What the night sky looks like over Jackson, WY

Jackson reads as suburban edge on this dataset's scale. A noticeable glow near the horizon. Brighter stars and constellations are easy to pick out; the Milky Way is washed out. Only 21.1% of the 3,206 cities measured here read darker than Jackson.

The number comes from orbit, not a stargazer's logbook, so treat it as an estimate of sky glow rather than a certified Bortle class.
