Milky Way & night sky
From Dead Mountains, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 5.8 hours on a moonless night), and the core peaks around 26° above the southern horizon. Our light-pollution model puts the sky at about Bortle 3 (rural sky), good enough for detailed Milky Way images.

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: 3 Bortle 3 — Rural sky. Some light domes sit on the horizon, but the Milky Way still looks complex overhead. Modeled zenith brightness ≈ 21.57 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show June as the clearest month (about 17% average cloud cover) and December as the cloudiest (43%). July is the warmest month and December the coldest, which matters for gear, snow access and how long batteries last at night.
