A National Natural Landmark is a designation given by the United States government to recognize and protect areas that showcase outstanding natural features. These landmarks can include unique geological formations, significant ecosystems, or exceptional examples of natural history. The program aims to preserve these sites for their educational, scientific, and recreational value. Established in 1962, the National Natural Landmarks program is managed by the National Park Service. While the designation does not provide federal ownership, it encourages conservation efforts and promotes public awareness of the importance of preserving natural heritage. Examples of such landmarks include the Grand Canyon and the Florida Everglades.
