White Chuck Glacier is a glacier in Snohomish County, Washington at about 2,123 m (6,965 ft) above sea level. It is part of Glacier Peak Wilderness. It sits roughly 42 km (26 mi) ESE of Darrington.
White Chuck Glacier is located in the Glacier Peak Wilderness in the U.S. state of Washington and is 3.5 mi (5.6 km) south of Glacier Peak. The glacier is within Mount Baker-Snoqualmie National Forest and nearly touches the White River Glacier though they are separated by an arête off the Kololo Peaks. White Chuck Glacier has retreated significantly since the end of the Little Ice Age. From about 1850 to 1930, the glacier thinned and by 1940, a fast rate of retreat commenced. By 1955, the glacier had three separate termini and by 2005, the northern terminus was gone. Several small proglacial lakes have been left behind by the retreating glacier. Between 1958 and 2005 White Chuck Glacier lost more than half its surface area.From the Wikipedia article “White Chuck 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 White Chuck Glacier, the Milky Way core is visible in a dark sky from April through July. June gives the longest window (about 1.3 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 ≈ 21.57 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 42% average cloud cover) and November as the cloudiest (76%). 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
- 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.
Permits, drones & access
Drones: Drones may not take off from or land in federally designated wilderness, where mechanized equipment is prohibited under the Wilderness Act.
