Fort Sedgwick

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

Fort Sedgwick, also known as Post at Julesburg, Camp Rankin, and Fort Rankin was a U.S. military post from 1864 to 1871, in Sedgwick County, Colorado. There are two historical markers for the former post. The town was named for Fort Sedgwick, which was named after John Sedgwick, who was a major general in the Union Army during the American Civil War.

Fort Sedgwick started with soldiers before it had settlers — the frontier's usual order of operations.

The on-the-ground condition of Fort Sedgwick 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 Fort Sedgwick 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.

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.
