Teofulio Summit, formerly Warner Pass, a pass that lies at an elevation of 3681 feet in the San Felipe Hills of the Peninsular Ranges of San Diego County, California.
This pass was named for Teofulio Helm (1874-1967), a prominent member of the Cupeno Band of Mission Indians, who homesteaded in the area.
[1] Teofulio Summit is the lowest crossing of the Peninsular Ranges between San Gorgonio Pass, fifty miles north in Riverside County, and San Matias Pass, two hundred miles south in the Baja California Peninsula.
[2] First discovered by Mexican soldiers, Teofulio Summit became the route of the Sonora Road into the coastal region of Southern California.
Later, known as Warner Pass, named after Juan Jose Warner the owner of Warner's Ranch, it was the place where the Southern Emigrant Trail, the major southern route into California for Americans from the east in the middle 19th Century, passed over the mountains from the Colorado Desert to the coastal regions of Southern California.
