Ohio Pass — a mountain pass in Gunnison County, Colorado at about 3,068 m (10,066 ft) above sea level — is a lesser-known subject for landscape photographers. The nearest town is Crested Butte, about 9.8 km (6.1 mi) away (Ohio Pass lies WSW of town).
Ohio Pass (elevation 10,065 feet (3,068 m)) is a mountain pass in Gunnison County, Colorado, located one mile southeast of Kebler Pass. Gunnison County Road 730 (Forest Road 730) traverses the pass, which is a gap between Mount Axtell and Ohio Peak in the Anthracite Range, part of the West Elk Mountains. The pass divides the waters of Ruby Anthracite Creek to the north and Ohio Creek to the south.From the Wikipedia article “Ohio 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.

Local time (America/Denver), including daylight saving time. Golden hour runs from about −4° to +6° solar altitude, so the morning golden hour begins during blue hour, before sunrise.
Milky Way & night sky
From Ohio Pass, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 5.2 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 ≈ 21.84 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 June as the clearest month (about 39% average cloud cover) and February as the cloudiest (66%). 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
- 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.
- 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.
- Scout in daylight if you plan to shoot at night or before sunrise.
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.
