Coronado National Memorial, Arizona

Coronado National Memorial is located in the southeast corner of Arizona, right near the Mexico border. This memorial was established to commemorate the first major exploration of the southwestern part of the United States by Europeans. Featured in the memorial is a view of the valley through which the exploration of Coronado first entered the current boundaries of the US. From this view, one can see the San Rafael Valley, the Patagonia Mountains and the Santa Rita Mountains. On clear days it is even possible to see the summit of Baboquivari Peak (7,720 feet) which is 80 miles away from Coronado National Memorial. The goal of the expedition through this area was to find the fabled golden Cities of Cibola.

Geographically, the memorial is situated on the border of Mexico and Arizona. The Huachuca Mountains make up the northern boundary of the memorial. Most of the area of Coronado National Memorial is known as the Montezuma caldera. This caldera is made up of some pretty complex geology. It was formed as a result of cataclysmic eruptions with more volcanic events following. In some areas of the park there is relatively young Cretaceous rock which is covered by much older Jurassic and Pennsylvanian-Permian layers. This complex geology is complicated further by the intrusion of Tertiary rocks into the formations.

9" x 10.75", paperback, 550 pages, full color throughout

The spectacular geology in our national parks provides the answers to many questions about the Earth. The answers can be appreciated through plate tectonics, an exciting way to understand the ongoing natural processes that sculpt our landscape. Parks and Plates is a visual and scientific voyage of discovery!

Ordering from your National Park Cooperative Associations' bookstores helps to support programs in the parks. Please visit the bookstore locator for park books and much more.

geologic research subheading

For information about permits that are required for conducting geologic research activities in National Parks, see the Permits Information page.

The NPS maintains a searchable data base of research needs that have been identified by parks.

A bibliography of geologic references is being prepared for each park through the Geologic Resources Evaluation Program (GRE). Please see the GRE website for more information and contacts.
