Question: In southwestern Colorado, a national park created in 1906 was the first in the country established to protect human handiwork rather than natural scenery. What park is it?

Answer: Mesa Verde National Park. President Theodore Roosevelt established it in 1906 to “preserve the works of man,” the first national park of its kind. It protects nearly 5,000 archaeological sites, including about 600 cliff dwellings built by the Ancestral Pueblo people.
