The on-the-ground condition of Caledonia is unverified — it's listed here with unknown status. That could mean standing buildings, or an empty field. Go prepared for either, and consider sharing what you find so the record improves.

Nobody has confirmed the access situation, so treat any visit as reconnaissance: verify land ownership first, and be ready to admire from the road.

Ghost-town etiquette is simple: take only photographs. Removing artifacts is illegal on public lands and disrespectful everywhere else — and on federal land it can be a serious offense.
