Sequoia & Kings Canyon
Moro Rock is a dome-shaped granite monolith. Common in the Sierra Nevada, these domes form by exfoliation, the spalling or casting off in scales, plates, or sheets of rock layers on otherwise unjointed granite. Outward expansion of the granite results in exfoliations. Expansion results from load relief; when the overburden that once capped the granite has eroded away, the source of compression is removed and the granite slowly expands. Fractures that form during exfoliation tend to cut corners. This ultimately results in rounded dome-like forms.
The General park map handed out at the visitor center is available on the park's map webpage.For information about topographic maps, geologic maps, and geologic data sets, please see the geologic maps page.
A geology photo album for this park can be found here.For information on other photo collections featuring National Park geology, please see the Image Sources page.
Currently, we do not have a listing for a park-specific geoscience book. The park's geology may be described in regional or state geology texts.
Parks and Plates: The Geology of Our National Parks, Monuments & Seashores.
Lillie, Robert J., 2005.
W.W. Norton and Company.
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.
Current research projects in Sequoia and Kings Canyon National Parks (SEKI) are being conducted by the National Park Service, USDA Forest Service, the Biological Resources Division (BRD) of the USGS, or by several universities. These include several projects being conducted in the East Fork watershed in association with the Mineral King Risk Reduction Project (MKRRP).
Information about the park's research program is available on the park's research webpage.
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.
