Some ghost towns feel like museums. Comet feels like an interruption — a place that stopped mid-sentence. Comet is a ghost town located approximately twenty miles (32 kilometers) south-southwest of Helena, Montana, United States. It is reached by following High Ore Road north from Interstate 15.

Jefferson County holds 3 documented ghost towns, including Elkhorn, Wickes — Comet keeps them company on the map.

The story of Comet

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

Comet is a ghost town located approximately twenty miles (32 kilometers) south-southwest of Helena, Montana, United States. It is reached by following High Ore Road north from Interstate 15. The remains of the town cover about thirty-five acres and consist of an ore hopper, a large ore processing building, several other company buildings, and numerous houses and other private structures. High Ore Creek runs through the center of the property and separates the mine buildings from the town proper.

What you'll find today

Comet survives as partial ruins — standing walls, collapsed roofs, and the bones of a town that once was. Ruin sites can be hazardous: watch for open shafts, unstable masonry, and wildlife sheltering in debris. Bring sturdy boots and photograph from safe distances.

Public access makes Comet one of the easier ghost towns to actually stand in — though "public" in ghost-town country can still mean miles of dirt road, so check recent trip reports first.

Getting there

Comet is publicly accessible — but give the word "accessible" some respect. Out here it can still mean miles of unmaintained dirt road. Check recent trip reports, carry extra water and a spare tire, download offline maps, and let someone know your route.

Good to know

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.

The ground itself demands respect: open mine shafts, collapsing floors, and old wells hide in tall grass, cell service is often nonexistent, and help can be hours away. Tell someone your plans, pack more water than you think you'll need — and save the early morning or late afternoon light for your camera.
