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 46% average cloud cover) and August as the cloudiest (78%). 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 scenic viewpoint
- A panorama of 3–5 vertical frames gives more resolution and a wider view without a fisheye look.
- Blue hour after sunset is excellent for towns or roads below the viewpoint as lights come on.
- Arrive 30–45 minutes before sunrise or sunset to find a composition before the light peaks.
- Use a telephoto (70–200 mm) to isolate layered ridges and light rays instead of shooting only wide.
- Check road and trail conditions with the managing agency before you go.
Season: Clear, dry air in autumn and after winter storms gives the longest views; summer adds wildflowers but also haze.
Suggested gear: Tripod, Telephoto lens, Graduated ND filter, Headlamp. Work out exposures with the depth of field, ND filter and NPF rule calculators.
