St. Catherines Island
St. Catherines Island is a sea island on the coast of the U.S. state of Georgia, 42 miles (80 km) south of Savannah in Liberty County. The island, located between St. Catherine's Sound and Sapelo Sound, is ten miles (16 km) long and from one to three miles (5 km) wide. It covers approximately 22,265 acres, with about half of the acreage being salt marsh, while the remaining acreage is wooded. There are fine beaches on the northeast and south sides. The island is owned by the Saint Catherines Island Foundation and is not open to the public, apart from the beach below the mean high water line. Physical geography Although often called a barrier island, St. Catherines Island is one of the sea islands found along the Atlantic coast of the southeastern United States between the mouth of the Santee River in South Carolina and the mouth of the St. Johns River in northeastern Florida. While barrier islands typically are long ridges of sand constantly shifting under the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Artesian Aquifer
An artesian aquifer is a confined aquifer containing groundwater under positive pressure. An artesian aquifer has trapped water, surrounded by layers of impermeable rock or clay, which apply positive pressure to the water contained within the aquifer. If a well were to be sunk into an artesian aquifer, water in the well-pipe would rise to a height corresponding to the point where hydrostatic equilibrium is reached. A well drilled into such an aquifer is called an ''artesian well''. If water reaches the ground surface under the natural pressure of the aquifer, the well is termed a ''flowing artesian well''. Fossil water aquifers can also be artesian if they are under sufficient pressure from the surrounding rocks, similar to how many newly tapped oil wells are pressurized. From the previous statement, it can be inferred that not all aquifers are artesian (i.e., water table aquifers occur where the groundwater level at the top of the aquifer is at equilibrium with atmospher ...

Venison
Venison originally meant the meat of a game animal but now refers primarily to the meat of antlered ungulates such as elk or deer (or antelope in South Africa). Venison can be used to refer to any part of the animal, so long as it is edible, including the internal organs. Venison, much like beef or pork, is categorized into specific cuts, including roast, sirloin, and ribs. Etymology The word derives from the Latin ''venari'', meaning "to hunt or pursue". This term entered the English language through Norman French ''venaison'' in the 11th century, following the Norman conquest of England and the establishment of Royal Forests. Definition ''Venison'' originally described meat of any game animal killed by hunting and was applied to any animal from the families ''Cervidae'' (true deer), ''Leporidae'' (rabbits and hares), ''Suidae'' (wild boar) and certain species of the genus ''Capra'' (goats and ibex). In southern Africa, the word ''venison'' refers to the meat of antelope, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 precipitation (chemistry), chemical precipitate or a diagenesis, 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, Dictyochales, silicoflagellates, and radiolarians. Precambrian cherts are notable for the presence of fossil cyanobacteria. In addition to Micropaleontology, 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.

Savannah River Point
The Savannah River point (also, Savannah River Stemmed or Appalachian Stemmed) is a Late Archaic period projectile point commonly found in the southeastern United States. The point is large, triangular, and has a square stem. It is relatively thin for its size. Savannah River points are 44 to 170 mm long, 35 to 70 mm wide, and 7 to 12 mm thick. A Small Savannah River point, a Cattle Run variant, an Otarre Stemmed variant, and a short-stemmed variant have also been described. The type was first described based on finds at Stallings Island. The points were formed by percussion flaking and finished using pressure flaking In archaeology, in particular of the Stone Age, lithic reduction is the process of fashioning stones or rocks from their natural state into tools or weapons by removing some parts.

Temper (pottery)
A temper is a non-plastic material added to clay to prevent shrinkage and cracking during drying and firing of vessels made from the clay. Tempers may include: *Bone; *Chaff; *Charcoal; *Ground schist; *Wood ash; * Grit; *Sand or crushed sandstone; *Crushed limestone; *Crushed igneous rocks, such as volcanic rock, feldspar, or mica; *Grog; *Plant fiber; *Horse manure (dried and sifted); *Crushed mollusc shells (including fossilized) (see Shell tempering in the Mississippian culture); and *Freshwater sponge spicules. Some clays used to make pottery do not require the addition of tempers. Pure kaolin clay Kaolinite ( ) is a clay mineral, with the chemical composition Al2 Si2 O5( OH)4.

Posthole
In archaeology a posthole or post-hole is a cut feature used to hold a surface timber or stone. They are usually much deeper than they are wide; however, truncation may not make this apparent. Although the remains of the timber may survive, most postholes are mainly recognisable as circular patches of darker earth when viewed in plan. Archaeologists can use their presence to plot the layout of former structures, as the holes may define its corners and sides. Construction using postholes is known as earthfast or post in ground construction. Parts of a posthole Although a very common structure, and one of the most basic found in archaeology, correct interpretation relies on being able to tell the often subtle differences that distinguish the parts of the posthole. The components of an archaeological posthole are listed in order of creation and, in ideal circumstances, the reverse order of their excavation. ;Posthole cut This is the cut that formed the hole. It is cut from the ground ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Before Present
Before Present (BP) years, or "years before present", is a time scale used mainly in archaeology, geology and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1 January 1950 as the commencement date (epoch) of the age scale. The abbreviation "BP" has been interpreted retrospectively as "Before Physics", which refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, which scientists must now account for. In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation RCYBP stands for the explicit "radio carbon years before present". Usage The BP scale is sometimes used for dates established by means other than radiocarbon dating, such as stratigraphy. This usage differs from t ...

Stallings Island
Stallings Island is an archeological site with shell mounds, located in the Savannah River near Augusta, Georgia. The site is the namesake for the Stallings culture of the Late Archaic period and for Stallings fiber- tempered pottery, the oldest known pottery in North America. The site was declared a National Historic Landmark in 1961.Note: A National Register of Historic Places Inventory-Nomination document should be available upon request from the National Park Service for this site (perhaps redacted to remove location information), but it appears not to be available on-line from thNPS Focus search site Stallings Island pottery found in coastal Georgia was formerly called St. Simons pottery, but is now recognized as Stallings Island. Description and history Stallings Island is located upriver of Augusta, in an area known as the Ninety-Nine Islands, just downriver of the mouth of Stevens Creek.
