Located in Anchorage Municipality, Alaska, Thunderbird Falls is a waterfall. The nearest town is Knik-Fairview, about 15.0 km (9.3 mi) away (Thunderbird Falls lies ESE of town).
Thunderbird falls is a waterfall located in Eklutna, Alaska. It has an elevation of about 100 feet and flows into the Eklutna River. Due to its proximity to Anchorage, about a thirty-minute drive, it is a popular place for tourists and those living nearby. The waterfall is comingled with a 1.6-mile round trip hike to attract people, especially those with young children and tourists, to the falls and the Chugach State Park, where it resides. The path has two main routes with the final destination being the only difference. The easier first route ends at a viewing deck near the top of the falls, whereas the second one is harder to traverse, but will end closer to the bottom of the falls.From the Wikipedia article “Thunderbird Falls”, licensed under CC BY-SA 4.0.

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: 4 Bortle 4 — Rural / suburban transition. Light domes are visible in several directions; the Milky Way is clear but lacks detail near the horizon. Modeled zenith brightness ≈ 21.19 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 63% average cloud cover) and July as the cloudiest (83%). 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 waterfall
- Keep a microfiber cloth handy — spray drifts onto the lens, especially at the plunge pool.
- Bracket shutter speeds: 1/8 s, 1/2 s and 2 s give very different water textures and you can choose later.
- A 3-stop ND filter lets you use slow shutter speeds even when the light is bright.
- Shoot a vertical and a horizontal frame; tall falls often work better in portrait orientation.
- Bring a spare battery — cold weather and long exposures drain them fast.
Season: Peak flow is usually in late spring; autumn adds color around the falls, and winter can bring ice formations at colder locations.
Suggested gear: Tripod, Circular polarizer, 3–6 stop ND filter, Lens cloth, Waterproof footwear. Work out exposures with the depth of field, ND filter and NPF rule calculators.
