Gunsight Butte
Gunsight Butte is a 4,678-foot (1,426 meter) elevation sandstone summit located in Glen Canyon National Recreation Area, in Kane County of southern Utah. It is situated northeast of the town of Page. Gunsight Butte is an island that towers nearly 1,000 feet above Lake Powell when the lake is full. This iconic landmark of the Lake Powell area is a butte composed primarily of Entrada Sandstone, similar to Padres Butte to the east-southeast, and Dominguez Butte to the southeast. The Entrada Sandstone of Gunsight Butte is overlain by Romana Sandstone, and capped by Morrison Formation. The Entrada Sandstone, which was originally deposited as sandy mud on a tidal flat, is believed to have formed about 160 million years ago during the Jurassic period as a giant sand sea, the largest in Earth's history. According to the Köppen climate classification system, Gunsight Butte is located in an arid climate zone with hot, very dry summers, and chilly winters with very little snow. See al ...

Glen Canyon National Recreation Area
Glen Canyon National Recreation Area (shortened to Glen Canyon NRA or GCNRA) is a national recreation area and conservation unit of the United States National Park Service that encompasses the area around Lake Powell and lower Cataract Canyon in Utah and Arizona, covering of mostly rugged high desert terrain. The recreation area is named for Glen Canyon, which was flooded by the Glen Canyon Dam, completed in 1966, and is now mostly submerged beneath the waters of Lake Powell. Glen Canyon NRA borders Capitol Reef National Park and Canyonlands National Park on the north, Grand Staircase–Escalante National Monument on the west, Vermilion Cliffs National Monument and the northeasternmost reaches of Grand Canyon National Park on the southwest, and the Navajo Nation on the southeast. The southwestern end of Glen Canyon NRA in Arizona can be accessed via U.S. Route 89 and State Route 98. State Route 95 and State Route 276 lead to the northeastern end of the recreation area in Uta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dominguez Butte
Dominguez Butte is a 4,476-foot (1,364 meter) elevation sandstone summit located south of Lake Powell, in San Juan County of southern Utah. It is situated on Navajo Nation land, northeast of the town of Page, and towers over 700 feet above the surrounding terrain as a landmark of the area. Dominguez Butte has a brief appearance in the 1968 film ''Planet of the Apes'', when a spaceship crash lands in Lake Powell. Geology Dominguez Butte is a butte composed primarily of Entrada Sandstone, similar to Padres Butte to the north, and Boundary Butte to the south. The Entrada Sandstone overlays Carmel Formation, and below that Page Sandstone at lake level. Above the Entrada layers is Romana Sandstone capped by Morrison Formation. It is located in the southern edge of the Great Basin Desert on the Colorado Plateau. Precipitation runoff from this feature drains into the Colorado River watershed.

Buttes Of Utah
__NOTOC__ In geomorphology, a butte () is an isolated hill with steep, often vertical sides and a small, relatively flat top; buttes are smaller landforms than mesas, plateaus, and tablelands. The word ''butte'' comes from a French word meaning knoll (but of any size); its use is prevalent in the Western United States, including the southwest where ''mesa'' (Spanish for "table") is used for the larger landform. Due to their distinctive shapes, buttes are frequently landmarks in plains and mountainous areas. To differentiate the two landforms, geographers use the rule of thumb that a mesa has a top that is wider than its height, while a butte has a top that is narrower than its height. Formation Buttes form by weathering and erosion when hard caprock overlies a layer of less resistant rock that is eventually worn away. The harder rock on top of the butte resists erosion. The caprock provides protection for the less resistant rock below from wind abrasion which leaves it standing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of Kane County, Utah
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features.

Barry Goldwater
Barry Morris Goldwater (January 2, 1909 – May 29, 1998) was an American politician and United States Air Force officer who was a five-term U.S. Senator from Arizona (1953–1965, 1969–1987) and the Republican Party nominee for president of the United States in 1964. Goldwater is the politician most often credited with having sparked the resurgence of the American conservative political movement in the 1960s. Despite his loss of the 1964 U.S. presidential election in a landslide, many political pundits and historians believe he laid the foundation for the conservative revolution to follow, as the grassroots organization and conservative takeover of the Republican party began a long-term realignment in American politics, which helped to bring about the "Reagan Revolution" of the 1980s. He also had a substantial impact on the American libertarian movement. Goldwater was born in Phoenix in what was then the Arizona Territory, where he helped manage his family's department ...

Arid Climate
The desert climate or arid climate (in the Köppen climate classification ''BWh'' and ''BWk''), is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive. Covering 14.2% of earth's land area, hot deserts are the second most common type of climate on earth after the polar climate. There are two variations of a desert climate according to the Köppen climate classification: a hot desert climate (''BWh''), and a cold desert climate (''BWk''). To delineate "hot desert climates" from "cold desert climates", there are three widely used isotherms: most commonly a mean annual temperature of , or sometimes the coldest month's mean temperature of , so that a location with a ''BW'' type climate with the appropriate temperature above whichever isotherm is being used is classified as "hot arid subtyp ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morrison Formation
The Morrison Formation is a distinctive sequence of Late Jurassic, Upper Jurassic sedimentary rock found in the western United States which has been the most fertile source of dinosaur fossils in North America. It is composed of mudstone, sandstone, siltstone, and limestone and is light gray, greenish gray, or red. Most of the fossils occur in the green siltstone beds and lower sandstones, relics of the rivers and floodplains of the Jurassic period. It is centered in Wyoming and Colorado, with outcrops in Montana, North Dakota, South Dakota, Nebraska, Kansas, the panhandles of Oklahoma and Texas, New Mexico, Arizona, Utah, and Idaho. Equivalent rocks under different names are found in Canada. It covers an area of 1.5 million square kilometers (600,000 square miles), although only a tiny fraction is exposed and accessible to geologists and Paleontology, paleontologists. Over 75% is still buried under the prairie to the east, and much of its western paleogeographic extent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caprock
Caprock or cap rock is a more resistant rock type overlying a less resistant rock type,Kearey, Philip (2001). ''Dictionary of Geology'', 2nd ed., Penguin Reference, London, New York, etc., p. 41.. . analogous to an upper crust on a cake that is harder than the underlying layer. Description The Niagara Escarpment, over which Niagara Falls flows, is an example of a scarp or escarpment. At Niagara Falls, the caprock is the riverbed above the falls, and is what prevents the river from eroding the face of the falls very quickly. In the photo, the dark thin layer in the foreground where water is not yet running, is the caprock. The Niagara caprock is made of dolomitic limestone. Other common types of caprock are sandstone and mafic rock. In processes such as scarp retreat, the caprock controls the rate of erosion of the scarp. As the softer rock is cut away, periodically the caprock shears off. Caprock is also found in salt domes and on the top of mesa formations. Petroleum In the ...

Padres Butte
Padres Butte is a butte near the tip of Padre Point on the south shore of Lake Powell in San Juan County, Utah, United States. Description The summit of the butte has an elevation of . It was formerly an island in the man-made lake, but land connecting the butte with the rest of Padre Point has been exposed as the lake's water levels have declined. Padres Butte marks the site of the historical Crossing of the Fathers, a series of sand bars along the great bend in the Colorado River a mile west of the butte that once offered a fordable crossing of the river. This geographical feature's name was officially adopted in 1961 by the U.S. Board on Geographic Names. According to the Köppen climate classification system, Gregory Butte is located in an arid climate zone with hot, very dry summers, and chilly winters with very little snow.
