Alma

California wrote the book on ghost towns, from Gold Rush tent cities to Owens Valley farm towns the aqueduct dried up.

Alma is an 1891-built scow schooner, which is now preserved as a National Historic Landmark at the San Francisco Maritime National Historical Park in San Francisco, California.

The on-the-ground condition of Alma 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.

Here's the honest truth: access to Alma is unverified. We couldn't confirm whether the site sits on public land, private property, or something in between — so verify land ownership and local rules before visiting, and respect private property at all times. The mapped point for Alma is roughly 37.8104, -122.4228 — use it as a starting point and cross-reference a current topographic map before leaving pavement.

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.
