Keystone

Montana's ghost towns span gold-rush gulches and the great homestead bust that emptied the Hi-Line.

The Keystone Pipeline System is an oil pipeline system in Canada and the United States, commissioned in 2010 by TransCanada (later TC Energy). It is owned by South Bow, since TC Energy's spin off of its liquids business into a separate publicly traded company, effective October 1, 2024. It runs from the Western Canadian Sedimentary Basin in Alberta to refineries in Illinois and Texas, and also to oil tank farms and an oil pipeline distribution center in Cushing, Oklahoma. TransCanada Keystone Pipeline GP Ltd, abbreviated here as Keystone, operates four phases of the project.

The on-the-ground condition of Keystone 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 Keystone 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 Keystone is roughly 47.2683, -114.9357 — 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.
