Milky Way & night sky
From Gentry Creek Falls, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 5.5 hours on a moonless night), and the core peaks around 25° above the southern horizon. Our light-pollution model puts the sky at about Bortle 3 (rural sky), good enough for detailed Milky Way images.

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 ≈ 21.66 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show October as the clearest month (about 52% average cloud cover) and February as the cloudiest (66%). 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.
- Scout in daylight if you plan to shoot at night or before sunrise.
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.
