National Natural Landmark Program

The National Natural Landmark (NNL) Program, established by the U.S. Department of the Interior, recognizes and promotes the conservation of outstanding natural areas across the country. These landmarks showcase remarkable geological, ecological, or biological features that are important for scientific research, education, and public appreciation. While designated landmarks are preserved through partnerships and recognition rather than strict legal protection, the program aims to raise awareness about natural heritage and encourage conservation efforts for these unique and significant landscapes.
