Gallina Blanca
The Gallina or Largo-Gallina culture was an occupation sequence during the pre- Hispanic period in the American Southwest from approximately 1050 to 1300. The culture was located in north-central New Mexico roughly north of the Jemez Mountains, and was named after the Rio Gallina (and Largo Canyon), which runs through the region. Ancestry The Gallina are tentatively linked to the Rosa Phase of the Ancestral Puebloans.Ford et al. 1972 Evidence indicates a connection to the Rosa people, due to similar skills such as basket weaving, black on white pottery, and architecture. They also have similar ornaments such as shells pierced for stringing, bone beads, and stone pipes. Tools and artifacts Artifacts from the Gallina time period are often hard to classify. For example, what archeologists originally classified as scrapers later proved to be knives. Frequently, assessing an object itself is not enough; it becomes necessary to analyze type as well as evidence of use and wear. ...

Spanish Colonization Of The Americas
Spain began colonizing the Americas under the Crown of Castile and was spearheaded by the Spanish . The Americas were invaded and incorporated into the Spanish Empire, with the exception of Brazil, British America, and some small regions of South America and the Caribbean. The crown created civil and religious structures to administer the vast territory. The main motivations for colonial expansion were profit through resource extraction and the spread of Catholicism by converting indigenous peoples. Beginning with Columbus's first voyage to the Caribbean and gaining control over more territory for over three centuries, the Spanish Empire would expand across the Caribbean Islands, half of South America, most of Central America and much of North America. It is estimated that during the colonial period (1492–1832), a total of 1.86 million Spaniards settled in the Americas, and a further 3.5 million immigrated during the post-colonial era (1850–1950); the esti ...

Pit House
A pit-house (or ''pit house'', ''pithouse'') is a house built in the ground and used for shelter. Besides providing shelter from the most extreme of weather conditions, these structures may also be used to store food (just like a pantry, a larder, or a root cellar) and for cultural activities like the telling of stories, dancing, singing and celebrations. General dictionaries also describe a pit-house as a ''dugout'', and it has similarities to a ''half-dugout''. In archaeology, a pit-house is frequently called a ''sunken-featured building'' and occasionally (grub-)hut or ''grubhouse'', after the German name ''Grubenhaus'' They are found in numerous cultures around the world, including the people of the Southwestern United States, the ancestral Pueblo, the ancient Fremont and Mogollon cultures, the Cherokee, the Inuit, the people of the Plateau, and archaic residents of Wyoming (Smith 2003) in North America; Archaic residents of the Lake Titicaca Basin (Craig 2005) in South Am ...

Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava Bed
Lava fields are large, mostly flat areas of surface or subaquatic lava flows. Such features are generally composed of highly fluid basalt lava, and can extend for tens or hundreds of miles across the underlying terrain. Morphology and structure The final morphology of a lava field can reveal properties such as internal structure, composition, and mechanics of the lava flow when it was fluid. The ridges and patterns on top of the lava field show the direction of the channels and the oftentimes active lava tubes that may be underneath the solidified "crust." It can also reveal whether the lava flow can be classified as pāhoehoe or 'a'ā. The two main types of lava field structures are defined as sheet flow lava and pillow lava. Sheet flow lava appears like a wrinkled or folded sheet, while pillow lava is bulbous, and often looks like a pile of pillows atop one another. An important aspect of lava flow morphology is a phenomenon known as lava flow inflation. This occurs in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dendrochronology
Dendrochronology (or tree-ring dating) is the scientific method of dating tree rings (also called growth rings) to the exact year they were formed. As well as dating them, this can give data for dendroclimatology, the study of climate and atmospheric conditions during different periods in history from wood. Dendrochronology derives from Ancient Greek (), meaning "tree", (), meaning "time", and (), "the study of". Dendrochronology is useful for determining the precise age of samples, especially those that are too recent for radiocarbon dating, which always produces a range rather than an exact date. However, for a precise date of the death of the tree a full sample to the edge is needed, which most trimmed timber will not provide. It also gives data on the timing of events and rates of change in the environment (most prominently climate) and also in wood found in archaeology or works of art and architecture, such as old panel paintings. It is also used as a check in radiocar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Florence Hawley Ellis
Florence May Hawley Ellis (née Florence May Hawley, also known as Florence Hawley Senter; September 17, 1906 – 1991) was one of the first anthropologists to work extensively on dendrochronology, or tree-ring dating. She conducted archaeological and ethnographic research in the Southwestern United States; and undertook some of the first dendrochronological research in eastern North America in the mid 20th century, examining samples from a number of archaeological sites. She was also highly regarded as a passionate teacher who pushed her students toward greatness by encouraging them to think for themselves and work hard for what they wanted to achieve. Although faced with many challenges in her career, and discriminated against for being a woman, she persevered in her research and became a great influence both for her students and for other women in her field. Background Florence Hawley was born in Cananea Sonora, Mexico where her father was chief chemist for a copper mine. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Native American Religion
Native American religions are the spiritual practices of the Native Americans in the United States. Ceremonial ways can vary widely and are based on the differing histories and beliefs of individual nations, tribes and bands. Early European explorers describe individual Native American tribes and even small bands as each having their own religious practices. Theology may be monotheistic, polytheistic, henotheistic, animistic, shamanistic, pantheistic or any combination thereof, among others. Traditional beliefs are usually passed down in the forms of oral histories, stories, allegories, and principles. Overview Beginning in the 1600s, European Christians, both Catholics and those of various Protestant denominations, sought to convert Native American tribes from their pre-existing beliefs to Christianity. After the United States gained independence in the late 1700s, its government continued to suppress Indigenous practices and promote forcible conversion. Government agen ...

Kiva
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 ...

Sipapu
A (a Hopi word) was a small hole or indentation in the floor of a (pithouse). Kivas were used by the Ancestral Puebloans and continue to be used by modern-day Puebloans. The symbolizes the portal through which their ancient ancestors first emerged to enter the present world. Hopi mythology (and similar traditions in other Pueblo cultures such as the Zuni and Acoma) states that this is the hole from which the first peoples of this world entered. As they stepped outside of the , they changed from lizard-like beings into human form. It is from this point that the "First Peoples" of the Earth began to divide and separate, becoming tribes. The original sipapu is said to be located in the Grand Canyon The Grand Canyon (, yuf-x-yav, Wi:kaʼi:la, , Southern Paiute language: Paxa’uipi, ) is a steep-sided canyon carved by the Colorado River in Arizona, United States.
