n the early 20th century, America has a dozen national parks, but they are a haphazard patchwork of special places under the supervision of different federal agencies. The conservation movement, after failing to stop the Hetch Hetchy dam, pushes the government to establish one unified agency to oversee all the parks, leading to the establishment of the National Park Service in 1916.
