Milky Way & night sky
From Rocking Chair Butte, the Milky Way core is visible in a dark sky from April through August. June gives the longest window (about 2.3 hours on a moonless night), and the core peaks around 14° 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 ≈ 21.94 mag/arcsec². Aurora needs roughly Kp 4.0+ 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 40% average cloud cover) and February as the cloudiest (68%). 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 rock formation
- Stay on trails; desert soils and lichens take decades to recover from footprints.
- Find a spot where the formation sits against open sky to emphasize its silhouette.
- At night, a formation under the Milky Way or star trails makes a strong anchor.
- Use the sunrise and sunset azimuths below to know which face will be lit.
- Bring a spare battery — cold weather and long exposures drain them fast.
Season: Spring and autumn are best in desert regions; winter snow on red rock is rare but spectacular.
Suggested gear: Wide and telephoto lenses, Tripod, Headlamp. Work out exposures with the depth of field, ND filter and NPF rule calculators.
