Cooper's Ferry Site
Cooper's Ferry is an archaeological site along the lower Salmon River (Idaho), Salmon River near the confluence with Rock Creek in the western part of the U.S. state of Idaho, and part of the Lower Salmon River Archeological District. It is south of the town of Cottonwood, Idaho, Cottonwood and upstream from the Snake River. Various lithic and animal remains from the Pleistocene to early Holocene ages have been found there. The site is on traditional Nez Perce land, and known to the tribe as the historical village of Nipéhe. Excavations Initial excavation at the site was conducted by B. Robert Butler in 1961, 1962, and later in 1964. Stemmed projectile points were recovered in a Stratigraphy (archaeology), stratified context; no chronometric dating occurred. In 1997 Loren G. Davis conducted a text excavation finding four stemmed points, in the same horizontal position, and 9 other lithic tools (one large uniface, three blade (archaeology), blades, two lithic cores, two modified ...

Flake Tool
In archaeology, a flake tool is a type of stone tool that was used during the Stone Age that was created by striking a flake from a prepared stone core. People during prehistoric times often preferred these flake tools as compared to other tools because these tools were often easily made, could be made to be extremely sharp & could easily be repaired. Flake tools could be sharpened by retouch to create scrapers or burins. These tools were either made by flaking off small particles of flint or by breaking off a large piece and using that as a tool itself. These tools were able to be made by this "chipping" away effect due to the natural characteristic of stone. Stone is able to break apart when struck near the edge. Flake tools are created through flint knapping, a process of producing stone tools using lithic reduction. Lithic reduction Lithic reduction is the removal of a lithic flake from a larger stone in order to reach the desired tool shape and size. The beginning ston ...

East Wenatchee Clovis Site
The East Wenatchee Clovis Site (also called the Richey-Roberts Clovis Site or the Richey Clovis Cache) is a deposit of prehistoric Clovis points and other implements, dating to roughly 11,000 radiocarbon years before present or about 13,000 calendar years before present, found near the city of East Wenatchee, Washington in 1987. Accidentally discovered in an apple orchard by Mark Mickels, it yielded some of the largest stone Clovis points known to science. After controversy over its excavation, the site was sealed off from further digging from 1992 until 2007. History The site was accidentally uncovered by Mark Mickels and farmworker Moises Aguirre Calzada on May 27, 1987, while installing an irrigation line. His digging unearthed about two dozen stone bifaces, which were at first mistaken for tools left by contemporary Indian tribes. Orchard co-owner Rich Roberts and his wife Joanne later showed the items to local amateur archaeologist Russell S. Congdon, who identified them as C ...

Archaeology Of The Americas
The archaeology of the Americas is the study of the archaeology of the Western Hemisphere, including North America (Mesoamerica), Central America, South America and the Caribbean. This includes the study of pre-historic/Pre-Columbian and historic indigenous American peoples, as well as historical archaeology of more recent eras, including the Trans-Atlantic slave trade and European colonization. Chronology The Pre-Columbian era is the term generally used to encompass all time period subdivisions in the history of the Americas spanning the time from the original settlement of the Americas in the Upper Paleolithic until the European colonization of the Americas during the early modern period. While technically referring to the era before the voyages of Christopher Columbus from AD 1492 to 1504, in practice the term usually includes the history of American indigenous cultures until the 18th or 19th century. In more recent decades, archaeological scholarship has extended to inclu ... [...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] |
Western Stemmed Tradition
The Western Stemmed Tradition (WST) is a Paleoindian archaeological culture known from the Intermountain West of North America, particularly the Great Basin and the Columbian Plateau, spanning from over 13,000 years Before Present (and thus overlapping with the more well-known Clovis culture) to around 8,500 years Before Present. Unlike Clovis and related traditions, the stone projectile points produced by the Western Stemmed Tradition are unfluted (lacking flakes removed at the base). Other types of tool produced by WST peoples include Chipped-stone crescent, stone crescents. The Western Stemmed Tradition has a wide variability in tool morphology, and is divided up into a number of chronologically separated subtypes, including Haskett (~12,600-11,500 years BP), Cougar Mountain (Great Basin, 11,700-9,000 years BP), Lind Coulee (Columbia Plateau, 12,000-11,200 years BP, named after Lind Coulee Archaeological Site) Parman (Great Basin 11,300-9,000 years BP) Silver Lake (Great Basin, 1 ...

Spear Point
In North American archaeological terminology, a projectile point is an object that was hafted to a weapon that was capable of being thrown or projected, such as a javelin, dart, or arrow. They are thus different from weapons presumed to have been kept in the hand, such as knives, spears, axes, hammers, and maces. Stone tools, including projectile points, can survive for long periods, were often lost or discarded, and are relatively plentiful, especially at archaeological sites. They provide useful clues to the human past, including prehistoric trade. A distinctive form of point, identified though lithic analysis of the way it was made, is often a key diagnostic factor in identifying an archaeological industry or culture. Scientific techniques exist to track the specific kinds of rock or minerals that were used to make stone tools in various regions back to their original sources. As well as stone, projectile points were also made of worked wood, bone, antler, horn, or ivory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bureau Of Land Management
The Bureau of Land Management (BLM) is an agency within the United States Department of the Interior responsible for administering federal lands. Headquartered in Washington DC, and with oversight over , it governs one eighth of the country's landmass. President Harry S. Truman created the BLM in 1946 by combining two existing agencies: the General Land Office and the Grazing Service. The agency manages the federal government's nearly of subsurface mineral estate located beneath federal, state and private lands severed from their surface rights by the Homestead Act of 1862. Most BLM public lands are located in these 12 western states: Alaska, Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming. The mission of the BLM is "to sustain the health, diversity, and productivity of the public lands for the use and enjoyment of present and future generations." Originally BLM holdings were described as "land nobody wanted" because home ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radiocarbon 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 ...
