National Natural Landmarks

National Natural Landmarks (NNLs) are exceptional natural areas in the United States that showcase significant geological features, natural ecosystems, or unique habitats. Designated by the National Park Service, these sites highlight the country's natural heritage and aim to promote conservation and education. NNLs can include mountains, canyons, wetlands, and unique flora or fauna. While they are not national parks or protected areas, their designation helps raise awareness and support for their preservation, allowing visitors to appreciate the country's natural beauty and ecological diversity.
