Located in Glacier County, Montana, Piegan Glacier is a glacier at about 2,510 m (8,235 ft) above sea level. It lies in or next to Glacier National Park, so park hours, fees and rules apply. The nearest town is North Browning, about 52 km (32 mi) away (Piegan Glacier lies WNW of town).

Piegan Glacier is in Glacier National Park in the U.S. state of Montana. The glacier is situated in a cirque on the southeast slope of Piegan Mountain and just below the summit at an elevation between 8,800 and 8,200 ft (2,700 and 2,500 m) above sea level. The glacier covered an area of approximately 62 acres (0.25 km2) in 2005, a 10 percent reduction in its surface area since 1966. Comparing images of the glacier taken in 1930 with those from 1998, indicates that the glacier experienced relatively little change during that period.From the Wikipedia article “Piegan 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.

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 Piegan Glacier, the Milky Way core is visible in a dark sky from May through July. June gives the longest window (about 2.7 hours on a moonless night), and the core peaks around 12° 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 ≈ 21.93 mag/arcsec². Aurora needs roughly Kp 3.5+ 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 39% average cloud cover) and March as the cloudiest (72%). 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

  • 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.
  • Bring a spare battery — cold weather and long exposures drain them fast.

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.

Permits, drones & access

National Park Service rules. Under federal law (54 U.S.C. 100905), still photography in National Park Service areas needs a permit only when it (1) takes place where members of the public are not allowed, (2) uses models, sets or props that are not part of the location's natural or cultural resources or administrative facilities, or (3) would cause the park to incur additional administrative costs to monitor the activity. Ordinary visitor and most landscape photography needs no permit. Commercial filming rules are separate and have changed in recent years — confirm current requirements with the park before a paid shoot.

Drones: Launching, landing or operating unmanned aircraft (drones) is prohibited in National Park Service units under a 2014 Superintendent's closure (36 CFR 1.5), except where a park has issued specific written approval. Flying from outside the boundary over park land can also violate park rules and disturb wildlife.
