Navajo National Monument
Navajo National Monument is a National Monument located within the northwest portion of the Navajo Nation territory in northern Arizona, which was established to preserve three well-preserved cliff dwellings of the Ancestral Puebloan people: Keet Seel (Broken Pottery) (), Betatakin (Ledge House) (), and Inscription House (). The monument is high on the Shonto plateau, overlooking the Tsegi Canyon system, west of Kayenta, Arizona. It features a visitor center with a museum, three short self-guided trails, two small campgrounds, and a picnic area. The Sandal Trail is an accessible self-guided roundtrip trail that ends at an overlook of the Betatakin ruins across the 560-foot-deep (170 m) Betatakin Canyon. The overlook is the only point in the monument where visitors can view the cliff dwelling other than on the guided tours. Rangers guide visitors on free (3-5 hour long) tours of the Betatakin cliff dwellings and on roundtrip back-country hikes to the Keet Seel. The Inscription ...

Cliff Dwelling
In archaeology, cliff dwellings are dwellings formed by using niches or caves in high cliffs, and sometimes with excavation or additions in the way of masonry. Two special types of cliff dwelling are distinguished by archaeologists: the cliff-house, which is actually built on levels in the cliff, and the cavate, which is dug out, by using natural recesses or openings. Rock-cut architecture generally refers to rather grander temples, but also tombs, cut into living rock, although for example the Ajanta Caves in India, of the 2nd century BCE to 5th century CE, probably housed several hundred Buddhist monks and are cut into a cliff, as are the Mogao Caves in China. Famous cliff dwellings are found around the world. In China, the Guyaju Caves located near Dongmenying, Yanqing District, Beijing are a cave complex of many rock hewn dwellings that form a community. In the United States and Mexico, among the canyons of the southwest, in Arizona, New Mexico, Utah, Colorado, and Chihu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Wetherill
Richard Wetherill (1858–1910), a member of a Colorado ranching family, was an amateur archaeologist who discovered, researched and excavated sites associated with the Ancient Pueblo People. He is credited with the rediscovery of Cliff Palace in Mesa Verde in Colorado and was responsible for initially selecting the term ''Anasazi'', Navajo for ''ancient enemies,'' as the name for these ancient people. He also excavated Kiet Seel ruin, now in Navajo National Monument in northeastern Arizona, and Pueblo Bonito in Chaco Canyon, New Mexico. Wetherill was fascinated by the ruins and artifacts of the Southwestern United States and made a living as a rancher, guide, excavator of ancient ruins, and trading post operator. He was criticized as a "pot hunter" by his archaeologist competitors, although many of the artifacts he found were sold or donated to prominent museums and his work was often financed or overseen by museums. In 1910, he was murdered in mysterious circumstances by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 (''BSk'' and ''BSh'') 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 it usually can't 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): *multiply by ...

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 cu ...

Arroyo (creek)
An arroyo (; from Spanish arroyo , "brook"), also called a wash, is a dry stream, creek, stream bed or gulch that temporarily or seasonally fills and flows after sufficient rain. Flash floods are common in arroyos following thunderstorms. ''Wadi'' (Arabic) is used in North Africa and Western Asia for similar landforms. The desert dry wash biome is restricted to the arroyos of the southwestern United States. Arroyos provide a water source to desert animals. Types and processes Arroyos can be natural fluvial landforms or constructed flood control channels. The term usually applies to a Grade (slope), sloped or mountainous terrain in xeric and desert climates. In addition: in many rural communities arroyos are also the principal transportation routes; and in many urban communities arroyos are also parks and recreational locations, often with linear multi-use bicycle, pedestrian, and equestrian trails. Flash flooding can cause the deep arroyos or deposition of sediment on flo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mesa Verde
Mesa Verde National Park is an American national park and UNESCO World Heritage Site located in Montezuma County, Colorado. The park protects some of the best-preserved Ancestral Puebloan archaeological sites in the United States. Established by Congress and President Theodore Roosevelt in 1906, the park occupies near the Four Corners region of the American Southwest. With more than 5,000 sites, including 600 cliff dwellings, it is the largest archaeological preserve in the United States. Mesa Verde (Spanish for "green table", or more specifically "green table mountain") is best known for structures such as Cliff Palace, thought to be the largest cliff dwelling in North America. Starting BC Mesa Verde was seasonally inhabited by a group of nomadic Paleo-Indians known as the Foothills Mountain Complex. The variety of projectile points found in the region indicates they were influenced by surrounding areas, including the Great Basin, the San Juan Basin, and the Rio Grande Vall ...

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.

Jacal
The jacal (həˈkɑːl; Mexican Spanish from Nahuatl ''xacalli'' contraction of ''xamitl calli''; literally "hut") is an adobe-style housing structure historically found throughout parts of the Southwestern United States and Mexico. This type of structure was employed by some aboriginal people of the Americas prior to European colonization and was later employed by both Hispanic and Non-Hispanic settlers in Texas and elsewhere. Typically, a jacal consisted of slim close-set poles tied together and filled out with mud, clay and grasses. More sophisticated structures, such as those constructed by the Ancestral Pueblo people, incorporated adobe bricks—sun-baked mud and sandstone. Jacal construction is similar to wattle and daub. However, the "wattle" portion of jacal structures consists mainly of vertical poles lashed together with cordage and sometimes supported by a pole framework, as in the pit-houses of the Basketmaker III period of the Ancestral Puebloan (a.k.a. Anasazi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kivas
A kiva is a space used by Puebloans for rites and political meetings, many of them associated with the kachina belief system. Among the modern Hopi and most other Pueblo peoples, "kiva" means a large room that is circular and underground, and used for spiritual ceremonies. Similar subterranean rooms are found among ruins in the North-American South-West, indicating uses by the ancient peoples of the region including the ancestral Puebloans, the Mogollon, and the Hohokam. Those used by the ancient Pueblos of the Pueblo I Period and following, designated by the Pecos Classification system developed by archaeologists, were usually round and evolved from simpler pit-houses. For the Ancestral Puebloans, these rooms are believed to have had a variety of functions, including domestic residence along with social and ceremonial purposes. Evolution During the late 8th century, Mesa Verdeans started building square pit structures that archeologists call protokivas. They were typ ...

Cliff Dwelling Of Keet Seel, Navajo Reservation, Kayenta, Navajo County, AZ HABS ARIZ,9-KAYT
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also featur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
