National Park Service

Managing the country's more than 400 national parks, trails, sites, memorials, and more, takes the help of more than 20,000 men and women employed by the National Park Service, which is celebrating it's centennial birthday in August. For some, preserving all that history and heritage is more than just a job, it's a passion!

Building bridges, swinging an axe and living in a yurt are all part of normal life for a trail worker at Glacier National Park.
