Red Ocher People
The Red Ocher people were an indigenous people of North America. A series of archaeological sites located in the Upper Great Lakes, the Greater Illinois River Valley, and the Ohio River Valley in the American Midwest have been discovered to be a Red Ocher burial complex, dating from 1000 BC to 400 BC, the Terminal Archaic – Early Woodland period. Characterized as shallow burials located in sandy ridges along river valleys, covered in red ochre or hydrated iron oxide (FeH3O), they contain diagnostic artifacts that include caches of flint points, turkey-tails, and various forms of worked copper. Turkey-tails are large flint blades of a distinct type. It is believed that Red Ocher people spoke an ancestral form of the Algonquian languages. Red ochre has a long history of use in North America; as early as the Folsom tradition during the Paleo-Indian period, certain localities in New Mexico and Wyoming were being mined for the substance.Tankersley, Kenneth B., et al.

Great Lakes
The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes in the mid-east region of North America that connect to the Atlantic Ocean via the Saint Lawrence River. There are five lakes, which are Lake Superior, Superior, Lake Michigan, Michigan, Lake Huron, Huron, Lake Erie, Erie, and Lake Ontario, Ontario and are in general on or near the Canada–United States border. Hydrologically, lakes Lake Michigan–Huron, Michigan and Huron are a single body joined at the Straits of Mackinac. The Great Lakes Waterway enables modern travel and shipping by water among the lakes. The Great Lakes are the largest group of freshwater lakes on Earth by total area and are second-largest by total volume, containing 21% of the world's surface fresh water by volume. The total surface is , and the total volume (measured at the low water datum) is , slightly less than the volume of Lake Baikal (, 22–23% of the world's surface fresh water ...

Illinois River
The Illinois River ( mia, Inoka Siipiiwi) is a principal tributary of the Mississippi River and is approximately long. Located in the U.S. state of Illinois, it has a drainage basin of . The Illinois River begins at the confluence of the Des Plaines and Kankakee rivers in the Chicago metropolitan area, and it generally flows to the southwest across Illinois, until it empties into the Mississippi near Grafton, Illinois. Its drainage basin extends into southeastern Wisconsin, northwestern Indiana, and a very small area of southwestern Michigan in addition to central Illinois. Along it's shores are several ports, including Peoria, Illinois. The river was important among Native Americans and early French traders as the principal water route connecting the Great Lakes with the Mississippi. The French colonial settlements along these rivers formed the heart of the area known as the Illinois Country in the 17th and 18th centuries. After the construction of the Illinois and Mich ...

Carbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calc ...

Folsom Tradition
The Folsom Complex is a Paleo-Indian archaeological culture that occupied much of central North America from c. 8500 BCE to c. 4000 BCE. The term was first used in 1927 by Jesse Dade Figgins, director of the Colorado Museum of Natural History. Numerous Paleoindian cultures occupied North America, with some restricted to the Great Plains and Great Lakes of the modern United States of America and Canada as well as adjacent areas to the west and south west. The Folsom Tradition was characterised by use of Folsom points as projectile tips and activities known from kill sites where slaughter and butchering of bison took place and Folsom tools were left behind. Some kill sites exhibit evidence of up to 50 bison being killed, although the Folsom diet apparently included mountain sheep, marmots, deer and cottontail rabbit as well. The Folsom Hanson Site in Wyoming also revealed areas of hardstanding, which indicate possible dwellings. The type site is Folsom site, near Folsom, New ...

Algonquian Languages
The Algonquian languages ( or ; also Algonkian) are a subfamily of Indigenous languages of the Americas, indigenous American languages that include most languages in the Algic languages, Algic language family. The name of the Algonquian language family is distinguished from the orthographically similar Algonquin language, Algonquin dialect of the Indigenous Ojibwe language (Chippewa), which is a senior member of the Algonquian language family. The term ''Algonquin'' has been suggested to derive from the Maliseet word (), "they are our relatives/allies". A number of Algonquian languages are considered extinct languages by the modern linguistic definition. Algonquian peoples, Speakers of Algonquian languages stretch from the east coast of North America to the Rocky Mountains. The proto-language from which all of the languages of the family descend, Proto-Algonquian language, Proto-Algonquian, was spoken around 2,500 to 3,000 years ago. There is no scholarly consensus about wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Flint
Flint, occasionally flintstone, is a sedimentary cryptocrystalline form of the mineral quartz, categorized as the variety of chert that occurs in chalk or marly limestone. Flint was widely used historically to make stone tools and start fires. It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones.''The Flints from Portsdown Hill'' Inside the nodule, flint is usually dark grey, black, green, white or brown in colour, and often has a glassy or waxy appearance. A thin layer on the outside of the nodules is usually different in colour, typically white and rough in texture. The nodules can often be found along s and |
Iron Oxide
Iron oxides are chemical compounds composed of iron and oxygen. Several iron oxides are recognized. All are black magnetic solids. Often they are non-stoichiometric. Oxyhydroxides are a related class of compounds, perhaps the best known of which is rust. Iron oxides and oxyhydroxides are widespread in nature and play an important role in many geological and biological processes. They are used as iron ores, pigments, catalysts, and in thermite, and occur in hemoglobin. Iron oxides are inexpensive and durable pigments in paints, coatings and colored concretes. Colors commonly available are in the "earthy" end of the yellow/orange/red/brown/black range. When used as a food coloring, it has E number E172. Stoichiometries Iron oxides feature as ferrous ( Fe(II)) or ferric ( Fe(III)) or both. They adopt octahedral or tetrahedral coordination geometry. Only a few oxides are significant at the earth's surface, particularly wüstite, magnetite, and hematite. * Oxides of FeII ...

Red Ochre
Ochre ( ; , ), or ocher in American English, is a natural clay earth pigment, a mixture of ferric oxide and varying amounts of clay and sand. It ranges in colour from yellow to deep orange or brown. It is also the name of the colours produced by this pigment, especially a light brownish-yellow. A variant of ochre containing a large amount of hematite, or dehydrated iron oxide, has a reddish tint known as "red ochre" (or, in some dialects, ruddle). The word ochre also describes clays coloured with iron oxide derived during the extraction of tin and copper. Earth pigments Ochre is a family of earth pigments, which includes yellow ochre, red ochre, purple ochre, sienna, and umber. The major ingredient of all the ochres is iron(III) oxide-hydroxide, known as limonite, which gives them a yellow colour. * Yellow ochre, , is a hydrated iron hydroxide (limonite) also called gold ochre. * Red ochre, , takes its reddish colour from the mineral hematite, which is an anhydrous iron oxi ...

Woodland Period
In the classification of :category:Archaeological cultures of North America, archaeological cultures of North America, the Woodland period of North American pre-Columbian cultures spanned a period from roughly 1000 Common Era, 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, prehistoric sites falling between the Archaic period in the Americas, 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. ...
