Figure 6. Photograph of Barrel Spring locality (looking north) of Lindsay et al. (1981); location is shown on Figure 3 and Figure 4. Magnetochron labels for Ojo Alamo Sandstone are corrected as discussed in the "Identification of Kirtland Formation-Ojo Alamo Sandstone Magnetochrons" section of this report. Lindsay et al.'s (1981) paleomagnetic data plot at this locality is on Figure 5. Numbered arrow heads are distances above base of Ojo Alamo Sandstone in meters; sample levels are approximate. Arrow heads pointing left indicate reversed polarity, arrow heads pointing right indicate normal polarity. Sample levels are estimated from Figure 5, but exact original sample localities are not known.
