wilderness policy

When Theodore Roosevelt became President in 1901, he was poised to use his lifelong passion for wildlife and wilderness to direct public policy. While in office, he placed 230 million acres of land under federal protection and established five national parks.

On May 22, 1902, he established Crater Lake National Park in Oregon, depicted in the American marten diorama of the Bernard Family Hall of North American Mammals, adjacent to the Theodore Roosevelt Memorial Hall.

The background of the American marten diorama, which was painted by James Perry Wilson, depicts Crater Lake, the giant water-filled caldera that was created when an immense volcano exploded and collapsed more than 7,000 years ago.
