Methods in Cultural and Archaeological Research
Archaeological Research Methods
Fieldwork Surveying and Site Preparation:
The foundational step in archaeological field research is surveying the target geographic area.
Archaeologists systematically locate, map, and document visible surface and subsurface features, including historical trails, ancient roadways, and house pits.
Prior to excavation, archaeologists establish a precise grid system over the site to maintain exact spatial control and provenance for all discoveries.
Every cultural artifact and natural feature encountered during excavation is meticulously recorded in place.
Archaeological context is essential for interpretation and is divided into primary context (the original, undisturbed location of an object's deposit) and secondary context (a location where an object has been moved or disturbed by natural or human activities post-deposition).
Site Example: The Vindolanda dig site in England represents an extensive archaeological excavation that has yielded thousands of historical artifacts left behind by Roman occupiers between 85 CE and 370 CE.
Relative Dating and Stratigraphy:
Relative dating determines the chronological sequence of artifacts and human cultural contexts without assigning an exact calendar date.
Principle of Superposition (Law of Superposition): In an undisturbed geological or cultural sequence, deeper soil or rock layers (strata) are older than the layers deposited above them.
Stratigraphic Layer Analysis: Archaeologists analyze distinct strata to infer relative age:
Stratum A (Uppermost / Youngest): Represents modern ground surface deposits containing modern items such as a car license plate ("DEL 328"), an aluminum can, and a plastic bottle.
Stratum B: Underlies Stratum A and contains historical items such as a horseshoe, a steel can, and a glass bottle.
Stratum C: Contains earlier historic or protohistoric items like a shell button and a bullet.
Stratum D: Composed of a distinct sand and gravel layer.
Stratum E (Deepest / Oldest): Contains ancient cultural material including a basket fragment, pottery fragments, and a stone arrow point. Under superposition, pottery in Stratum E is established as older than shell buttons in Stratum C, while surface items remain the most recent.
Absolute (Chronometric) Dating Methods:
Chronometric or absolute dating methods determine specific calendar ages or age ranges for artifacts and organic samples.
These techniques rely directly on physical or chemical analyses of organic or inorganic properties.
Four primary absolute dating methods utilized in archaeological research include:
Radiocarbon () dating.
Dendrochronology (tree-ring dating).
Thermoluminescence dating.
Potassium-argon () dating.
Conservation and Naturalism
The 19th-Century Conservation Movement and Naturalism:
The formal conservation movement emerged during the 19th century.
A central component of early conservation was naturalism, which involved systematically collecting biological specimens and cultural items for display in natural history museums.
Early institutional collections gathered extensive assortments of animal specimens, Native American baskets, and Indigenous artistic objects.
Zooarchaeological Comparative Collections: Faunal collections (such as the osteological specimens maintained at the Wildlife Forensics Lab in Ashland, Oregon) serve as essential comparative resources for zooarchaeologists identifying animal remains from archaeological sites.
Salvage Anthropology:
Initiated in the late 19th century under the erroneous assumption that Indigenous populations, particularly Native Americans, were rapidly going extinct.
Researchers sought to collect material culture, languages, and rituals before these societies vanished.
Methods of acquiring cultural items varied widely, ranging from legitimate purchases to coercion and direct theft.
A large portion of salvage anthropology research was commissioned and funded by the Bureau of American Ethnology.
Anthropological Advocacy: Leo J. Frachtenberg was a prominent salvage-era anthropologist who actively used his position and research to advocate for and assist the Indigenous communities he studied.
Museum Archives and Cultural Recovery:
The vast majority of material objects, audio recordings, and field manuscripts collected during the salvage era were deposited in museum vaults and university archives.
Due to intensive, rapid collecting practices, field materials were frequently archived without being analyzed or published, remaining in storage long after researchers changed projects or passed away.
Linguistic anthropologist Henry Zenk conducted extensive archival research on these historical materials to reconstruct the languages and cultural traditions of western Oregon. Zenk's research directly assisted the Chinook people in recovering lost aspects of their language and history.
Profile: Albert Gatschet:
Albert Gatschet (1832–1907) was a Swiss-American philologist and ethnologist who pioneered the scientific and systematic study of Native American languages.
He conducted comparative linguistic analyses across sixteen southeastern tribal vocabularies, with an intensive focus on the Timucua language of northern Florida.
He was officially commissioned by the Bureau of American Ethnology to document Algonquian languages across the United States and Canada.
Interpretation and Indigenous Voice:
Interpretation plays a pivotal role in constructing narratives about human history and cultural artifacts.
Historically, museum displays reflected restricted, outsider interpretations that often misrepresented Indigenous traditions.
Contemporary museums actively collaborate with Native community members and knowledge holders to re-interpret collections accurately.
Incorporating Indigenous perspectives actively corrects long-standing historical misconceptions regarding the functional use, spiritual meaning, and social context of cultural items.
Ethnography and Ethnology
Foundations of Ethnography and Ethnology:
Ethnography: The primary qualitative research methodology used by cultural anthropologists to produce a detailed, descriptive account of a specific culture, community, or society based on direct field research.
Ethnology: The cross-cultural comparison and analysis of different societal groups to identify patterns, similarities, and differences.
Ethnological analysis remains an essential analytical tool across multiple subfields, including anthropological linguistics, archaeology, and biological anthropology.
Franz Boas (1858–1942) established rigorous empirical standards for ethnographic field research, forming the operational foundation of modern anthropology.
Perspectives and Bias in Ethnographic Research:
Anthropologists must recognize and control for potential subjective bias when collecting and analyzing field data.
Ethnocentrism: The practice of viewing, judging, or evaluating another culture through the implicit biases, values, and standards of one's own cultural background.
Emic Perspective: An insider perspective that attempts to understand and describe cultural practices, beliefs, and values from the internal viewpoint of the community members themselves.
Feminist Anthropology and Plural Perspectives:
Early anthropological literature was disproportionately authored by male scholars, resulting in ethnographies that focused heavily on male activities while ignoring or marginalizing women's roles.
In 1929, Margaret Mead achieved national and discipline-wide prominence with the publication of her ground-breaking ethnographic study Coming of Age in Samoa.
Feminist Anthropology: A theoretical framework that emerged to critique and correct historical white, male-dominated biases in research.
Feminist approaches explicitly integrate gender analysis, highlighting women's contributions, power structures, and subjective experiences in society.
Participant Observation and Interviewing
Participant Observation Methodologies:
Participant observation requires researchers to directly engage in the daily routines, rituals, events, and community activities of a host culture over an extended duration.
Researchers maintain exhaustive records through multiple mediums, including physical field notebooks, computer files, digital audio recordings, photography, and film.
Ethnographers also collect representative physical objects and material culture with community consent.
Interview Techniques and Field Dynamics:
Interviews are conducted in environments where informants feel comfortable and secure.
Interviews range in structure from informal, open-ended conversations to semi-structured and highly structured question sets.
Informants provide critical emic insights into societal norms, family histories, and cultural meanings.
Explicit legal and ethical permission must be obtained prior to recording interviews or utilizing audio/video data in published academic works.
Ethnographic Case Study: Ethnographer Stuart Butler spent two months walking alongside Josphat Mako, a Maasai man, traveling between Maasai villages in Kenya to study traditional customs alongside contemporary socio-economic challenges.
Ethical Oversight and Institutional Protocols:
Sociocultural anthropologists must receive formal research approval from an Institutional Review Board (IRB) prior to initiating fieldwork.
Researchers must adhere strictly to local community protocols, customary laws, and ethical standards established by the study population.
Long-Term Field Research: Long-term immersion is a core methodological standard, enabling researchers to establish deep trust, mutual respect, and ongoing collaborative relationships across many years.
Critique of Academic Exploitation: Indigenous scholar Vine Deloria Jr. famously challenged the discipline by questioning whether 19th- and 20th-century anthropologists delivered any tangible benefits to the tribal communities they studied.
Intellectual Property and Ownership: Modern ethical guidelines state that cultural knowledge, oral histories, and ethnographic content remain the intellectual property of the research participants rather than the field researcher.
Collaborative Publication: The text Chinuk Wawa, produced by The Chinuk Wawa Dictionary Project, explicitly attributes linguistic anthropologist Henry Zenk as a compiler rather than the sole owner of the language data.
IRB Informed Consent: Formal consent documentation mandates transparent communication regarding project goals, risks, and benefits, ensuring participants freely select their exact level of participation and anonymity.
Quantitative and Qualitative Analysis
Quantitative vs. Qualitative Research:
Quantitative Data: Numeric, countable, or measurable data used to calculate statistical probabilities, demographic trends, and resource patterns.
Qualitative Data: Subjective, descriptive data focused on the contextual analysis of human language, social behaviors, symbolic systems, ritual practices, and interpersonal dynamics.
Data Triangulation: The methodological practice of combining quantitative and qualitative data sources to cross-validate findings and build robust, holistic research conclusions.
Data Modeling and Geospatial Mapping:
Anthropologists construct conceptual and physical models to visualize complex data relationships and communicate findings.
Cartographic maps are fundamental theoretical and empirical models.
Archaeology relies heavily on Global Positioning System (GPS) technologies to record exact spatial coordinates, mapping site features and artifact distributions to build three-dimensional spatial models.
The Scientific Method in Anthropology:
Anthropology operates as an empirical science utilizing systematic inquiry.
Researchers adhere strictly to the scientific method:
Formulate a defined research question based on existing literature.
Construct testable, falsifiable hypotheses.
Gather empirical field data through structured methodologies.
Analyze data to evaluate and test the hypothesis.
Retest conclusions through independent verification.
All scientific hypotheses remain open to re-evaluation, revision, or rejection as new empirical evidence is discovered.
Archives, Three-Dimensional Collections, and Ownership
Archival Collections and Management:
Archival repositories house published literature, recreated manuscripts, original historical documents, and field records under specialized climate controls to prevent degradation.
To protect rare materials, archives enforce strict access protocols and research guidelines.
The primary step in archival research is reviewing finding aids, indexes, and catalog records to locate relevant manuscript groups.
Three-Dimensional Artifact Collections:
Physical artifact collections (such as basketry, textiles, and ceramics) are stored separately from paper manuscript archives.
Storage facilities require strict microclimate management, maintaining precise ambient temperature and relative humidity levels to slow material decay.
Artifacts are organized systematically to maximize accessibility for continuing research.
Historical Conservation Errors: During the early 20th century, museum curators routinely treated organic collections with toxic chemical pesticides (such as DDT) and coated objects in synthetic lacquers. These destructive methods caused chemical damage, requiring ongoing remediation efforts.
Organic Artifact Example: A pair of woven yucca sandals—crafted from the tough leaves of the perennial yucca plant—was collected from the Southern Paiute people in 1875 and is housed at Harvard University's Peabody Museum.
Ownership, Provenance, and Repatriation:
Historical Ownership Assumptions: Historically, institutions and anthropologists claimed absolute ownership over collected artifacts, publishing rights, and decision-making power regarding collections transfer.
Contemporary Challenges: Indigenous populations and descendant communities challenge institutional ownership of their cultural heritage and human remains.
Repatriation: The legal and ethical process of returning ancestral human remains, sacred objects, funerary objects, and items of cultural patrimony to their native communities.
Key Legislative Frameworks:
National Historic Preservation Act (NHPA) of 1966: Federal legislation requiring federal agencies to evaluate, preserve, and protect historic sites and cultural properties across the United States.
Native American Graves Protection and Repatriation Act (NAGPRA) of 1990: Landmark federal law establishing a legal process for Native American tribes and Native Hawaiian organizations to claim human remains and sacred cultural items held by federally funded museums and institutions. Prior to 1990, Indigenous communities had no legal mechanism to reclaim millions of ancestral remains gathered since the 19th century.
Provenance: Detailed historical and geographical documentation establishing the precise origin and chain of custody for an artifact. A lack of specific provenance prevents repatriation, as broad regional descriptions make it difficult to establish legal cultural affiliation with a specific modern tribe.
Tribal Archival Reclamation Case Studies:
Coquille Indian Tribe Recognition: In 1989, the Coquille Indian Tribe of Oregon successfully utilized historical manuscripts retrieved from the Smithsonian Institution to restore their federal tribal recognition. Key effort organizer George Wasson Jr. led the collection of these critical records.
Southwest Oregon Research Project (SWORP): A collaborative project organized by the Coquille Indian Tribe, University of Oregon anthropologists, and Indigenous students. The project copied and repatriated over 150,000 pages of historical documents concerning western Oregon tribes from the Smithsonian Institution and National Archives, establishing a centralized archive at the University of Oregon.
Summers Collection Case Study:
Assembled by Reverend Robert Summers (an Episcopalian minister residing in McMinnville, Oregon), the collection contained over 600 West Coast Native objects, including 300 collected directly from the nearby Grand Ronde Reservation.
In the 1990s, the Confederated Tribes of the Grand Ronde Community identified the collection held at the British Museum in London.
Because no international repatriation laws exist, the Grand Ronde community engaged in formal diplomacy, negotiating an agreement in 2018 to secure a long-term loan of 16 key objects for public display at the Chachalu Museum and Cultural Center in Grand Ronde, Oregon.
