El Cóporo and Tunal Grande settlement work

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

INAH describes activity across different parts of the landscape, so prominent high buildings cannot stand for all residents. The interpretation discusses adobe and plant-based construction alongside stone. Preservation affects which kinds of labor remain visible.

Upland and lowland settlement-work context First millennium CE and early second-millennium transition; phase ranges qualified Building materials, rooms, slopes and regional comparisons Ocampo, Guanajuato (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.
Overview

Tools, water, households, and regional worlds

Desert, peninsular, Pacific, highland, and Bajío connections

Ocampo, Guanajuato is modern orientation, not an ancient capital or boundary. Different settlement zones and building materials indicate varied work, not an unchanging government or a single people.

Political organization and community scale

Different settlement zones and building materials indicate varied work, not an unchanging government or a single people. Tunal Grande is a later regional name, not an ancient self-designation; El Cóporo's Purépecha-derived name does not establish all ancient residents' identity.

Colonial 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. 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.

Settlement beyond the summit INAH describes activity across different parts of the landscape, so prominent high buildings cannot stand for all residents.

Historical sequence

A concise, sourced timeline

These milestones are orientation points, not a complete history.

  1. Settlement activity

    Institutional ranges describe a regional sequence rather than one exact founding event.

    [S1]

  2. Principal investment

    The portal places a prominent interval here while other summaries use broader ranges.

    [S2]

  3. Changing activity

    A proposed settlement decline cannot prove the extinction or replacement of a people.

    [S2]

  4. Tunal Grande label

    The later regional name is not retroactive evidence of an ancient political border.
