North Klawatti Glacier is a glacier in Skagit County, Washington at about 1,711 m (5,614 ft) above sea level. It lies in or next to North Cascades National Park, so park hours, fees and rules apply. The nearest town is Darrington, about 52 km (32 mi) away (North Klawatti Glacier lies NE of town).
North Klawatti Glacier lies in a cirque to the east of Austera Peak, North Cascades National Park, in the U.S. state of Washington. The glacier is approximately 1.4 mi (2.3 km) in length, .40 mi (0.64 km) in width at its widest and descends from 7,800 to 6,000 ft (2,400 to 1,800 m), where it terminates above Klawatti Lake. An arête divides North Klawatti Glacier from Klawatti Glacier to the south. In 1993, it had an area of 1.48 km2. The North Klawatti Glacier was one of four glaciers selected for glacier mass balance research. From 1993 (when monitoring began) to 2013 the glacier had lost ~8 m of thickness.From the Wikipedia article “North Klawatti 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 North Klawatti Glacier, the Milky Way core is visible in a dark sky from May through July. May gives the longest window (about 1.0 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 2 (typical truly dark 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: 2 Bortle 2 — Typical truly dark site. The summer Milky Way shows rich structure; clouds look like black holes in the stars. Modeled zenith brightness ≈ 21.74 mag/arcsec². Aurora needs roughly Kp 4.0+ 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 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
- 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.
- 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.
- Tell someone where you're going in remote areas and carry the ten essentials.
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.
