From Alaska to New York, national monuments can be found in every region of the United States. In total, there are more than 100 existing national monuments for you to explore.

These monuments exist because past presidents and lawmakers had the foresight to protect natural, cultural and historical treasures for future generations.

The Wilderness Society is working with local communities, members of Congress and the presidential administration to see more special places protected as national monuments.
