Goodall Focus
The Goodall focus was a Hopewellian culture from the Middle Woodland period peoples that occupied Western Michigan and northern Indiana from around 200 BCE to 500 CE. Extensive trade networks existed at this time, particularly among the many local cultural expressions of the Hopewell communities. The Goodall pattern stretched from the southern tip of Lake Michigan, east across northern Indiana, to the Ohio border, then northward, covering central Michigan, almost reaching to Saginaw Bay on the east and Grand Traverse Bay to the north. The culture is named for the Goodall site in northwest Indiana.Hopewell Archeology: The Newsletter of Hopewell Archeology in the Ohio River Valley; 4.

Great Lakes
The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes spanning the Canada–United States border. The five lakes are Lake Superior, Superior, Lake Michigan, Michigan, Lake Huron, Huron, Lake Erie, Erie, and Lake Ontario, Ontario (though hydrologically, Lake Michigan–Huron, Michigan and Huron are a single body of water, joined at the Straits of Mackinac). The Great Lakes Waterway enables modern travel and shipping by water among the lakes. The lakes connect to the Atlantic Ocean via the Saint Lawrence River, and to the Mississippi River basin through the Illinois Waterway. The Great Lakes are the largest group of freshwater lakes on Earth by total area and the second-largest by total volume. They contain 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 f ...

Grand Traverse Bay
Grand Traverse Bay ( ) is an arm of Lake Michigan, located along the west coast of the Lower Peninsula of Michigan. The bay is separated from the rest of Lake Michigan by the Leelanau Peninsula. The bay is some long, ranges from wide, and up to deep in spots. It is the second-largest bay of Lake Michigan, behind Green Bay. Grand Traverse Bay is further divided into an East Arm and West Arm by the Old Mission Peninsula. At the head of both arms of the bay is Traverse City, the largest city in Northern Michigan. The area surrounding the bay is renowned for its fruit production, especially for cherries and viticulture. The bay is located within parts of the Michigan counties of Antrim, Charlevoix, Grand Traverse, and Leelanau. Etymology Grand Traverse Bay earned its name from 18th-century French voyageurs who made ', or "the long crossing", across the mouth of bay. The area was owned by the French, followed by Great Britain as the Province of Quebec. After 1776, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand River (Michigan)
The Grand River (Ottawa: ''owashtanong'', "Far-Flowing Water") is a river in the Lower Peninsula of the U.S. state of Michigan. The longest river in Michigan, the Grand River rises in Hillsdale County, and flows in a generally northwesterly direction to its mouth at Lake Michigan in the city of Grand Haven. The river flows through a number of cities, including Jackson, Lansing, Ionia, and Grand Rapids. The river was famous for its mile-long, 300-yard-wide, and 10-to-15-foot-tall rapids, for which the city of Grand Rapids was named. These rapids were submerged following the construction of numerous dams, starting in 1835, and flooding of areas behind the dams. The river has not had any rapids for nearly a century. Course The headwaters of the Grand River begin from natural springs in Somerset Township in Hillsdale County near the boundary with Liberty Township in Jackson County. From there, the river flows through Jackson, Ingham, Eaton, Clinton, Ionia, Kent, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Obsidian
Obsidian ( ) is a naturally occurring volcanic glass formed when lava extrusive rock, extruded from a volcano cools rapidly with minimal crystal growth. It is an igneous rock. Produced from felsic lava, obsidian is rich in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. It is commonly found within the margins of rhyolite, rhyolitic lava flows known as obsidian flows. These flows have a high content of silicon dioxide, silica, giving them a high viscosity. The high viscosity inhibits the atomic diffusion, diffusion of atoms through the lava, which inhibits the first step (nucleation) in the formation of mineral crystals. Together with rapid cooling, this results in a natural glass forming from the lava. Obsidian is hard, Brittleness, brittle, and amorphous; it therefore Fracture (mineralogy)#Conchoidal fracture, fractures with sharp edges. In the past, it was used to manufacture cutting and piercing tools, and it has been used experimentally as s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middens
A midden is an old dump for domestic waste. It may consist of animal bones, human excrement, botanical material, mollusc shells, potsherds, lithics (especially debitage), and other artifacts and ecofacts associated with past human occupation. These features provide a useful resource for archaeologists who wish to study the diets and habits of past societies. Middens with damp, anaerobic conditions can even preserve organic remains in deposits as the debris of daily life are tossed on the pile. Each individual toss will contribute a different mix of materials depending upon the activity associated with that particular toss. During the course of deposition sedimentary material is deposited as well. Different mechanisms, from wind and water to animal digs, create a matrix which can also be analysed to provide seasonal and climatic information. In some middens individual dumps of material can be discerned and analysed. Shells A shell midden or shell mound is an archaeolog ...

Columella (gastropod)
The columella (meaning "little column") or (in older texts) pillar is a central anatomical feature of a coiled snail shell, a gastropod shell. The columella is often only clearly visible as a structure when the shell is broken, sliced in half vertically, or viewed as an X-ray image. The columella runs from the apex of the shell to the midpoint of the undersurface of the shell, or the tip of the siphonal canal in those shells which have a siphonal canal. If a snail shell is visualized as a cone of shelly material which is wrapped around a central axis, then the columella more or less coincides spatially with the central axis of the shell. In the case of shells that have an umbilicus (mollusc), umbilicus, the columella is a hollow structure. The columella of some groups of gastropod shells can have a number of plications or folds (the columellar fold, plaits or plicae), which are usually visible when looking to the inner lip into the Aperture (mollusc), aperture of the shell. These ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Stone
Bird stones are prehistoric, abstract roughly bird-shaped stone carvings made by Native Americans. The artifacts were a common inclusion in graves and thought to have ceremonial importance. They first appeared in the middle Archaic period around 5,000 years ago and continued into the early Woodland period to about 2,500 years before present. The exact purpose of these artifacts is not known, but most have a small hole drilled at the base of the neck and another at the aft end, presumably for mounting. Some theories suggest they were part of an atlatl (a short rod to hurl spears), in addition to their ceremonial uses. A new theory recently arising from an amateur archaeologist focused on Native American fiber processing, is the bird stone was a tool used for mat-making and weaving. Many stones have been found near waterways and swamp areas where reeds grow, these areas being where materials for mat-making were collected and processed. The holes in the base were potentially use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iron Oxide
An iron oxide is a chemical compound composed of iron and oxygen. Several iron oxides are recognized. Often they are non-stoichiometric. Ferric 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 ** FeO: ir ...

Ochre
Ochre ( ; , ), iron 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. A range of other minerals may also be included in the mixture:Krivovichev V.

Disturbance (archaeology)
A disturbance is any change to an archaeological site due to events which occurred after the site was laid down. Disturbances may be caused by natural events or human activity, and may result in loss of archaeological value. In some cases, it can be difficult to distinguish between features caused by human activity in the period of interest, and features caused by later human activity or natural processes. Causes Natural causes The soil science, soil scientist Francis D. Hole identified nine natural processes resulting in soil disturbance, including the movements of animals and plants (known as bioturbation, and including burrowing, root growth and tree uprooting, treefalls); freezing and thawing; movement under gravity (including earthflow and rockslides); swelling and shrinking of clays; the actions of wind and water; the growth and dissolution of salt crystals; and movement caused by earthquakes. Different sites are subject to different degrees, combinations, and interactio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
