Humes Glacier is a glacier in Jefferson County, Washington at about 1,657 m (5,436 ft) above sea level. It lies in or next to Olympic National Park, so park hours, fees and rules apply. The nearest town is Port Angeles, about 40 km (25 mi) away (Humes Glacier lies SSW of town).
Humes Glacier is located in the Olympic Mountains in Olympic National Park, approximately 2.25 miles (3.62 km) southeast of the summit of Mount Olympus. The glacier starts at nearly 6,000 ft (1,800 m) and descends downslope 1.25 mi (2.01 km), terminating at 4,800 ft (1,500 m) above sea level. It was named by members of The Mountaineers climbing club in 1907 for Grant and Will Humes, who were guides, explorers, and pack-train operators.From the Wikipedia article “Humes 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/Los Angeles), 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 Humes Glacier, the Milky Way core is visible in a dark sky from April through August. June gives the longest window (about 1.7 hours on a moonless night), and the core peaks around 13° above the southern horizon. Our light-pollution model puts the sky at about Bortle 3 (rural sky), good enough for detailed Milky Way images.

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: 3 Bortle 3 — Rural sky. Some light domes sit on the horizon, but the Milky Way still looks complex overhead. Modeled zenith brightness ≈ 21.59 mag/arcsec². Aurora needs roughly Kp 4.5+ 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 46% average cloud cover) and January as the cloudiest (80%). August 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.
- 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.
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.
