Figure 9. Large-scale view of South Mesa paleomagnetic section (labeled SM on Figure 3 and Figure 4). Stratigraphic levels of samples collected for paleomagnetic analyses are shown in meters above or below base of Ojo Alamo Sandstone. Plot is expanded-scale rendition of upper part of Hunter Wash/Alamo Wash section of Lindsay et al. (1981) of Figure 8; top of chron C29n was not determined. (Magnetochron labels are now known to be incorrect as discussed in section of this paper labeled "Identification of Kirtland Formation-Ojo Alamo Sandstone Magnetochrons.")
