This brief starts where responsible research should: with the source description of “Stateline, Idaho” as small city in Kootenai County, Idaho, United States, bordering on Spokane County, Washington. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as small city in Kootenai County, Idaho, United States, bordering on Spokane County, Washington. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jul 27, 2025. The linked authority identifier is Q1510838. The first chronological checks are 2020, 1947 and 2010.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
