Located in Hoonah-Angoon Census Area, Alaska, Casement Glacier is a glacier at about 645 m (2,116 ft) above sea level. The nearest town is Haines, about 36 km (22 mi) away (Casement Glacier lies SW of town).
Casement Glacier is a 14 miles (23 km) long glacier in the Glacier Bay National Park in Alaska (US). It was named in 1890 by Harry Fielding Reid in honour of R.L. Casement, member of Reid expedition on SS George W. Elder. Back then Casement Glacier was first north tributary of Muir Glacier and not yet completely detached one.From the Wikipedia article “Casement 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/Juneau), 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 February as the clearest month (about 68% average cloud cover) and September as the cloudiest (80%). 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 glacier
- 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.
- A polarizer deepens the blue of glacial ice and the turquoise of meltwater lakes.
- Shoot RAW to keep the most latitude for high-contrast sunrise and sunset scenes.
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.
