Golden hour & blue hour by month
Steam is most visible on cold mornings; backlight from a low sun makes rising steam glow.

Milky Way & night sky
From Kellog Hot Springs, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.5 hours on a moonless night), and the core peaks around 20° above the southern horizon. Our light-pollution model puts the sky at about Bortle 1 (excellent dark-sky 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: 1 Bortle 1 — Excellent dark-sky site. The Milky Way casts faint shadows; zodiacal light and airglow are obvious. Modeled zenith brightness ≈ 21.91 mag/arcsec². Aurora needs roughly Kp 8.0+ 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 18% average cloud cover) and December 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 hot spring
- Respect bathers' privacy: ask before including people at soaking pools.
- Wind direction determines where steam drifts; shoot from the upwind side to see the pool.
- Condensation forms quickly on lenses; let gear acclimate and carry a cloth.
- Keep to boardwalks and marked paths — crusts around thermal features can be thin and the water dangerously hot.
- Check road and trail conditions with the managing agency before you go.
Season: Winter gives the most dramatic steam; some primitive springs are only accessible in summer.
Suggested gear: Circular polarizer, Lens cloth, Telephoto for distant pools. Work out exposures with the depth of field, ND filter and NPF rule calculators.
