About: The National Park Emblem

The National Park Service (NPS) emblem, commonly known as the Arrowhead, is one of the most recognizable symbols of the United States federal government. Adopted in 1951, this iconic logo serves as a visual mission statement, representing the agency’s commitment to preserving America’s natural and cultural treasures.

Symbolism of the NPS Arrowhead

Each element within the emblem was carefully chosen to represent a specific facet of the National Park System:

• The Arrowhead Shape: Represents history and archaeology, honoring the cultural heritage and the deep human history preserved within national monuments and historic sites.

• The Sequoia Tree: Symbolizes vegetation and floral resources, standing for all plant life protected across the country’s diverse ecosystems.

• The Bison: Represents wildlife, signifying the conservation of animals—from the massive herds of the Great Plains to the smallest protected species.

• The Mountains: Stand for scenic and geological values, highlighting the majestic landscapes, rock formations, and recreational opportunities like hiking and climbing.

• The Water: Represented by the lake and ripples, this element symbolizes aquatic resources and the importance of water-based recreation, such as fishing and boating.

History and Evolution

• The emblem was authorized on July 20, 1951, by Secretary of the Interior Oscar L. Chapman. It was designed by a team of NPS employees, including Herbert Maier and Aubrey Neasham, who sought a “rustic” look that better captured the spirit of the outdoors than previous, more formal designs.

Today, the Arrowhead is a protected trademark. You can find it on the “flat hats” of park rangers, visitor center signage, and official brochures. It remains a powerful reminder of the NPS mission: to preserve these lands “unimpaired for the enjoyment of future generations.”
