Grand Canyon is designated a national park
On this day in 1919, President Woodrow Wilson officially designated the Grand Canyon as a national park. The geological wonder would go on to become one of America's most popular tourist attractions.
Formation of the Grand Canyon
Explore the geological history of the Grand Canyon, one of the Seven Natural Wonders of the World.
Located in northwestern Arizona, the Grand Canyon is the product of millions of years of excavation by the mighty Colorado River. The chasm runs exceptionally deep, dropping more than a mile into the earth, and is 15 miles across at its widest point. The canyon is home to more than 1,500 plant species and over 500 animal species, many of them endangered or unique to the area, and its steep, multi-colored walls tell the story of two billion years of Earth’s history.
In 1540, members of an expedition sent by the Spanish explorer Coronado became the first Europeans to discover the canyon—though because of its remoteness, the area was not further explored until 300 years later. American geologist John Wesley Powell, who popularized the term “Grand Canyon” in the 1870s, became the first person to lead a journey across the entire length of the gorge in 1869. The harrowing voyage was made in four rowboats.
In January 1908, U.S. President Theodore Roosevelt designated more than 800,000 acres of the Grand Canyon a national monument. It took more than a decade for it to gain full national park status.
