueblo I Period (750 to 900) was the first period in which Ancestral Puebloans began living in pueblo structures and realized an evolution in architecture, artistic expression, and water conservation. Pueblo I, a Pecos Classification, is similar to the early "Developmental Pueblo Period" of 750 to 1100. It is preceded by the Basketmaker III Period, and is followed by the Pueblo II Period. Architecture People constructed and lived in pueblos, which were surface level, flat-roofed homes. At the beginning of the period pueblos were made with jacal construction. Wooden posts were used to create a frame to supported woven material and a covering of mud. Later in the period, stone slabs were sometimes used around the dwelling foundation.Ancestral Puebloan Chronology (teaching aid).''

Basketmaker Culture
The Basketmaker culture of the pre-Ancestral Puebloans began about 1500 BC and continued until about AD 750 with the beginning of the Pueblo I Era. The prehistoric American southwestern culture was named "Basketmaker" for the large number of baskets found at archaeological sites of 3,000 to 2,000 years ago. The people Well-preserved mummies found in dry caves provide insight into the ancient Basketmakers. Women were about 5 feet tall and men were 3 to 4 inches taller. They had long, narrow faces and medium to stocky build. Their skin varied from light to dark brown and they had brown or black hair and eyes. Fancy hairstyles were sometimes worn by men and infrequently by women. Women's hair may have been cut short; Significant quantities of rope made of human hair have been recovered and since it was more likely that men had fancy hairstyles, the hair for rope may have come from women. The Basketmakers wore sandals made of woven yucca fibers or strips of leaves. Ther ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basketmaker III Era
The Basketmaker III Era () also called the "Modified Basketmaker" period, was the third period in which Ancient Pueblo People were cultivating food, began making pottery and living in more sophisticated clusters of pit-house dwellings. Hunting was easier with the adoption of the bow and arrow. The Basketmaker III Era is preceded by the Late Basketmaker II Era, and is followed by the Pueblo I Era. Architecture In the Basketmaker III Era people continued to live in pit-houses, but the architecture changed. Now the houses were larger, included division on the space into sections, a large central hearth, addition of vestibules, and slabs of stone were used to line the walls.''Ancestral Pueblo – Basketmaker III''.
