The paleomagnetic pole positions of Mars obtained by modeling 10 small‐size, isolated magnetic anomalies show considerable clustering, 7 out of 10 are within a circle of 30 degrees radius centered at (230E, 25N). The directions of the magnetization of some nearby source bodies differ by ∼180 degrees and both north and south poles are found in the cluster, suggesting the magnetic pole reversals of Mars.
