The national park system has within it the finest examples of America's heritage.  Its parks are more than superlative scenery and natural phenomena; its monuments preserve historic, prehistoric, and scientific areas of great value. The stories of the nation's growth and ideals are told at historic buildings, important landmarks, battlefield sites, and in inspirational memorials.  In all, they represent America's finest treasures - priceless values that are entrusted to the National Park Services to protect, interpret, and administer for benefit of all citizens.
