Paleomagnetic results from the Eocene igneous rocks of the Rattlesnake Hills in central Wyoming have added 9 reliable virtual geomagnetic pole positions to previous paleomagnetic data from the area. These new data when combined with corrected results from the previous study yield a paleomagnetic pole located at 146.2° E, 79.4° N; α 95 = 9.6°. This pole position, at about 44 mybp, agrees very well with other Eocene paleopole determinations for stable North America. The proximity of these pole positions to the present rotation axis shows that most of the angular distance between the apparent pole position for the Late Cretaceous and the present was closed in the Paleocene and/or early Eocene.
