The Ammonite Point Visitor Information Center is located within the Grand Canyon National Park and acts as a focal point for visitors interested in the geological wonders of the area. Drawing inspiration from the Ammonite fossil known for its spiral shape, the design aims to connect with the natural landscape. The pavilion serves as a platform for educational opportunities, displaying fossils and insights into the geological history that has developed over millions of years.

Design Concept

The entryway is purposefully narrow, designed to create the feeling of moving through a natural crevice or cave. This initial constriction draws visitors inside, transitioning them into a more open exhibition area where they can learn about the fossils that tell the story of the earth's history. This journey through varying spaces not only enhances curiosity but also invites exploration and interaction with the displays.

Spatial Organization

Inside the center, seating areas are integrated into the walls, providing practical spaces for visitors to relax. These areas also support educational sessions, allowing park rangers to share knowledge in a comfortable setting. The layout encourages engagement, ensuring that both the design and the exhibits work together to enrich the visitor experience and promote an understanding of the geological significance of the Grand Canyon.

Connection to Landscape

As visitors make their way through the pavilion, they encounter another narrowing that leads to a generous opening revealing impressive views of the Grand Canyon. This design element emphasizes the relationship between the built environment and the natural setting, guiding guests to a thoughtfully positioned viewpoint. The architecture enhances the experience by allowing visitors to fully appreciate the beauty surrounding them.

Materiality and Integration

Rammed earth is used for the walls, a material that reflects the geological context of the Grand Canyon. This choice connects the structure to the land, evoking the layers of earth that make up the canyon. A single Juniper tree is placed within the central area, providing shade and a natural focal point for visitors. This integration of natural elements enhances the sensory experience while grounding the pavilion in its environment.
