Impressive exhibits chronicle the history of the mountain and capture its majesty. A rock wall with instructional video examines the geological forces which created the mountain. Panels describe the native American history of the region. A diorama, complete with native sounds, offers an overview of the park's ecosystems. A model of the mountain acquaints visitors with important park locations. Splendid photographs enhance the visitor's experience.

In addition to the exhibits, the summit museum features a gift shop and audio-visual room.

On the walk up the circular stairway to the observation deck, visitors are treated to a look at ancient marine fossils embedded in the sandstone walls of the summit building.

Above the rotunda is a beacon, historically important to aviators and now lighted once a year on December 7 in memory of those who lost their lives at Pearl Harbor.

Mitchell Canyon Visitor Center

The Mitchell Canyon Interpretive Center is located in Mount Diablo State Park at the south end of Mitchell Canyon Road in Clayton,CA. The Mitchell Canyon Visitor Center is staffed by State Park Volunteers and is supported by the Mount Diablo Interpretive Association whose main goal is to provide visitors with information so they can better enjoy the Park and it's natural wonders. The Center is currently open on Saturdays and Sundays, and some holidays 8am to 4pm during spring and summer months and 9am to 3pm during fall and winter months.

The Center has displays about various aspects of Mt. Diablo State Park, such as geology, wildlife, trails, and plant life. Interpretive materials about the Park, such as geology, wildlife, and plants, are for sale. There are also postcards, note cards, trail maps, and water for sale. A docent is on duty when the Center is open to answer questions and to handle sales of materials. In the future the Center will also serve as a focal point in Mitchell Canyon for scheduled group hikes and lectures. We welcome all visitors to this part of the State Park to stop in and see the new Mitchell Canyon Visitor Center.

If you would like to volunteer for this program, please contact Sue Donecker, Visitor Center Coordinator (925) 673-3356 or email inquiry. Also see recent article from "Mountain News".
