Milky Way & night sky
From Cowan Lake State Park, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 5.0 hours on a moonless night), and the core peaks around 22° above the southern horizon. Our light-pollution model puts the sky at about Bortle 4 (rural / suburban transition), 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: 4 Bortle 4 — Rural / suburban transition. Light domes are visible in several directions; the Milky Way is clear but lacks detail near the horizon. Modeled zenith brightness ≈ 20.75 mag/arcsec². Aurora needs roughly Kp 7.0+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 45% average cloud cover) and January as the cloudiest (77%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.
