How the setting appeared

Settlements and causeways occupied riverbanks, seasonally flooded plains and forest mosaics containing orchards, fields and anthropogenic dark earth.

How people lived

Large and small societies followed distinct political systems; epidemic and colonial disruption should not be mistaken for an untouched or empty forest.

Historical geography

A dated anchor, not an exact border

The local map uses modern coastlines only for orientation. The marker identifies this record's geographic anchor, not the full reach of a community or polity.

Map geometry loads only when requested. Modern outlines are orientation only; historical geography and identities changed through time.
