Upper Fremont Glacier — a glacier in Fremont County, Wyoming at about 3,971 m (13,028 ft) above sea level — is a lesser-known subject for landscape photographers. The nearest town is Pinedale, about 36 km (22 mi) away (Upper Fremont Glacier lies NE of town).
Upper Fremont Glacier is in the Fitzpatrick Wilderness of Shoshone National Forest in the U.S. state of Wyoming. This Wind River Range alpine glacier is associated with the largest grouping of glaciers in the U.S. Rocky Mountains and lies on the north slope of Fremont Peak, the third tallest mountain in Wyoming. Upper Fremont Glacier is at an average altitude of 13,450 ft (4,100 m) and is one of the highest altitude glaciers in the American Rockies.From the Wikipedia article “Upper Fremont Glacier”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
Ice shows its blue best under overcast skies or in shade; bright sun turns glaciers white and flat.

Milky Way & night sky
From Upper Fremont Glacier, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 3.8 hours on a moonless night), and the core peaks around 18° above the southern horizon. Our light-pollution model puts the sky at about Bortle 1 (excellent dark-sky 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: 1 Bortle 1 — Excellent dark-sky site. The Milky Way casts faint shadows; zodiacal light and airglow are obvious. Modeled zenith brightness ≈ 21.94 mag/arcsec². Aurora needs roughly Kp 6.0+ 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 45% average cloud cover) and May as the cloudiest (73%). 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 glacier
- A polarizer deepens the blue of glacial ice and the turquoise of meltwater lakes.
- Include a person or boat for scale — glaciers are much larger than they look.
- Boat tours to tidewater glaciers offer calving shots; use fast shutter speeds and a telephoto.
- Never walk on a glacier without training and gear; crevasses hide under snow bridges.
- Expose carefully: ice and snow fool meters into underexposure, so add +1 to +2 stops.
- Check road and trail conditions with the managing agency before you go.
Season: Summer offers access; late summer exposes the most bare ice before new snow.
Suggested gear: Telephoto lens, Polarizer, Waterproof shell, Spare batteries (cold drains them). Work out exposures with the depth of field, ND filter and NPF rule calculators.
