About the Park

The Devil's Punchbowl County Park consists of 1,310 acres and was opened in December 1963. The forty acres where the nature center is located was once in private ownership and was purchased by the County of Los Angeles because of its unique features. Surrounding U.S. Forest Service lands were then added to enhance the park. The Los Angeles County Department of Parks and Recreation now operates this area as one of its Natural Areas facilities. The ranger on duty or volunteer naturalist will be happy to assist you and answer any questions that you may have. The Devil's Punchbowl Nature Center is designed to assist you in learning more about the flora, fauna, and the geological features of the park. The most conspicuous features of the park are geological. The Punchbowl is a deep canyon cut by the runoff of large quantities of water from the higher San Gabriel Mountains occurring over a long period of time. These mountain peaks above the park are 8,000 feet in elevation while the Nature Center is located at 4,740 feet above sea level. The Punchbowl Canyon is 300 feet deep below the vista point. The peculiar uptilted rock formations to be seen in the entire area are layers of sedimentary rocks that were formed long ago by the depositing of loose material in horizontal layers by water. Later they were squeezed into their present steeply-tilted form by the continuing action of uplift along the Punchbowl and Pinyon Faults and pressures along the San Andreas Fault. The Punchbowl Fault is to the south of the rock formation while the Pinyon and San Andreas Faults are to the north.
