Nevado de Acay
mountain in Argentina
Nevado de Acay is a 5,950-metre-high (19,520 ft) mountain in Argentina. It is a volcanic intrusion that formed during the Miocene and was later exposed. The intrusion is formed by monzonite and is associated with a fault system that also connects to neighbouring volcanoes.
While not presently glaciated, it contains a seasonal snowpack and is the source of several streams and rivers, including the Rio Salado. A number of archeological sites have been found on Nevado de Acay and mining activity occurred there until recent times.

Why this record matters
The phrase “mountain in Argentina” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
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 Oct 24, 2025. The linked authority identifier is Q21848132. VIAF identifies the subject as 234325842. Authority coordinates are -24.416, -66.161. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
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.
