**Figure 5.** **A.** Average inclination values for three inclination-group models from Detroit Seamount.
Errors are 95% confidence interval. Also shown is the predicted inclination at 81 Ma based on prior
Pacific apparent polar wander path (APNP) poles (Gordon, 1983). **B.** Paleolatitude values with
95% confidence intervals for the inclination groups. Also shown is the present-day latitude of the
Hawaiian hotspot (black line). **C. **Estimated angular dispersion (S) of the inclination groups (black
line) shown vs. the predicted values for 45-80 Ma (dark field) and 80-110 Ma (light field) from
McFadden et al., (1991). **D.** Orthographic projection of the colatitude (primary) for Detroit
seamount (star). The colatitude is distinct at the 99% confidence level (shaded) from previous 81-82
Ma poles (ellipses). Poles are derived from the following: 81 Ma (Gordon, 1983); 82 Ma (Sager
and Pringle, 1988); 33n (79.1-73.6 Ma) (Vasas et al., 1994). The sense of offset between the NRM
data and the demagnetized (primary) data is the same as that between the new paleolatitude result
and results based on prior Pacific pole positions. This is the effect expected if these previous pole
positions are contaminated by secondary magnetizations. Figure is after Tarduno and Cottrell
(1997). VGP = virtual geomagnetic pole.
