The National Parks: America's Best Idea

While visiting the parks was once predominantly the domain of Americans wealthy enough to afford the high-priced train tours, the advent of the automobile allows more people than ever before to visit the parks. Mather embraces this opportunity and works to build more roads in the parks. Some park enthusiasts, such as Margaret and Edward Gehrke of Nebraska, begin "collecting" parks, making a point to visit as many as they can. In North Carolina, Horace Kephart, a reclusive writer, and George Masa, a Japanese immigrant, launch a campaign to protect the last strands of virgin forest in the Smoky Mountains by establishing it as a park. In Wyoming, John D. Rockefeller Jr. begins quietly buying up land in the Teton Mountain Range and valley in a secret plan to donate it to the government as a park.

To battle unemployment in the Great Depression, Franklin D. Roosevelt creates the Civilian Conservation Corps, which spawns a "golden age" for the parks through major renovation projects. In a groundbreaking study, a young NPS biologist named George Melendez Wright discovers widespread abuses of animal habitats and pushes the service to reform its wildlife policies. Congress narrowly passes a bill to protect the Everglades in Florida as a national park—the first time a park has been created solely to preserve an ecosystem instead of scenic beauty. As America becomes entrenched in World War II, Roosevelt is pressured to open the parks to mining, grazing, and lumbering. The president also is subjected to a storm of criticism for expanding the Grand Teton National Park in Wyoming by accepting a gift of land secretly purchased by John D. Rockefeller Jr.

Following World War II, the parks are overwhelmed as visitation reaches 62 million people a year. A new billion-dollar campaign—Mission 66—is created to build facilities and infrastructure that can accommodate the flood of visitors. A biologist named Adolph Murie introduces the revolutionary notion that predatory animals, which are still hunted, deserve the same protection as other wildlife. In Florida, Lancelot Jones, the grandson of a slave, refuses to sell to developers his family's property on a string of unspoiled islands in Biscayne Bay and instead sells it to the federal government to be protected as a national monument. In the late 1970s, President Jimmy Carter creates an uproar in Alaska when he sets aside 56 million acres of land for preservation—the largest expansion of protected land in history. In 1995, wolves are re-established in Yellowstone, making the world's first national park a little more like what it once was.
