Milky Way & night sky
From Upper Big Timber Falls, the Milky Way core is visible in a dark sky from April through August. June gives the longest window (about 2.8 hours on a moonless night), and the core peaks around 15° above the southern horizon. Our light-pollution model puts the sky at about Bortle 1 (excellent dark-sky site), which is excellent for astrophotography.

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 ≈ 21.92 mag/arcsec². Aurora needs roughly Kp 5.0+ 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 39% average cloud cover) and March as the cloudiest (72%). 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.
- Tell someone where you're going in remote areas and carry the ten essentials.
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.
