Milky Way & night sky
From Gates of the Mountains Wilderness, the Milky Way core is visible in a dark sky from April through August. June gives the longest window (about 2.2 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.
