Split Rock is a familiar feature to those who boulder at Stoney Point, a climbing area northwest of Los Angeles. It's usually one of the first "chimney climbs" done by the novice climber.

The dedicated traditional climber can learn much about chimneying and off-width cracks by climbing the differing widths of the split. There is also an excellent 5.10c or 5.10d top rope route in an adjoining corner that involves a delicate combination of fingertip jamming, stemming and liebacking.

This photograph was taken about 1971, as evidenced by the Robbin's "blue boots" the climber is wearing.
