Illustrating America's Natural Heritage

Sites are designated as national natural landmarks in recognition of specific biological communities, geological landforms or processes, or paleontological resources. The outstanding resources at these sites tell the geological and ecological story of America. To draw attention to and spur learning and appreciation of America’s natural heritage, this page provides an introduction to some of the different natural features that can be found across the country. Newly created artwork pieces portray and celebrate the beauty and diversity of each of these natural features.

Limited Permission for Non-Commercial Use of the National Natural Landmarks Program Logo, and Illustrating America's National Heritage Artwork by Site Owners/Managers/Official Partners

The black and white logo (and any NPS-produced color-modified versions) is the official logo (Logo) for the National Natural Landmarks (NNL) Program. Additionally, the NNL Program commissioned Graphic Artist Dennis Caldwell to create unique pieces that artistically represent the diverse biological and geological features represented at NNL sites into a series known as the Illustrating America's Natural Heritage Artwork (Artwork). While the copyright to the original artistic work is now in the public domain, the NNL logo, an NPS trademark, is incorporated into the Artwork.

The National Parks Service (NPS), through the NNL Program, grants permission for NNL site Owners, Managers, and Official Partners to use the Logo and Artwork for educational or promotional uses that align with the program mission as follows:

• Increasing awareness and understanding of NNL sites, designation, and the program,

• Enhancing educational and scientific value and appreciation of natural history, or
• Fostering recognition and support for conservation

For the purposes of these permissions, Official Partners is defined as those with a recognized relationship with the NNL Program or with an NNL site and working directly with site Owners and Managers.

Use of the stand-alone Logo must always be in conjunction with the program name or the official name of the designated NNL site. This permission is non-exclusive and limited to non-commercial uses. Any use of the Logo or Artwork shall not imply a false association with or endorsement by the NPS or associate the NPS or NNL Program with a vice activity. Use of the Logo or Artwork shall immediately cease upon request of the NPS. For high resolution versions of the Logo or Artwork, NNL Owners, Managers, or Official Partners should contact their appropriate regional coordinator.
