The Seneca Nation of Indians identifies five contemporary territories in Western New York: Cattaraugus, Allegany, Oil Spring, Buffalo Creek, and Niagara Falls. This atlas introduces a source-grounded dossier for each without treating all five land histories or legal regimes as interchangeable.
01 / Territory inventory
The Nation's published descriptions and transportation plan identify the geographic setting of each territory. A description of location is not a survey, deed, federal status decision, or parcel-level jurisdiction conclusion.
Erie · Chautauqua · Cattaraugus counties
Follow the Creek corridor from Lake Erie toward Gowanda; examine 1802 land descriptions, the 1842 settlement, municipal interfaces and transportation.
Research lens: Treaty-protected territory and adjacent local government relationships.
Open territory dossier →N-01 · N-02 · H-02Cattaraugus County
Examine Salamanca, Nation land tenure, rights-of-way and the Kinzua Dam impacts within the broader Allegany territory.
Research lens: Territorial leasing, transportation, and infrastructure.
Open territory dossier →N-01 · N-03 · L-01Allegany · Cattaraugus county line
Investigate a historically documented spring and modern territory description, with particular attention to mapped accuracy.
Research lens: Small-territory land description and survey controls.
Open territory dossier →N-01 · N-04 · F-01Erie County
Connect the existing Buffalo parcel files and compact research to modern acquisitions without confusing them with historic Buffalo Creek.
Research lens: Modern holdings distinguished from historic reservation.
Open territory dossier →N-01 · F-01 · Existing IT-R02Niagara County
Review federal acquisition records and related Nation/state/municipal instruments without extending conclusions to other properties.
Research lens: Modern acquisition, gaming and urban land-use questions.

| Territory | Location reference | Leading research question | Map verification |
|---|---|---|---|
| Cattaraugus | Cattaraugus Creek · Irving to Gowanda | Treaty-protected territory and adjacent local government relationships | Boundary verification pending |
| Allegany | Allegheny River · Salamanca | Territorial leasing, transportation, and infrastructure | Boundary verification pending |
| Oil Spring | Cuba Lake vicinity | Small-territory land description and survey controls | Boundary verification pending |
| Buffalo Creek | City of Buffalo | Modern holdings distinguished from historic reservation | Boundary verification pending |
| Niagara Falls | City of Niagara Falls | Modern acquisition, gaming and urban land-use questions | Boundary verification pending |
Place descriptions are regional references only. The atlas does not assert that entire cities, roads, or counties lie within territory boundaries.
03 / Evidence-based cartography
Loading the Western New York topographic reference map…
Checking published Seneca Nation GIS territory features, with U.S. Census reference fallback. No legal boundary is certified.
Layer provenance: Preferred polygons come directly from the Seneca Nation Geographic Information Services public Territory Boundaries layer (SNI-GIS). If its GIS query is unavailable or does not return a named match, the viewer separately attempts U.S. Census TIGERweb mapping geography (January 1, 2026). Both are drawn over USGS The National Map. Visible attribution identifies which layer actually loaded. Neither GIS layer is a certified legal survey, title opinion or conclusive status/jurisdiction decision. Initial viewport centers are regional reference points, not claimed survey coordinates. External map providers receive tile/GIS requests when the viewer opens. Opening an interactive map may disclose the visitor's IP address, browser information and map-view request to those providers. The publisher privacy notice explains associated practices. The map is not a legal title, survey or jurisdiction decision, and a source polygon must not be applied to an individual parcel without tract-level documentary verification.
Begin with the Nation's transportation-plan exhibits and Maps & Boundaries Department. Our existing Erie County GIS viewer remains available for specific Buffalo tax-parcel polygons only. The GIS viewer displays the Nation's public territory-boundary reference when available, with a separately labeled Census fallback. Neither reference substitutes for a controlling survey, deed, or federal-status instrument; historic outlines remain withheld.
Source-labeled territory names, dated planning references, linked geographic dossiers, county/regional descriptors, and qualified context.
Verified source identificationSurvey-quality boundary geometry, tract-to-SBL matches, changes in shoreline or watercourses, overlapping tenure interests, or present federal status classifications without controlling instruments.
Requires geospatial & legal crosswalk04 / Temporal separation
The historical Buffalo Creek Reservation should not be conflated with modern Seneca lands in Buffalo. Historical Seneca geography includes former reserved areas and broad traditional homelands; Tonawanda is a distinct federally recognized Nation today.
Trace the 1794, 1797, 1802, 1838 and 1842 evidence chain; keep disputed interpretations, approximate historic maps and modern legal boundaries visibly separate.
05 / Source register
These are public source pointers for the expanded research program, not a claim that every treaty, survey, deed, and current law has been exhaustively reviewed. The existing 131-record Phase 1 evidence snapshot remains separately dated and unchanged.
