On August 25, 1916, President Woodrow Wilson signed the act creating the National Park Service. The “Organic Act” states that the fundamental purpose of the NPS “is to conserve the scenery and the natural and historic objects and the wild life therein and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations.”

The National Park Service turned 100 last year, and they've been busy. They continuously work to protect 407 sites with 28 different designations. These include 127 historical parks or sites, 78 national monuments, 59 national parks, 25 battlefields or military parks, 19 preserves, 18 recreation areas, 10 seashores, four parkways, four lakeshores, and two reserves.

On a trivia quiz about national parks a question about Isle Royale being closed in the winter you mentioned the wind from Lake Michigan but Isle Royale is in Lake Superior.
Don't mean to be picky, but regarding No. 28, Mammoth Cave is only mapped at 400 miles. Still -- miles worth seeing!
