Trivia: Which location did Theodore Roosevelt declare a national monument?
Mount Rushmore
Grand Canyon
Governors Island
Fort McHenry
The correct answer is Grand Canyon
So why is this answer correct? : In January 1908, President Theodore Roosevelt made 800,000 acres of the Grand Canyon an official national monument, declaring, “Let this great wonder of nature remain as it now is. You cannot improve on it.” Roosevelt used the Antiquities Act to protect important sites from commercial development, with the first such example being Devils Tower in Crook County, Wyoming, in 1906.
