Long Description:
"The word calavera means skull, which probably comes from the unusual shape of the area's centerpiece, Mount Calavera. The 513-ft. Mount Calavera is not really a mountain at all but rather a 22 million-year-old volcanic plug. A volcanic plug is a mass of volcanic rock that solidified in it's vent and feeding system millions of years ago. When the volcano becomes extinct and starts to erode away, the "plug" is all that is left behind. Mount Calavera is one of only three volcanic plugs in Southern California. In the early 1900's, the ancient plug was mined for gravel. The mining was accomplished by stripping away it's west face and continued into the 1930's. What is left is a rather remarkable blemish on the side of the mountain that somewhat resembles the Grand Canyon. You can easily spot Mount Calavera from either northbound Interstate 5 at Cannon Rd., or westbound on Lake Blvd., just past Oak Riparian Park."
