Contemporary Nation territories
Five geographic territories identified in current Seneca Nation and federal source materials: Allegany, Cattaraugus, Oil Spring, Buffalo Creek and Niagara Falls.

Four different concepts must not collapse into one map
Historical treaty-reserved tracts
Reservation and tract descriptions as they appeared in different instruments. Boundaries must be dated, transcribed and georeferenced without silently extending them into the present.
Treaty library →Broader ancestral homeland
Historical settlement and cultural geography in the Genesee Valley and Finger Lakes, a historical subject distinct from legally established contemporary territorial boundaries.
Nation historical account ↗Related but distinct Nations
The Tonawanda Band of Seneca Indians is a separate federally recognized Nation. Historical treaty records referencing Tonawanda do not establish Seneca Nation of Indians governance over Tonawanda today.

Historical instruments to reconstruct
| Date | Document / event | Geographical research task | Record status |
|---|---|---|---|
| 1794 | Treaty of Canandaigua | Identify treaty commitments and contemporaneous territorial references; preserve precise text and parties. | Primary transcription review |
| 1797 | Treaty of Big Tree and land arrangements | Trace conveyances and reservations, source parties and schedules, and distinct tract labels. | Land schedule crosswalk |
| 1802 | Buffalo Creek instruments | Read separately the two June 30, 1802 Seneca treaty catalog records and reconstruct how exchange language affected Cattaraugus geography. | Document-level reconciliation |
| 1838 | Buffalo Creek treaty and transaction | Identify proposed disposals and the reservations affected; separate initial terms from later settlement and legal effect. | Contested-history review |
| 1842 | Buffalo Creek settlement with the Seneca | Reconcile the disposition of Buffalo Creek against Allegany and Cattaraugus, affected parties and subsequent title consequences. | Treaty text available |
| 1857 | Tonawanda Seneca treaty | Preserve distinct Nation status and examine historical relationship with the preceding 1838/1842 record. | Separate-Nation dossier |
The National Archives treaty catalog lists two separate June 30, 1802 Seneca records, a May 20, 1842 Seneca record, and a November 5, 1857 Tonawanda record. Chronology labels here are discovery aids rather than interpretive conclusions about uninspected originals.
03 / Buffalo comparison
Historical Buffalo Creek is not the modern Buffalo Creek Territory
A historical reservation described in nineteenth-century instruments and modern Seneca Nation lands associated with Buffalo gaming-era acquisitions have different legal-document chains. A modern GIS tax lot cannot establish continuity between them by geographical proximity alone.
Historical Buffalo Creek
Separate historical land descriptions, sale and settlement records, treaty effects, former boundaries and later development of the City of Buffalo.
Historical treaty instruments →Modern Buffalo Creek
Specific modern land acquisitions, federal determinations, Nation/state arrangements and parcel-status questions; review on their own evidence.

Before we publish a historical boundary layer
- Identify the document. Preserve instrument date, parties, authoritative edition and full legal description.
- Resolve geometry source. Obtain surveyed exhibits or georeferenced historical cartography with publication permissions.
- Preserve uncertainty. Document map georeferencing error and any watercourse, shoreline, road or nomenclature changes.
- Mark time and meaning. A historic polygon must display an effective or source date and its evidence classification; it must not impersonate a modern cadastral or sovereign boundary.
- Separate authorities. Nation property interests, individual possessory interests, tax-map boundaries, and federally recognized status require distinct overlays.
Historical boundary overlays not yet published
We will not manufacture former reservation outlines from modern county lines or period illustrations. The National Archives catalog and the Nation's historical account are available while georeferencing and legal-description review are prepared.
