While most of us play in our vast system of 63 national parks, others work there. Today, on National Park Service Founders Day, we recognize their efforts and the priceless gift of our country"s national parks. The NPS protects and maintains these parks as well as hundreds of national monuments and other natural, historical, and recreational properties. They include some of our most stunning natural landscapes, like North Cascades National Park in Washington state, featured here.
