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.

Caves
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorgani ...

Edgar Lee Hewett
Edgar Lee Hewett (November 23, 1865 – December 31, 1946) was an American archaeologist and anthropologist whose focus was the Native American communities of New Mexico and the southwestern United States. He is best known for his role in gaining passage of the Antiquities Act, a pioneering piece of legislation for the conservation movement; as the founder and first director of the Museum of New Mexico; and as the first president of the New Mexico Normal School, now New Mexico Highlands University. Hewett's dealings with Maria Martinez, the matriarch potter of San Ildefonso Pueblo, were instrumental in establishing San Ildefonso as a center for Native American pottery. He helped stimulate the rebirth of pottery as a significant folk art form in the region. Hewett also had a significant role in the formation of Bandelier National Monument and Chaco Culture National Historical Park, established to preserve extensive prehistoric ruins of the Pueblo people whom he studied.

Tuff
Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Following ejection and deposition, the ash is lithified into a solid rock. Rock that contains greater than 75% ash is considered tuff, while rock containing 25% to 75% ash is described as tuffaceous (for example, ''tuffaceous sandstone''). Tuff composed of sandy volcanic material can be referred to as volcanic sandstone. Tuff is a relatively soft rock, so it has been used for construction since ancient times. Because it is common in Italy, the Romans used it often for construction. The Rapa Nui people used it to make most of the ''moai'' statues on Easter Island. Tuff can be classified as either igneous or sedimentary rock. It is usually studied in the context of igneous petrology, although it is sometimes described using sedimentological terms. Tuff is often erroneously called tufa in guidebooks and in television programmes. Volcanic ash The material that is expelled in a volcanic ...

Plaza
A town square (or square, plaza, public square, city square, urban square, or ''piazza'') is an open public space, commonly found in the heart of a traditional town but not necessarily a true geometric square, used for community gatherings. Related concepts are the civic center, the market square and the village green. Most squares are hardscapes suitable for open markets, concerts, political rallies, and other events that require firm ground. Being centrally located, town squares are usually surrounded by small shops such as bakeries, meat markets, cheese stores, and clothing stores. At their center is often a well, monument, statue or other feature. Those with fountains are sometimes called fountain squares. By country Australia The city centre of Adelaide and the adjacent suburb of North Adelaide, in South Australia, were planned by Colonel William Light in 1837. The city streets were laid out in a grid plan, with the city centre including a central public square, Vict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Masonry
Masonry is the building of structures from individual units, which are often laid in and bound together by mortar; the term ''masonry'' can also refer to the units themselves. The common materials of masonry construction are bricks, building stone such as marble, granite, and limestone, cast stone, concrete blocks, glass blocks, and adobe. Masonry is generally a highly durable form of construction. However, the materials used, the quality of the mortar and workmanship, and the pattern in which the units are assembled can substantially affect the durability of the overall masonry construction. A person who constructs masonry is called a mason or bricklayer. These are both classified as construction trades. Applications Masonry is commonly used for walls and buildings. Brick and concrete block are the most common types of masonry in use in industrialized nations and may be either load-bearing or non-load-bearing. Concrete blocks, especially those with hollow cores, offer va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bandelier Tuff
The Bandelier Tuff is a geologic formation exposed in and around the Jemez Mountains of northern New Mexico. It has a radiometric age of 1.85 to 1.25 million years, corresponding to the Pleistocene epoch. The tuff was erupted in a series of at least three caldera eruptions in the central Jemez Mountains. The Bandelier Tuff was one of the first ignimbrites recognized in the geologic record, and has been extensively studied by geologists seeking to understand the processes involved in volcanic supereruptions. Description The formation is composed of ignimbrites produced by a series of at least three Quaternary caldera eruptions that culminated in the Valles Caldera eruption 1.256 million years before the present ( Mya). The Valles Caldera is the type location for resurgent caldera eruptions, and the Bandelier Tuff was one of the earliest recognized ignimbrites. The caldera lies on the intersection of the western margin of the Rio Grande Rift and the Jemez Lineament. Here magma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potrero (landform)
A potrero is a long mesa that at one end slopes upward to higher terrain. This landform commonly occurs on the flanks of a mountain, as part of a dissected plateau. A loan word from the Spanish language, potrero is in current use in the southwestern United States, where it is sometimes translated as "tongue of land" and "enclosed piece of pasture land". In the Spanish language, however, the "tongue of land" sense is archaic. Also archaic is the related sense of potrero referring to someone who wrangles young horses (''potros'' in Spanish) kept as breeding stock (not saddle or pack stock). In Spanish, the usual sense of ''potrero'' now refers to any land (such as a ranch, open range, or community pasture) where such horses are kept. Notable examples of potreros include some of the many mesas of the Pajarito Plateau near Santa Fe, New Mexico (United States).These "finger mesas" were once a continuous deposit of compressed volcanic ash (the Bandelier Tuff). Water then cut the tuff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mortar (masonry)
Mortar is a workable paste which hardens to bind building blocks such as stones, bricks, and concrete masonry units, to fill and seal the irregular gaps between them, spread the weight of them evenly, and sometimes to add decorative colors or patterns to masonry walls. In its broadest sense, mortar includes pitch, asphalt, and soft mud or clay, as those used between mud bricks, as well as cement mortar. The word "mortar" comes from Old French ''mortier'', "builder's mortar, plaster; bowl for mixing." (13c.). Cement mortar becomes hard when it cures, resulting in a rigid aggregate structure; however, the mortar functions as a weaker component than the building blocks and serves as the sacrificial element in the masonry, because mortar is easier and less expensive to repair than the building blocks. Bricklayers typically make mortars using a mixture of sand, a binder, and water. The most common binder since the early 20th century is Portland cement, but the ancient binder lim ...

Adobe
Adobe ( ; ) is a building material made from earth and organic materials. is Spanish for ''mudbrick''. In some English-speaking regions of Spanish heritage, such as the Southwestern United States, the term is used to refer to any kind of earthen construction, or various architectural styles like Pueblo Revival or Territorial Revival. Most adobe buildings are similar in appearance to cob and rammed earth buildings. Adobe is among the earliest building materials, and is used throughout the world. Adobe architecture has been dated to before 5,100 B.C. Description Adobe bricks are rectangular prisms small enough that they can quickly air dry individually without cracking. They can be subsequently assembled, with the application of adobe mud to bond the individual bricks into a structure. There is no standard size, with substantial variations over the years and in different regions. In some areas a popular size measured weighing about ; in other contexts the size is weighi ...
