Source-derived summary

Lac de Retournemer is a lake in Xonrupt, Vosges, France. At an elevation of 776 m, its surface area is 0.05 km2. It has an area of 5 hectares, or about 12.3 acres.

Editorial summary

Begin with the source’s own compact description: “Lac de Retournemer” is glacial lake. The dossier treats that line as a proposition to test through Retournemer, glacial and lake, not as a finished interpretation.

Editorial reviewA valuable geographic starting point for tracing changing names, boundaries, uses and administrative responsibility. The current 33-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. For this dossier, Retournemer, glacial and lake is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “glacial lake” 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.

Evidence profile

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 Aug 12, 2026. The linked authority identifier is Q1553818. Authority coordinates are 48.057, 6.983. 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.
