Located in Silver Bow County, Montana, Deer Lodge Pass is a mountain pass at about 1,805 m (5,922 ft) above sea level. The nearest town is Butte, about 17.2 km (10.7 mi) away (Deer Lodge Pass lies SW of town).
Deer Lodge Pass, elevation 5,879 ft (1,792 m), is a mountain pass on the Continental Divide in southwestern Montana, about 11 miles southwest of Butte. It is traversed by Interstate 15 and is one of three crossings of the Divide by I-15 (all in Montana), the others being Monida Pass (on the border with Idaho) and Elk Park Pass north of Butte. Unlike most other passes in western Montana, Deer Lodge Pass is in the midst of treeless, rolling hills (reminiscent of Interstate 80 in Wyoming), and the grades on the highway are relatively gentle. About 0.7 miles (1.1 km) west of the highway crossing is a slightly lower pass, elevation 5,801 ft (1,768 m), that carries a branch line of the Union Pacific Railroad across the Divide. This is sometimes also referred to as Deer Lodge Pass, but the official railroad name for this location is Feely.

Golden hour & blue hour by month
Mountain passes sit above valleys, so they reward sunrise and sunset with layered ridges, valley fog and long shadows.

Milky Way & night sky
From Deer Lodge Pass, the Milky Way core is visible in a dark sky from April through August. June gives the longest window (about 2.8 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 3 (rural sky), good enough for detailed Milky Way images.

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: 3 Bortle 3 — Rural sky. Some light domes sit on the horizon, but the Milky Way still looks complex overhead. Modeled zenith brightness ≈ 21.66 mag/arcsec². Aurora needs roughly Kp 5.0+ 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 March as the cloudiest (71%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this mountain pass
- Summit pull-outs often face one direction; use the sun azimuth table to see whether sunrise or sunset suits the view.
- Wildflowers bloom late at pass elevations — often July to early August in the Rockies and Sierra.
- Check road status before driving: many high passes close seasonally or after storms.
- Look for the road itself as a leading line — switchbacks from above make strong compositions.
- Weather changes fast at elevation; carry layers even in summer.
- Bring a spare battery — cold weather and long exposures drain them fast.
Season: Summer and early autumn are the main season; winter visits depend on plowing and avalanche conditions.
Suggested gear: Telephoto lens, Tripod, Warm layers, Road-condition app. Work out exposures with the depth of field, ND filter and NPF rule calculators.
