Pinneo

Colorado's high-country ghost towns sit at altitudes that would give a flatlander nosebleeds — silver camps killed by an 1893 vote in Washington.

Pinneo is a ghost town in Washington County, in the U.S. state of Colorado. The community is classified as a populated place. A post office called Pinneo was established in 1883, and remained in operation until 1931. The community was named after B. F. Pinneo, a local law enforcement agent.

The on-the-ground condition of Pinneo 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 Pinneo 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 Pinneo is roughly 40.2094, -103.4386 — 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.
