Archeological Site 4-SK-4
Archeological Site 4-SK-4, in Tulelake, California, near Macdoel, California, is a stratified archeological site that was a hunter-gatherer village on the west shores of the Lower Klamath Lake. The site is located in the heart of the Klamath Basin wetlands, west of Indian Tom Lake. It has also been known as Nightfire Island and as Sheepy Island. Modern Modocs have called the island ''Shapasheni'' (Shapash /xpni), meaning "where the sun and moon live", or "home of the sun and the moon. Prehistorically, it served as a village camp on a man-made mound in the wetlands and as a ceremonial site.Howe, 8-9 The site shows evidence of human occupancy from the peak of the Hypsithermal era, approximately 7,000 years ago. Archeologist have unearthed three villages one on top of the other through the centuries. Obsidian arrowheads are frequent finds, whose varieties include Northern Sided Notched, Elko type corner notched, and Gunther type points. Excavations and sampling started in 1966 by K ...

Tulelake, California
Tulelake ( ) is a city in northeastern Siskiyou County, California, United States. The town is named after nearby Tule Lake. Its population is 902 as of the 2020 census, down from 1,010 from the 2010 census. Tulelake peace officers are authorized by state law, along with cooperation of the state of Oregon, to serve as and be recognized as peace officers within Malin, Oregon, along with the inverse being true for peace officers employed within Malin, wherein they are recognized as peace officers within Tulelake by the California Penal Code. History The first public auction of Tulelake land parcels took place on April 15, 1931. Over 100 lots were sold for prices ranging from $65 to $350. In 1937, the city was incorporated. Today there are over 400 housing units. Two World War II internment camps were located near Tulelake.

Lake
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sweat Lodge
A sweat lodge is a low profile hut, typically dome-shaped or oblong, and made with natural materials. The structure is the ''lodge'', and the ceremony performed within the structure may be called by some cultures a purification ceremony or simply a sweat. Traditionally the structure is simple, constructed of saplings covered with blankets and sometimes animal skins. Originally, it was only used by some of the Indigenous peoples of the Americas, notably the Plains Indians, but with the rise of pan-Indianism, numerous nations that did not originally have the sweat lodge ceremony have adopted it. This has been controversial. In all cases, the sweat is intended as a spiritual ceremony – it is for prayer and healing, and the ceremony is only to be led by elders who know the associated language, songs, traditions, and safety protocols. Otherwise, the ceremony can be dangerous if performed improperly. Sweat lodges have also been imitated by some non-natives in North America and ...

Great Basin
The Great Basin is the largest area of contiguous endorheic basin, endorheic watersheds, those with no outlets, in North America. It spans nearly all of Nevada, much of Utah, and portions of California, Idaho, Oregon, Wyoming, and Baja California. It is noted for both its arid climate and the basin and range topography that varies from the North American low point at Badwater Basin in Death Valley to the highest point of the contiguous United States, less than away at the summit of Mount Whitney. The region spans several physical geography, physiographic divisions, biomes, ecoregions, and deserts. Definition The term "Great Basin" is applied to hydrography, hydrographic, ecology, biological, floristic province, floristic, physiographic, topography, topographic, and Ethnography, ethnographic geographic areas. The name was originally coined by John C. Frémont, who, based on information gleaned from Joseph R. Walker as well as his own travels, recognized the hydrographic nature o ...

Spall
Spall are fragments of a material that are broken off a larger solid body. It can be produced by a variety of mechanisms, including as a result of projectile impact, corrosion, weathering, cavitation, or excessive rolling pressure (as in a ball bearing). Spalling and spallation both describe the process of surface failure in which spall is shed. The terms ''spall'', ''spalling'', and ''spallation'' have been adopted by particle physicists; in neutron scattering instruments, neutrons are generated by bombarding a uranium (or other) target with a stream of atoms. The neutrons that are ejected from the target are known as "spall". Mechanical spalling Mechanical spalling occurs at high stress contact points, for example, in a ball bearing. Spalling occurs in preference to brinelling where the maximal shear stress occurs not at the surface, but just below, shearing the spall off. One of the simplest forms of mechanical spalling is plate impact, in which two waves of compression ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Knapping
Knapping is the shaping of flint, chert, obsidian, or other conchoidal fracturing stone through the process of lithic reduction to manufacture stone tools, strikers for flintlock firearms, or to produce flat-faced stones for building or facing walls, and flushwork decoration. The original Germanic term ''knopp'' meant to strike, shape, or work, so it could theoretically have referred equally well to making statues or dice. Modern usage is more specific, referring almost exclusively to the hand-tool pressure-flaking process pictured. It is distinguished from the more general verb "chip" (to break up into small pieces, or unintentionally break off a piece of something) and is different from "carve" (removing only part of a face), and "cleave" (breaking along a natural plane). Method Flintknapping or knapping is done in a variety of ways depending on the purpose of the final product. For stone tools and flintlock strikers, chert is worked using a fabricator such as a hammersto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithic Reduction
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. It has been intensely studied and many archaeological industries are identified almost entirely by the lithic analysis of the precise style of their tools and the chaîne opératoire of the reduction techniques they used. Normally the starting point is the selection of a piece of tool stone that has been detached by natural geological processes, and is an appropriate size and shape. In some cases solid rock or larger boulders may be quarried and broken into suitable smaller pieces, and in others the starting point may be a piece of the debitage, a flake removed from a previous operation to make a larger tool. The selected piece is called the lithic core (also known as the "objective piece"). A basic distinction is that between flaked or knapped stone, the main subject here, and ground stone object ...

Cascade Point
A Cascade point is a projectile point associated with the Cascade phase, an ancient culture of Native Americans that settled in the Pacific Northwest that existed from 9000 or 10000 BC until about 5500 BC. The Cascade (Bipointed) point is typically narrow, lanceolate leaf shaped, with either a pointed or rounded base. There are also two other variants, one with a shallow concave base and the other with a sharply contracting basal margin. Cascade points are generally regarded as poor temporal markers because they are found in early, middle, and even late Holocene contexts. It is unclear whether this broad timespan is a function of prolonged use of the point form, later groups recycling discarded artifacts, or a combination of both. The spatial and temporal distribution of foliate points in the northern Great Basin and present new data derived from work at a stratified rockshelter in Oregon's Warner Valley have been reviewed. Foliate projectile points have been uncovered there tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spear-thrower
A spear-thrower, spear-throwing lever or ''atlatl'' (pronounced or ; Nahuatl ''ahtlatl'' ) is a tool that uses leverage to achieve greater velocity in dart or javelin-throwing, and includes a bearing surface which allows the user to store energy during the throw. It may consist of a shaft with a cup or a spur at the end that supports and propels the butt of the spear. It's usually about as long as the user's arm or forearm. The user holds the spear-thrower in one hand, gripping near the end farthest from the cup. The user puts the butt end of the spear, or dart, in the cup, or grabs the spur with the end of the spear. The spear is much longer than the thrower. The user holds the spear parallel to the spear-thrower and going in the other direction. The user can hold the spear, with the index and thumb, with the same hand as the thrower, with the other fingers. The user reaches back with the spear pointed at the target. Then they make an overhand throwing motion with the thrower ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mortar And Pestle
Mortar and pestle is a set of two simple tools used from the Stone Age to the present day to prepare ingredients or substances by crushing and grinding them into a fine paste or powder in the kitchen, laboratory, and pharmacy. The ''mortar'' () is characteristically a bowl, typically made of hard wood, metal, ceramic, or hard stone such as granite. The ''pestle'' (, also ) is a blunt, club-shaped object. The substance to be ground, which may be wet or dry, is placed in the mortar where the pestle is pounded, pressed, and rotated into the substance until the desired texture is achieved. Mortars and pestles have been used in cooking since prehistory; today they are typically associated with the profession of pharmacy due to their historical use in preparing medicines. They are used in chemistry settings for pulverizing small amounts of chemicals; in arts and cosmetics for pulverizing pigments, binders, and other substances; in ceramics for making grog; in masonry and in other typ ...

Duripan
A duripan is a diagnostic soil horizon of the USDA soil taxonomy that is cemented by illuvial silica into a subsurface hardpan. Similar to a fragipan, Petrocalcic Horizon and petrogypsic horizon, it is firmly cemented and restricts soil management. In soil descriptions, they are most often denoted by the symbol Bqm. The closest equivalent in the Canadian system of soil classification is called a duric horizon, although it does not mean exactly the same thing as a duripan in the United States. They form almost exclusively in arid or Mediterranean climates, and can be as hard as concrete, which makes plowing very difficult or impossible. Soils that include duripans are generally used for grazing or wildlife habitat, and are seldom cultivated. Characteristics The required characteristics for a duripan, according to the "Keys to USDA soil taxonomy, Tenth Edition, 2006" are: # The pan is cemented or indurated in more than 50 percent of the volume of some horizon; ''and'' # The pan ...
