Big Eddy Site
The Big Eddy Site ( 23CE426) is an archaeological site located in Cedar County, Missouri, which was first excavated in 1997 and is now threatened due to erosion by the Sac River. Location and general description The Sac River has created a cut bank, some 5.2 meters high, revealing a rare site similar to the Rodgers Formation of the neighboring Pomme de Terre valley (Lopinot et al. 1998:39-40). Haynes (1976:58-59) describes the deposits in the area of Rodgers Cave as flood plain deposits which have accumulated slowly through annual flooding. Periodically, the river would downcut deeply enough to prevent further flooding, only to change its course later and restart the process. This leaves a series of easily identified layers, separated by periods of no deposits. Big Eddy was formed in a similar way. For some 14,000 years, the Sac River has gently flooded, covering over this site with thick, well stratified, alluvial silt (Bush 2006). This detailed stratigraphy has preserve ...

Cache River (Arkansas)
The Cache River is a tributary of the White River, 213 mi (343 km) long, in northeastern Arkansas in the United States. Its headwaters also drain a small portion of southeastern Missouri. Via the White River, the Cache is part of the Mississippi River watershed, placing the river and surrounding watershed in the Arkansas Delta. Ecology The river supports 53 mammalian species, over 200 bird species, and nearly 50 species of reptiles and amphibians. The refuge is also the most important wintering area for mallard ducks and other migratory waterfowl on the continent. As a result, low-lying areas in the vicinity of the river's lower course are a popular destination for duck hunters. This is also where the ivory-billed woodpecker was recently speculated to have been sighted (after it was believed to be extinct for 60 years). The watershed also contains the largest remaining tract of contiguous bottomland hardwood forest found in North America. Because of these combination o ...

Burlington Limestone
The Burlington Limestone is a geologic formation in Missouri, Iowa and the Midwest region. It preserves fossils dating back to the Mississippian subperiod. Physical properties Burlington Limestone is unusually course-grained, crystalline, crinoidal limestone. Its texture is sufficiently distinctive and persistent to permit recognition of the formation commonly on this basis alone. The Burlington Limestone is made of almost entirely on the remains of various fossils, by far the most important of which are crinoids. Some portions of the Burlington, however, are not so evidently crinoidal, as for example, the so-called "white ledge" quarried in the northeastern part of Missouri. Natural occurrence Burlington Limestone is present in nearly all major Mississippian outcrop regions in Missouri. It is known from Iowa to northwestern Arkansas and from western Illinois to western Kansas. It is present throughout Missouri, except in the Ozark uplift, where it has been removed by eros ...

Stone Tool
A stone tool is, in the most general sense, any tool made either partially or entirely out of stone. Although stone tool-dependent societies and cultures still exist today, most stone tools are associated with prehistoric (particularly Stone Age) cultures that have become extinct. Archaeologists often study such prehistoric societies, and refer to the study of stone tools as lithic analysis. Ethnoarchaeology has been a valuable research field in order to further the understanding and cultural implications of stone tool use and manufacture. Stone has been used to make a wide variety of different tools throughout history, including arrowheads, spearheads, hand axes, and querns. Stone tools may be made of either ground stone or knapped stone, the latter fashioned by a flintknapper. Knapped stone tools are made from cryptocrystalline materials such as chert or flint, radiolarite, chalcedony, obsidian, basalt, and quartzite via a process known as lithic reduction. ...

Hematite
Hematite (), also spelled as haematite, is a common iron oxide compound with the formula, Fe2O3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of . It has the same crystal structure as corundum () and ilmenite (). With this it forms a complete solid solution at temperatures above . Hematite naturally occurs in black to steel or silver-gray, brown to reddish-brown, or red colors. It is mined as an important ore mineral of iron. It is electrically conductive. Hematite varieties include ''kidney ore'', ''martite'' (pseudomorphs after magnetite), ''iron rose'' and ''specularite'' ( specular hematite). While these forms vary, they all have a rust-red streak. Hematite is not only harder than pure iron, but also much more brittle. Maghemite is a polymorph of hematite (γ-) with the same chemical formula, but with a spinel structure like magnetite. Large deposits of hematite are fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metate
A metate (or mealing stone) is a type or variety of quern, a ground stone tool used for processing grain and seeds. In traditional Mesoamerican cultures, metates are typically used by women who would grind nixtamalized maize and other organic materials during food preparation (e.g., making tortillas). Similar artifacts have been found in other regions, such as the sil-batta in Bihar and Jharkhand, India as well as other grinding stones in China. Design and use While varying in specific morphology, metates are typically made of a large stone with a smooth depression or bowl worn into the upper surface. Materials are ground on the metate using a smooth hand-held stone known as a ''mano'' or ''metlapil''. This action consists of a horizontal grinding motion that differs from the vertical crushing motion used in a mortar and pestle. The depth of the bowl varies, though they are typically not deeper than those of a mortar; deeper metate bowls indicate either a longer period of us ...

Chert
Chert () is a hard, fine-grained sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO2). Chert is characteristically of biological origin, but may also occur inorganically as a chemical precipitate or a diagenetic replacement, as in petrified wood. Chert is typically composed of the petrified remains of siliceous ooze, the biogenic sediment that covers large areas of the deep ocean floor, and which contains the silicon skeletal remains of diatoms, silicoflagellates, and radiolarians. Precambrian cherts are notable for the presence of fossil cyanobacteria. In addition to microfossils, chert occasionally contains macrofossils. However, some chert is devoid of any fossils. Chert varies greatly in color (from white to black), but most often manifests as gray, brown, grayish brown and light green to rusty redW.L. Roberts, T.J. Campbell, G.R. Rapp Jr., "Encyclopedia of Mineralogy, Second Edition", 1990. R.S. Mitc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Archaic Period In Southeastern North America
In the classification of the archaeological cultures of North America, the Archaic period in North America, taken to last from around 8000 to 1000 BC in the sequence of North American pre-Columbian cultural stages, is a period defined by the ''archaic stage'' of cultural development. The Archaic stage is characterized by subsistence economies supported through the exploitation of nuts, seeds, and shellfish. As its ending is defined by the adoption of sedentary farming, this date can vary significantly across the Americas. The rest of the Americas also have an Archaic Period. Classifications This classification system was first proposed by Gordon Willey and Philip Phillips in the widely accepted 1958 book ''Method and Theory in American Archaeology''. In the organization of the system, the Archaic period followed the Lithic stage and is superseded by the Formative stage. # The Lithic stage # The Archaic stage # The Formative stage # The Classic stage # The Post-Classic sta ...

Hopewell Tradition
The Hopewell tradition, also called the Hopewell culture and Hopewellian exchange, describes a network of precontact Native American cultures that flourished in settlements along rivers in the northeastern and midwestern Eastern Woodlands from 100 BCE to 500 CE, in the Middle Woodland period. The Hopewell tradition was not a single culture or society but a widely dispersed set of populations connected by a common network of trade routes. At its greatest extent, the Hopewell exchange system ran from the northern shores of Lake Ontario south to the Crystal River Indian Mounds in modern-day Florida. Within this area, societies exchanged goods and ideas, with the highest amount of activity along waterways, which were the main transportation routes. Peoples within the Hopewell exchange system received materials from all over the territory of what now comprises the mainland United States. Most of the items traded were exotic materials; they were delivered to peoples living in the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodland Period
In the classification of archaeological cultures of North America, the Woodland period of North American pre-Columbian cultures spanned a period from roughly 1000 BCE to European contact in the eastern part of North America, with some archaeologists distinguishing the Mississippian period, from 1000 CE to European contact as a separate period. The term "Woodland Period" was introduced in the 1930s as a generic term for prehistoric sites falling between the Archaic hunter-gatherers and the agriculturalist Mississippian cultures. The Eastern Woodlands cultural region covers what is now eastern Canada south of the Subarctic region, the Eastern United States, along to the Gulf of Mexico. This period is variously considered a developmental stage, a time period, a suite of technological adaptations or "traits", and a "family tree" of cultures related to earlier Archaic cultures. It can be characterized as a chronological and cultural manifestation without any massive changes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
