Why this record matters
The subject matters to the places & architecture register because the source frames it as alpine lake in Custer County, Idaho. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Aug 19, 2026. The linked authority identifier is Q5370459. Authority coordinates are 44.051, -114.610. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. 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.
