Located in Pitkin County, Colorado, Hagerman Pass is a mountain pass at about 3,639 m (11,939 ft) above sea level. The nearest town is Leadville North, about 15.7 km (9.8 mi) away (Hagerman Pass lies W of town).
Hagerman Pass, elevation 11,925 ft (3,635 m), is a high mountain pass that crosses the continental divide in the Rocky Mountains of central Colorado in the United States. The pass traverses the Sawatch Range west of Leadville, connecting the headwaters of the Arkansas River on the east with the upper valley of the Fryingpan River above Basalt, in the basin of the Colorado River. The pass was named for James J. Hagerman, builder of the Colorado Midland Railroad. The Colorado Midland railroad crossed the continental divide through one of two tunnels (initially the Hagerman Tunnel (1887), later the Busk-Ivanhoe Tunnel (1893) at lower altitude) near the top of Hagerman pass. The latter tunnel now serves as a water diversion tunnel draining Ivanhoe Lake on the west side of the pass into the Arkansas River basin. In 1909, the Shoshone Transmission Line was built to connect a generating...From the Wikipedia article “Hagerman Pass”, licensed under CC BY-SA 4.0.

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 Hagerman Pass, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 5.0 hours on a moonless night), and the core peaks around 22° 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 ≈ 21.7 mag/arcsec². Aurora needs roughly Kp 8.0+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 44% average cloud cover) and February as the cloudiest (68%). 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
- 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.
- 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.
- Tell someone where you're going in remote areas and carry the ten essentials.
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.
