Night sky over Cascade Ridge in the #Adirondacks.

The Adirondack Park has some of the darkest skies in this part of the country. Much of the Adirondack Park is classified as a 2 on the Bortle Scal, a nine-level numeric scale that measures the night sky's brightness. The scale ranges from Class 1, the darkest skies available on Earth, through Class 9, inner-city skies. The Milky Way becomes visible at 3 or 4 on the Bortle scale.
