Comet — a ghost town in Jefferson County, Montana — is a popular subject for landscape photographers. The nearest town is Boulder, about 9.1 km (5.7 mi) away (Comet lies NNW of town).
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. The town is abandoned except for a single active residence; although it sits on private grazing land, it is open to public access.From the Wikipedia article “Comet, Montana”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Comet, the Milky Way core is visible in a dark sky from April through August. June gives the longest window (about 2.7 hours on a moonless night), and the core peaks around 15° above the southern horizon. Our light-pollution model puts the sky at about Bortle 2 (typical truly dark site), which is excellent for astrophotography.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 2 Bortle 2 — Typical truly dark site. The summer Milky Way shows rich structure; clouds look like black holes in the stars. Modeled zenith brightness ≈ 21.83 mag/arcsec². Aurora needs roughly Kp 4.5+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show July as the clearest month (about 36% average cloud cover) and December as the cloudiest (75%). July is the warmest month and December the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this ghost town
- For interiors with windows, blend two exposures (one for inside, one for the view) instead of relying on HDR alone.
- Old buildings under the Milky Way make strong night images in dark rural skies.
- Look for details: door hinges, faded signs, square nails and window frames tell the story.
- Leave everything as you found it; removing artifacts from public land is illegal.
- Respect private property and closures: many ghost towns are on private land or protected historic sites — never enter unstable buildings.
- Tell someone where you're going in remote areas and carry the ten essentials.
Season: High-elevation mining towns are reachable mostly from June to October; desert ghost towns are best in spring and autumn.
Suggested gear: Wide-angle lens, Tripod, Headlamp, Sturdy boots. Work out exposures with the depth of field, ND filter and NPF rule calculators.
Permits, drones & access
Private property: Many ghost towns sit on private land or protected historic sites. Respect signs, never enter unstable buildings and leave artifacts in place.
