Santiago Peak is the southern mountain of the Saddleback landform in Orange County, California. It is the highest and most prominent peak of both the Santa Ana Mountains and Orange County; it also marks a border point with Riverside County. The peak is named for Santiago Creek, which begins on its southwestern slope.[1] During most winters, snow falls at least once on the peak. A telecommunication antenna farm with microwave antennas sits atop the peak.
The Acjachemen referred to the peak as Kalawpa, with the nearby village of Alume meaning "to raise the head in looking upward," in reference to the mountain.[4]
