In 1872, President Ulysses S. Grant signed into law an act creating Yellowstone National Park, dedicating its wondrous geysers and canyons as a public pleasuring-ground for the benefit and enjoyment of the people. This single act sparked a conservation revolution worldwide.
The Birth of the National Park Ideal
Writer and historian Wallace Stegner famously proclaimed: 'National parks are the best idea we ever had. Absolutely American, absolutely democratic, they reflect us at our best rather than our worst.' Today, the National Park Service manages 63 designated National Parks and more than 400 national monuments, battlefields, and historic sites.
Yellowstone: The World's First National Park
Yellowstone sits atop an active volcanic caldera that powers more than 10,000 thermal features, including the famed Old Faithful geyser and the vibrant Grand Prismatic Spring. Covering 2.2 million acres across Wyoming, Montana, and Idaho, it serves as the sanctuary for America's largest continuous bison herd since prehistoric times.
Yosemite's Granite Spires and Waterfalls
