两个玄武岩流爆发了大约108万年。1980年以前在加州科索山脉的10个地磁场具有正常磁极性，从而为科布山正极性事件提供了新的证据。对现有数据的审查证实，这一事件是地磁起源。平均年龄为1.10 ± 0.02百万岁。发现科布山正极性事件的B.P.最适合所有可用的辐射测量和地质数据。
Two basalt flows which erupted about 1.08 m.y. ago in the Coso Range, California, have normal magnetic polarity and thus provide additional evidence for the Cobb Mountain normal polarity event. A review of available data confirms that this event was of geomagnetic origin. A mean age of 1.10 ± 0.02 m.y. B.P. for the Cobb Mountain normal polarity event was found to best fit all available radiometric and geologic data.
