Happy100th! National Park Service Turns 100

National Park Service turns 100The National Park Service is celebrating its centennial Thursday, having spent its first 100 years dedicated to preserving “unimpaired the natural and cultural resources and values” of America’s national parks. The first National Park was actually designated in 1871, with President Ulysses S. Grant signing the legislation in 1872 to preserve Yellowstone National Park, but the current iteration of the NPS was established by President Woodrow Wilson “to conserve the scenery and the natural and historic objects and … wildlife therein.” Last year, more than 300 million people visited National Parks, and in honor of its 100th anniversary the NPS is offering free admission to all 412 parks from Aug. 25-28.
