La Playa: farming, water, and dated sequences

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

The museum describes an INAH–Arizona project studying early agricultural communities; its research categories do not define a living people. The stratigraphic study separates sediment units from cultural associations. An old sediment age alone cannot date an irrigation feature.

Early farming and water-management context Early Agricultural and later contexts; sampled canals approximately 750–350 BCE and 50–250 CE Sediment stratigraphy, irrigation features and multiple dating techniques Trincheras, Sonora (orientation only): approximate public-town or distant institutional orientation, not an excavation, burial, sacred-site, cave-entrance, private compound or vulnerable-deposit location; never a territorial, ethnic, linguistic, cultural, political, religious, sovereignty, farming, water-rights or route boundary. The orientation may be far from the archaeological context. No access, collecting or travel permission is implied.

Connexions désertiques, péninsulaires, du Pacifique, de hauts plateaux et du Bajío

Trincheras, Sonora is modern orientation, not an ancient capital or boundary. Waterworks imply organized work but cannot establish one authority across all occupation episodes.

Organisation politique et échelle communautaire

Waterworks imply organized work but cannot establish one authority across all occupation episodes. Old sediments do not date every cultural deposit; La Playa canal phases and calibrated samples must remain distinct, without a single-origin farming claim.

Transformation coloniale, patrimoine vivant et réception moderne

Living communities and heritage institutions retain their own authority; this atlas cannot establish identity, ancestry, descent, recognition or membership. Archaeological materials do not identify every ancient speaker. Living language communities, self-designations and membership authority remain distinct. Events after 1600 CE and modern research, conservation and stewardship are dated separately from the main historical context.

Joint research The museum describes an INAH–Arizona project studying early agricultural communities; its research categories do not define a living people.

Séquence historique

Uma cronologia breve e documentada

Ces repères servent d'orientation et ne constituent pas une histoire complète.

  1. Earlier waterwork episode

    The canal study identifies an earlier dated interval, not the start of all regional farming.

    [S3]

  2. Later waterwork episode

    A later interval must not be collapsed into the earlier one.

    [S3]

  3. Different components

    The stratigraphic research distinguishes subsequent cultural material from the early agricultural evidence.

    [S2]

  4. Comparative dating

    The canal publication tests how different dating methods constrain the surviving features.
