Editorial summary

This brief starts where responsible research should: with the source description of “Phaq'u Tanka” as mountain in Peru. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewMost useful as a place-based finding aid connecting the present description to earlier jurisdictions, maps and built evidence. The current 67-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. The account is most persuasive where Phaq'u, Tanka and mountain can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the places & architecture register because the source frames it as mountain in Peru. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

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 15, 2026. The linked authority identifier is Q19421300. Authority coordinates are -16.629, -70.228. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

Critical limits

A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. 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.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
