We have performed a paleomagnetic study on over 200 oriented samples collected from the Lower Triassic Moenkopi Formation at Bears Ears in southeastern Utah. Seven intervals of normal and reversed magnetic polarities are present at the Bears Ears site. We have correlated these magnetozones to a similar set established in the same formation 130 km to the northeast. At Bears Ears, magnetozone boundaries occur in different lithologic members of the Moenkopi Formation than corresponding magnetozone boundaries present in the section to the northeast. We conclude that contemporaneous lateral variations of sediment type and environment are a characteristic feature of the Moenkopi Formation.
