Why this belongs in the atlas
Regional names, grape names, and annual reports answer different questions. Read the regional reference alongside the Zinfandel field guide and the Cordon Creek archive to keep those layers connected without collapsing them into one claim.
For source details and known limits, consult the references in the rail. The first release is intentionally useful at a modest scale: it establishes a dependable route through the public record and leaves room for verified additions.
