Atigun Pass — a mountain pass in North Slope Borough, Alaska at about 1,467 m (4,813 ft) above sea level — is a popular subject for landscape photographers.
Atigun Pass ( AT-i-gən), elevation 4,739 feet (1,444 m), is a high mountain pass across the Brooks Range in Alaska, located at the head of the Dietrich River. It is where the Dalton Highway crosses the Continental Divide (at mile marker 244), and is the highest pass in Alaska that is maintained throughout the year. Atigun is the only pass in the Brooks Range that is crossed by a road. The pass has been responsible for taking many drivers off the road and is also home to avalanches during the winter. Atigun is known among bush pilots for the difficulty of crossing the pass with small planes; Anaktuvuk Pass is favored as the safer flying route. The pass is often shown on the third and fourth seasons of the History Channel reality series Ice Road Truckers, which focuses on the challenges of driving on the Dalton Highway.From the Wikipedia article “Atigun Pass”, licensed under CC BY-SA 4.0.
Sunrise & sunset directions
At this latitude the sun does not rise or set on some days of the year, so check the monthly table below for daylight and twilight.

Azimuth is measured clockwise from true north (90° = east, 270° = west). Computed for 2026; values change by less than a degree from year to year.
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/Anchorage), 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
The Milky Way's bright core (in Sagittarius) barely clears the southern horizon at this latitude, so focus on winter Milky Way, aurora or star trails instead.

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: 1 Bortle 1 — Excellent dark-sky site. The Milky Way casts faint shadows; zodiacal light and airglow are obvious. Modeled zenith brightness ≈ 21.95 mag/arcsec². Aurora needs roughly Kp 0.0+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show March as the clearest month (about 46% average cloud cover) and August as the cloudiest (78%). 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.
