Rooster Rock (Arizona)
Rooster Rock is a summit in Apache County, Arizona, United States. Description Rooster Rock is situated southeast of the Monument Valley visitor center on Navajo Nation land. Precipitation runoff from this butte's slopes drains into Gypsum Creek, which is a tributary of the San Juan River. Topographic relief is significant, as the summit rises nearly above the surrounding terrain in 0.25 mile (0.4 km). The nearest higher neighbor is Meridian Butte, to the south-southwest. The landform's descriptive toponym has been officially adopted by the U.S. Board on Geographic Names. Geology Rooster Rock is a butte composed of two principal strata. The bottom layer is slope-forming Organ Rock Shale and the upper stratum is cliff-forming De Chelly Sandstone. The rock was deposited during the Permian period. The buttes and mesas of Monument Valley are the result of the Organ Rock Shale being more easily eroded than the overlaying sandstone. Climate Spring and fall are the most ...

Navajo Nation
The Navajo Nation (), also known as Navajoland, is an Indian reservation of Navajo people in the United States. It occupies portions of northeastern Arizona, northwestern New Mexico, and southeastern Utah. The seat of government is located in Window Rock, Arizona. At roughly , the Navajo Nation is the largest Indian reservation in the United States, exceeding the size of List of U.S. states and territories by area, ten U.S. states. It is one of the few reservations whose lands overlap the nation's traditional homelands. In 2010, the reservation was home to 173,667 out of 332,129 Navajo tribal members; the remaining 158,462 tribal members lived outside the reservation, in urban areas (26%), border towns (10%), and elsewhere in the U.S. (17%). In 2020, the number of tribal members increased to 399,494, surpassing the Cherokee Nation as the largest tribal group by enrollment. The U.S. Mexican Cession, gained ownership of what is today Navajoland in 1848 following the Mexican–A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Chelly Sandstone
The Yeso Group is a group of geologic formations in New Mexico. It contains fossils characteristic of the Kungurian Age of the early Permian Period. Description The Yeso Group is lithologically complex, ranging from marine shelf carbonate rock to the south through shoreline and sabkha beds to eolian dune and sheet sand deposits to the north. It is exposed in the mountains and other uplifts bordering the Rio Grande Rift and in the Pecos River valley. It is present in the subsurface in the Raton Basin. The group records a major marine transgression from the south during the early Leonardian (Kungurian). In the Jemez Mountains, the group consists of massive cross-bedded lower beds ( De Chelly Sandstone) and thinner upper beds ( San Ysidro Formation) suggesting a more fluvial depositional environment. The Yeso Group is exposed extensively in the Jemez Mountains, but pinches out in the northern Jemez, delineating the northern limit of the dune field from which it arose. Fa ...

Geography Of The Navajo Nation
Geography (from Ancient Greek ; combining 'Earth' and 'write', literally 'Earth writing') is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines." Origins of many of the concepts in geography can be traced to Greek Eratosthenes of Cyrene, who may have coined the term "geographia" (). The first recorded use of the word γεωγραφία was as the title of a book by Greek scholar Claudius Ptolemy (100 – 170 AD). This work created the so-called "Ptolemaic tradition" of geography, which included "Ptolemaic cartographic theory." ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of Apache County, Arizona
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). 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 oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodi ...

Spearhead Mesa
Spearhead Mesa is a summit in Navajo County, Arizona, United States. Description Spearhead Mesa is situated southeast of the Monument Valley visitor center on Navajo Nation land. The nearest higher neighbor is the iconic East Mitten Butte, to the north-northwest. Precipitation runoff from this mesa's slopes drains into Gypsum Creek which is a tributary of the San Juan River. Topographic relief is significant as the summit rises above the surrounding terrain in one-quarter mile (0.4 km). The landform's toponym has been officially adopted by the U.S. Board on Geographic Names. The spearhead name refers to a sandstone spire above Artist Point that resembles the spear of an arrow. Geology Spearhead Mesa is a mesa composed of three principal strata. The bottom layer is slope-forming Organ Rock Shale, the next stratum is cliff-forming De Chelly Sandstone, and the upper layer is Moenkopi Formation with a Shinarump Conglomerate caprock. The rock ranges in age from Permian at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Totem Pole (Monument Valley)
The Totem Pole is a pillar or rock spire found in Monument Valley. It is a highly eroded remnant of a butte. Deserts at the end of the Permian period, 260 million years ago, formed the De Chelly and Wingate Sandstones that make up the buttes, totems, and mesas in Monument Valley. The Totem Pole rises next to a gathering of thicker spires the Navajo called Yei Bi Chei and can be seen via a self-guided Valley Drive. Rock climbing The Totem Pole was first climbed June 11–13, 1957 by Bill Feuerer, Jerry Gallwas, Mark Powell and Don Wilson. The first ascent route is rated 5.10 YDS A2 in the Yosemite Decimal System. A second route called "Never Never Land" was climbed in 1979. Parts of the 1975 thriller film ''The Eiger Sanction'' (U.S. director Clint Eastwood) were filmed at Totem Pole. According to author Ron Hogan, " addition to directing and starring in The Eiger Sanction, Clint Eastwood did all his own stunts during the mountain-climbing sequences." Hogan further adds tha ...

Diurnal Temperature Variation
In meteorology, diurnal temperature variation is the variation between a high air temperature and a low temperature that occurs during the same day. Temperature lag Temperature lag, also known as thermal inertia, is an important factor in diurnal temperature variation. Peak daily temperature generally occurs ''after'' noon, as air keeps absorbing net heat for a period of time from morning through noon and some time thereafter. Similarly, minimum daily temperature generally occurs substantially after midnight, indeed occurring during early morning in the hour around dawn, since heat is lost all night long. The analogous annual phenomenon is seasonal lag. As solar energy strikes the Earth's surface each morning, a shallow layer of air directly above the ground is heated by conduction. Heat exchange between this shallow layer of warm air and the cooler air above is very inefficient. On a warm summer's day, for example, air temperatures may vary by from just above the ground t ...

Semi-arid Climate
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSh'' and ''BSk'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as they usually cannot support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): * ...

Köppen Climate Classification
The Köppen climate classification divides Earth climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. 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'' indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the ''A'' group, indicated by the third letter for climates in ''B'', ''C'', ''D'', and the second letter for climates in ''E''. Other examples include: ''Cfb'' indicating an oceanic climate with warm summers as indicated by the ending ''b.'', while ''Dwb'' indicates a semi-Monsoon continental climate, monsoonal continental climate ...

Totem Pole, Monument Valley
A totem (from or ''doodem'') is a spirit being, sacred object, or symbol that serves as an emblem of a group of people, such as a family, clan, lineage, or tribe, such as in the Anishinaabe clan system. While the word ''totem'' itself is an anglicisation of the Ojibwe term (and both the word and beliefs associated with it are part of the Ojibwe language and culture), belief in tutelary spirits and deities is not limited to the Ojibwe people. Similar concepts, under differing names and with variations in beliefs and practices, may be found in a number of cultures worldwide. The term has also been adopted, and at times redefined, by anthropologists and philosophers of different cultures. Contemporary neoshamanic, New Age, and mythopoetic men's movements not otherwise involved in the practice of a traditional, tribal religion have been known to use "totem" terminology for the personal identification with a tutelary spirit or spirit guide.
