Conejo Mountain is a 1,814-foot-high mountain (553 m) inVentura County, California, nearCamarillo on the eastern boundary of theOxnard Plain.[1][2][3] At the western edge of theConejo Valley, it is adjacent to theSanta Monica Mountains. Crossing what was once a formidable barrier for travelers,U.S. Route 101 passes through the area on the steepConejo Grade.[4]
The mountain was once a largevolcano about 14 million years ago, but it has been extinct for millions of years. The mountain was under sea level at one point.[5] Mining operations have been ongoing here since 1959, and most of the mountain is owned by the Pacific Rock mining operation.[6]
