GLOSSARY OF FREQUENTLY USED TERMS
The following list contains the definitions of some of the technical terms utilized in, or important to, this website.
Altithermal: A warm, dry climate period during the mid-Holocene, dated circa 8000-2900 B.P. (Moratto 1984:585).
Antler Flaker (Tiner): An implement made from an antler tip or tine and used in pressure flaking (Jennings 1974:373).
Archaeological Resources: All evidences of past human occupations which can be used to reconstruct the lifeways of past peoples. These include sites, artifacts, environmental and all other relevant information and the contexts in which they occur. Archaeological resources are found in prehistoric and aboriginal sites, as well as historic Indian and European areas of occupation and activity (McGimsey and Davis 1977:109).
Archaeology: The scientific discipline responsible for recovering, analyzing, interpreting, and explaining the unwritten portion of the historic and prehistoric past (McGimsey and Davis 1977:109).
Artifact: Any product of human cultural activity; more specifically, any tools, weapons, artworks, etc. found in archaeological contexts (Moratto 1984:585).
Asphaltum: A black to brown petroleum- or bitumen-based semi-solid mineral pitch used as an adhesive for hafting purposes and for applying decorations on objects (after Jennings 1974:373).
Assemblage: The complete inventory of artifacts from a single, defined archaeological unit (such as a stratum or component) (Moratto 1984:585).
Awl: A bone or stone tool tapered to a point and used to pierce holes or make decorations (Thomas 1979:456).
B.P.: Before the present. As used in radiocarbon and other archaeological dating, the present is defined as A.D. 1950.
Background Studies: Any of a wide variety of investigations to support primary archaeological research. Such studies might include vegetation studies, pollen or soil analyses, reconstruction of past environments, linguistic reconstructions, or other detailed analyses.
Base Camp: A site occupied by several families or more on either a year round or seasonal basis. Identified archaeologically by primary and secondary tools (that is, tools used in the manufacture of other tools) and a variety of other artifacts, as well as floral and faunal remains from subsistence activities. Characterized by extensive scatters and quantities of debris such as potsherds, fire-cracked rock, whole and broken flaked stone tools, chipping waste, charred bone, milling tools, house structures, hearths, rock rings, and sometimes rock art or burials. A well-developed midden is usually a component of this type.
Bedrock Mortar: A mortar cup in a bedrock outcrop (Moratto 1984:586). See "Mortar."
Biface: Any stone artifact worked (flaked) on both the obverse and reverse faces. Most projectile points are bifaces (Moratto 1984:586).
Bioturbation: The disturbance created by burrowing rodents, insects, roots, etc.
Bipolar Flaking: A distinctive type of percussion flaking in which a blow is struck against the top of a pebble or core resting on a hard "anvil" stone; this causes simultaneous flaking from both ends and results in flakes and flake scars peculiar to the method (Moratto 1984:586).
BRM: An abbreviation for Bedrock Mortar.
Catchment: The resource area around an archaeological site which is within convenient walking distance (Thomas 1979:457).
Centimeter: See "Metric Measurements."
Charmstone: According to Moratto, a charmstone is "an elongate ground- and often polished-stone artifact, normally 5-20 cm in length, fashioned in a spindle, ovoid, phallic, plumb bob, or other shape; may be grooved or plain, perforate or imperforate; often found with burials. The prominence of charmstones in marshy regions has been noted. Their function as hunting charms, bolas stones, shamanistic gear, and so forth, is uncertain" (Moratto 1984:587).

Chopper: A large, often crude pebble, cobble, or core tool percussion-flaked to form an axe-like cutting edge along part of its margin; used for diverse chopping and cleaving work (Moratto 1984:587).
Complex: A patterned grouping of similar artifact assemblages from two or more sites, presumed to represent an archaeological culture (Moratto 1984:588).
Component: A site or stratum within a site representing the activities of one cultural group during a relatively brief interval of time. (An exception would be a component resulting from interaction of two or more groups at a single site.) Similar or related components within a locality or region comprise a phase (Moratto 1984:588).
Conservation: An approach to archaeology based on a philosophy stressing the protection, preservation, and/or managed use of the cultural resources base for future generations. Protection of representative sites and preservation of data through scientific study are major aspects of this approach. It differs from salvage archaeology which stressed the immediate recovery of material from threatened sites (McGimsey and Davis 1977:109-110).
Core: A stone from which flakes have been removed to make implements. A prepared core is one which has been purposefully worked so that the shape of flakes or blades can be controlled (Jennings 1974:375).
Cultural Affiliation: The known, projected, or hypothesized cultural, ethnic, or tribal group (e.g., Hopewellian, Mississippian, Puebloan, Eskimo, Apache, historic Anglo, etc.) with which archaeological remains may be identified on the basis of careful scientific study (McGimsey and Davis 1977:110).
Cultural Resource Management (CRM): The development and maintenance of programs designed to protect, preserve, and scientifically study and manage cultural resources (including evidences of prehistoric, protohistoric, historic, and recent remains) and the natural resources that figured significantly in cultural systems.... The goal of such programs should be the conservation of cultural values and the maximum effective conservation and utilization of these resources for the public good (McGimsey and Davis 1977:110).
Cultural Resources: Districts, sites, structures, and objects and evidence of some importance to a culture, a subculture, or a community for scientific, traditional, religious, and other reasons. These resources and relevant environmental data are important for describing and reconstructing past lifeways, for interpreting human behavior, and for predicting future courses of cultural development (McGimsey and Davis 1977:110).
Culture History: The archaeological sequence of cultural activity through time, within a defined geographic space or relating to a particular group (Moratto 1984:588).

Dialect: The variety of a language spoken by all members of a speech community; languages may include many, mutually intelligible dialects (Moratto 1984:589).
Diffusion: The transmission of concepts or artifacts from one cultural setting to another without population movement; the principal mechanism by which a culture acquires new traits (Moratto 1984:589).
Earspool: A spool-shaped stone ornament worn in the ear lobe.
Ecofacts: The nonartifactual remains found in archaeological sites such as seeds, bones, and plant pollen (Thomas 1979:459).
Ecotone: The juncture between two biotic communities (e.g., grassland and forest). Ecotones offer more biotic diversity than "pure" communities at the interface--the "edge effect." Ecotones were ideal places for aboriginal settlement because they afforded optimum resource exploitation (Moratto 1984:589).
Ethnographic Resources: All evidences of identifiable ethnic lifeways dating to historic or protohistoric periods which may be used for describing, reconstructing, and interpreting cultural systems. These include sites, artifacts, ethnographic records, documentary records, informants, environmental data, and all other relevant information. Ethnographic resources are cultural resources and may be considered archaeological resources when they provide needed information relative to the scientific study of archaeological resources (McGimsey and Davis 1977:110).
Ethnography: The direct anthropological study of living human groups or the study of recent, historically documented groups (Moratto 1984:589).
Ethnohistorical Resources: Data on historic and contemporary societies. These include documentary sources and the study of material culture from these groups which are relevant to the study area (McGimsey and Davis 1977:110).
Excavation: The scientifically controlled recovery of subsurface materials and information from an archaeological site. Recovery techniques are designed to produce maximum knowledge about the utilization of the site, its relation to other sites and the natural environment, and its significance in the maintenance of the cultural system. Recovery techniques may include the use of heavy equipment (e.g., backhoe, etc.) and specialized instruments (pollen coring tools, etc.) (McGimsey and Davis 1977:110).

Flotation: The use of fluid suspension to recover tiny plant and bone fragments from archaeological sites (Thomas 1979:461).
Gram: See "Metric Measurements."
Ground Stone: Stone artifacts manufactured by pecking and abrading techniques. Usually included in this category are grinding and pounding implements such as the mano, metate, mortar, and pestle, as well as pipes and statuary pieces (Jennings 1974:376).

Historic Resources: All evidences of human occupations that date from historic (i.e., recorded history) periods. These resources include documentary data (i.e., written records, archival material, photographs, maps, etc.), sites, artifacts, environmental data and all other relevant information. Historic resources are cultural resources and may be considered archaeological resources when archaeological work is involved in their identification and interpretation (McGimsey and Davis 1977:111).
Holocene (Recent): The post-Pleistocene geologic epoch characterized by fluctuating but generally moderate climates and modern faunal assemblages; dated circa 11,000 B.P. to the present (Moratto 1984:590).
Impact, Direct: The effects an action will have on environmental resources as a direct and immediate result of construction or development. This includes destruction of archaeological sites and their environment by earth-moving, plowing, flooding, or building construction. These effects are not limited to the localities modified by the project but also include features such as access roads, construction crew camps, etc., which are ancillary to the project (McGimsey and Davis 1977:111).
Impact, Indirect: The effects on the environment which are not an immediate and direct result of an action, but which would probably not occur without it. Indirect impact is the extent to which a project or action exposes resources, either within or adjacent to the development, to such adverse effects as accelerated erosion, intensified agriculture, construction of private homes or commercial buildings, road-building, increased vandalism, modification of ecological relationships, and other disturbances attendant to the project (McGimsey and Davis 1977:111).

Obsidian Hydration Dating: A method for determining the age of obsidian artifacts or débitage by measuring the thickness of a specimen's hydration rim (layer of water penetration) and comparing the rim depth with the established hydration rate for the particular climatic-geographic area (effective hydration temperature) and type of obsidian (Moratto 1984:593). Where no hydration rate has been derived, this technique is used to compare hydration rind values from different pieces.
Ocher: A ferruginous clay or earth ranging from yellow to brown, used as a pigment. Red ocher (hematite) is very often used for ceremonial purposes (Jennings 1974:377). See "Hematite."
Olivella: A genus of marine univalves, found on the North American Pacific Coast and in the Gulf of Mexico, whose shell was widely used as money and for making necklaces (Jennings 1974:377).
Percussion Flaking: The manufacture of stone artifacts by removing flakes with blows struck by a stone, antler or bone "hammer" (Moratto 1984:593).
Pestle: An elongate, often cylindrical stone or wooden artifact used to pulverize food products and other stuff in a mortar (Moratto 1984:593).

Pressure Flaking: The technique of removing flakes from a stone by pressing a blunt, pointed implement of antler or bone against the edge being worked. This method permits greater control over the size and direction of the flakes removed than does percussion flaking (Jennings 1974:378).
Projectile Point: A sharp tip (usually stone) affixed to the business end of a spear, lance, dart, or arrow (Moratto 1984:594).
Projectile Point: A sharp tip (usually stone) affixed to the end of a spear, lance, dart, or arrow (Moratto 1984:594).
Quartzite: A compact, granular rock composed of quartz, used for chipped stone implements (Jennings 1974:378).
Radiocarbon Dating: (Also known as Carbon-14 or C-14 dating.) A method by which a carbon-containing organism or compound may be dated. Radiocarbon is present in the atmosphere in relatively stable, although small, amounts. All living organisms in equilibrium with the atmosphere maintain a small natural concentration of radiocarbon. When the organism dies radiocarbon is no longer replaced, and the initial concentration begins to decrease. By knowing the initial concentration of radiocarbon, the decay rate, and the present amount, an age can be assigned to the specimen (Gillespie 1984).
Regional Information Center: A series of regional facilities originally established by the Society for California Archaeology in conjunction with the California Department of Transportation. The Regional Information Centers are funded by the California Office of Historic Preservation and by users. Within each region, the facilities house survey reports, site records, maps, and other data pertaining to cultural resources and their management. Current professional standards require consultation with the appropriate Regional Information Center(s) for cultural resource management projects.
Rock Art: Inclusive term referring to both pictographs (designs painted on stone surfaces) and petroglyphs (designs pecked or incised into stone surfaces) (Thomas 1979:467).
Saxidomus: The genus of Washington clam.
Scraper: A stone implement used to remove fat from the under side of a skin, to smooth wood, to scrape leather, etc. Different types are described in terms of the shape and/or position of the cutting edge: side scraper, end scraper, snubnosed scraper, thumbnail scraper, scoop scraper, etc. (Jennings 1974:378-379).
Settlement Pattern: The distribution of human populations throughout their habitat (Thomas 1979:468).
Site: Any area or location occupied as a residence or utilized by humans for a sufficient length of time to leave physical remains or traces of occupancy. Such localities are extremely variable in size, and may range from a single hunting camp to an extensive land surface with evidence of numerous settlements and activities (McGimsey and Davis 1977:113).
Soapstone: See "Steatite."
Steatite: Hydrous magnesium silicate, a very soft and easily carved metamorphic rock valued by the Indians as a raw material for bowls, beads, and artwork. Its ability to withstand heat without cracking made steatite an ideal materials for cooking vessels, tobacco pipes, and so forth (Moratto 1984:595).
Stone Boiling: A method of cooking by dropping hot stones or clay balls into a basket or container filled with liquid and/or the substance to be cooked. This method was used when the cooking vessel couldn't be placed directly over the fire (Jennings 1974:379).
Strata: The various layers of human or geological origin which comprise archaeological sites (Thomas 1979:468).
Stratigraphy: An analytical interpretation of the structure produced by deposition of geological and/or cultural sediments into layers or strata (Thomas 1979:469).

Tegula: The genus of turban snails.
Temporary Campsite: A site occupied by a limited number of individuals either seasonally or for short periods. Such a site frequently is characterized by limited activities and specialized tools. Within central California, such sites may result from exploiting specific resources, such as acorns (e.g., camping and processing sites in good collecting areas), seasonal fish runs (e.g., camping and fish processing sites along rivers or streams), or marine resources (e.g., coastal camping and/or gathering sites along the ocean).
Testing/Test Excavation: The preliminary, exploratory and limited excavation of portions of sites or specific features within sites carried out for the purpose of better defining site size (vertically and horizontally), site complexity, chronological span of components at sites, quantity of subsurface materials, state of preservation and other aspects critical to the determination of site significance, problems for investigation, proper research methods, and research time and costs for future studies (McGimsey and Davis 1977:113).
Thermally-altered Rock (also called fire-cracked rock and abbreviated FCR): Rock which has been discolored, cracked or otherwise altered by exposure to fire. This frequently is characteristic of prehistoric occupation sites.
Tivela: The genus of Pismo Clams.
Tradition: A way of life or consistent patterning of technology, subsistence practices, and ecological adaptation which persists through a relatively long interval of time (Moratto 1984:596).
Tribelet: The basic, autonomous, self-governing and independent sociopolitical group in aboriginal California; an aggregation of several villages under the authority of a single chief (Kroeber 1925; Moratto 1984:596).
Trinomial: An archaeological site is usually assigned a trinomial by the Regional Information Center. This consists of the state abbreviation (CA), followed by the county abbreviation (MNT), followed by a number. An example would be CA-MNT-1481. The suffix "H" indicates the resource is historic. The suffix "/H" indicates both historic and prehistoric resources are present.
Uniface: A stone tool that has been flaked only on one side (Thomas 1979:470).
Use wear: The changes or modifications in an artifact resulting from repeated use. Some wear patterns wear are distinctive, and can be associated with specific activities.
Utilized flake: A flake tool which exhibits use wear.
Village: The term "village" refers to a site of previous human occupancy, generally of some size. This term is used in most of the ethnographic reports, but it is almost always undefined; indeed, its usage may vary from author to author. See also "Base Camp."
