HISTORICAL NOTE

The name of the apostle and patron of the Spains, Santiago (Saint James) was frequently used in Spanish times for place names. Santiago and Modjeska combined, is known locally as "Saddleback". This peak was labeled Santiago Peak when the Geological Survey mapped the Corona Quadrangle in 1894. They also changed the name "Cussing Jim" to "Holy Jim". Santiago Peak is the highest point in Orange County. It is the high point of the Santa Ana mountain range.

SPECIAL CONDITIONS

Silverado Canyon Road and Bedford Road are seasonal, with fire, weather or other closings. Further, Silverado is closed at special times of the year to protect an endangered frog. Check with the Corona Forest Station, Cleveland National Forest at (951) 371-1004.
