Star Trails over Alamo Lake

From the photographer: “Two and a half hours of circumpolar star trails are photographed under a moonlit sky at Alamo Lake State Park. Alamo Lake is one of the best dark sky sites in all of Arizona and remains relatively free of light pollution. The distinctive peak in the background is Artillery Peak.”
