National parks like Black Canyon of the Gunnison (@blackcanyonnps) in #Colorado protect some of the last remaining dark #nightskies, which remind us of our connection to the cosmos and serve as a critical resource for animals to navigate, mate and hunt. As the saying goes, half the park is after dark -- stay past sunset to experience #stargazing and solitude away from city lights. #MilkyWay photo courtesy of Tyler Nordgren. #usinterior #findyourpark
