Why this record matters

The linked authority identifier is Q6338058. Authority coordinates are 36.008, -115.006. 3 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.
