An open letter to Interior Secretary Sally Jewell to bring an end to helicopter overflights at Glacier National Park.

Memorial Day weekend is still weeks away, but winter slowly is releasing its grip on Glacier National Park in Montana, wherethe Many Glacier and Chief Mountain roads have been opened to vehicles for the summer. Visitors are welcome to drive the 8-mile Many Glacier Road as far as the Many Glacier Campground. The Swiftcurrent Nature Trail loop on the valley floor is open in its entirety with parking available at Grinnell Picnic area.

For the next several weeks hikers and cyclists will pretty much have the Going-to-the-Sun Road in Glacier National Park to themselves, as wheeled vehicles are banned while plowing to open the entire 50-mile road continues.

Having already announced earlier this year that the maintenance backlog across the National Park System is closing in on $12 billion, the National Park Service is now highlighting the structural problems with the Arlington Memorial Bridge in Washington, D.C., in a bid to raise congressional awareness of the problems.
