Located in Yukon-Koyukuk Census Area, Alaska, Walker Lake is a lake. It is part of Gates of the Arctic National Park and Preserve.
Walker Lake (Iñupiaq: Qalugluktuaq; Denaakk'e: Taah K'ehoolaanh) is the source of the Kobuk River in northwestern Alaska (emptying into Kotzebue Sound). The lake is located near the easternmost part of Northwest Arctic Borough, deep in the remote interior of Alaska, on the South slope of the Brooks Range, and is approximately 1 mile by 14 miles. Explored during an expedition led by John C. Cantwell in 1885, under the authority of the Revenue Marine. Also known as "Big Fish Lake", Inupiaq legend in the area told of giant, ferocious fish that inhabited the waters. An attempt by a native with the Cantwell expedition to catch one of these giant fish involved a hook made of an entire set of reindeer antlers baited with a whole goose. In 1968, Walker Lake, was designated as a National Natural Landmark by the National Park Service. It was later incorporated into Gates of the Arctic National Park.From the Wikipedia article “Walker Lake (Northwest Arctic, Alaska)”, licensed under CC BY-SA 4.0.

Local time (America/Anchorage), 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 March as the clearest month (about 42% average cloud cover) and July 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 lake
- Include shoreline rocks, reeds or a log as foreground to give the reflection depth.
- Expose for the brighter sky; reflections are typically half a stop to a stop darker.
- After sunset, long exposures smooth wind ripples into glass.
- For mirror reflections, get low and close to the water; the reflection grows with a lower camera.
- A polarizer can remove reflections to show the lakebed — or keep them, depending on rotation.
- Check road and trail conditions with the managing agency before you go.
Season: Autumn mornings bring mist and fall color; high-elevation lakes are usually ice-free only from early summer to mid-autumn.
Suggested gear: Tripod, Circular polarizer, Wide-angle lens, Waterproof boots. Work out exposures with the depth of field, ND filter and NPF rule calculators.
