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 Jul 16, 2026. The linked authority identifier is Q1656920. Authority coordinates are 38.031, -120.414. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
