Cathlapotle: lower Columbia plank-house communities

Reviewed community and place names are preserved where supported; no otherwise unknown ancient self-designation is invented.

Ames and Sobel combine radiocarbon, objects and documentary comparison to identify the town and its chronology. The field report describes several large house contexts and alluvial deposits, not a single synchronous plan of every household.

River-town household and research context Approximately 1450–1700 CE focus; later occupation and reconstruction distinguished Radiocarbon chronology, house deposits, archaeological comparison and attributed later journals Ridgefield, Washington, United States (orientation only): approximate public-town or distant institutional orientation, not an excavation, burial, sacred-site, private compound or vulnerable-deposit location; never a territorial, ethnic, linguistic, cultural, political, religious, sovereignty, fishing, farming, water-rights or route boundary. The orientation may be far from the archaeological context. No access, collecting or travel permission is implied.
Overview

Coastal households, river connections, and the evidence

Coastal, island, estuary, and river connections

Ridgefield, Washington, United States is a modern orientation, not an ancient capital or boundary. Multiple households and a river town require evidence-specific political interpretation, not a single Chinookan state.

Political organization and community scale

Multiple households and a river town require evidence-specific political interpretation, not a single Chinookan state. The 2005 plankhouse is a modern reconstruction; later explorers' estimates are attributed testimony, not a precontact population census.

Later transformation, living heritage, and modern reception

Living communities and heritage institutions retain their own authority; this atlas cannot establish identity, ancestry, descent, recognition or membership. Chinookan is used in its historical and linguistic context, not as one universal government or a DNA category. Later colonial, research, reconstruction and stewardship events are dated separately from the main archaeological context.

Multiple dating sources Ames and Sobel combine radiocarbon, objects and documentary comparison to identify the town and its chronology.

Historical sequence

A concise, sourced timeline

These milestones are orientation points, not a complete history.

  1. Town occupation

    The dating study places occupation by this period, with possible movement from a nearby earlier location.

    [S1]

  2. Explorers' journals

    The dating study evaluates external written observations alongside material evidence; they do not represent every resident.

    [S1]

  3. Field investigations

    The cumulative report describes excavations and sampling within a larger river landscape.

    [S2]

  4. Plankhouse opens

    A newly constructed building interprets earlier architecture; it is not a surviving precontact house.

    [S3]
Culture and language

Foodways, craft, household work, and tended landscapes
