Bighorn River Zodiacal Light
I don't think I've ever seen the zodiacal light glow this prominently before. As soon as it became dark enough it jumped out at me right away. The ghostly glow is caused by the sun illuminating dust within our solar system. The glow extends diagonally along the path of the ecliptic, also known as the zodiac. Only under very dark skies like this spot near St Xavier, Montana, are views like this possible.
