Grand Canyon National Park

The Grand Canyon National Park is a 1,217,262 acre park in northwestern Arizona that was established on February 26, 1919. The park's central feature is the Grand Canyon, a gorge of the Colorado River, which was designated a World Heritage Site by UNESCO in 1979. The park receives over 4.7 million visitors annually and celebrated its 100th anniversary on February 26, 2019. The park's creation was an early success of the conservation movement, which may have helped thwart proposals to dam the Colorado River within its boundaries.learn more on wikipedia
