Located at the Southern end of the Palisades, Split Mountain (formerly known as South Palisade) is one of California's 14,000 foot peaks and gets its name from its distinctive twin summits (the Northern one is the true summit). The road to the trailhead is reputedly poor and requires a four wheel drive.
Class 2 or 3 from the East.
