Last month, former Glacier National Park Superintendent Jeff Mow joined more than 40 former national park superintendents in signing a letter urging the federal government to close National Park Service sites in the event of a government shutdown. A bright red banner across the websites for Glacier and Yellowstone national parks states that national parks “remain as accessible as possible” during the shutdown, but services may be limited or unavailable. For example, Glacier National Park’s Going-to-the-Sun Road typically closes the third Monday of October, but that is contingent on weather conditions along the alpine stretches of the 50-mile scenic byway. According to Glacier’s official social media accounts, the National Park Service “will continue to share critical information about park access, safety, and resources. Emails sent to the National Park Service’s media office about what constitutes “critical information about park access” went unanswered.
