Milky Way & night sky
From Double Arrow Lookout, the Milky Way core is visible in a dark sky from April through August. June gives the longest window (about 2.0 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 2 (typical truly dark 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: 2 Bortle 2 — Typical truly dark site. The summer Milky Way shows rich structure; clouds look like black holes in the stars. Modeled zenith brightness ≈ 21.89 mag/arcsec². Aurora needs roughly Kp 4.5+ 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 36% average cloud cover) and March as the cloudiest (73%). July is the warmest month and December the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this fire lookout
- Some lookouts can be rented overnight through recreation.gov, which puts you on site for both sunset and sunrise.
- Shoot the tower itself against the Milky Way or star trails on clear, moonless nights.
- Haze from wildfire smoke can turn the sun deep red but reduce visibility; check air quality.
- Access roads may be rough or seasonal.
- Bring a spare battery — cold weather and long exposures drain them fast.
Season: Summer and early autumn; many towers are staffed only during fire season.
Suggested gear: Wide and telephoto lenses, Tripod, Warm layers. Work out exposures with the depth of field, ND filter and NPF rule calculators.
