• coordinate stated in text

• small collection-level geographic resolution

When: Cornell Dam Member (Valentine Formation), Barstovian (16.3 - 12.5 Ma)

• Hurlbut Ash in CD Mbr. dated at 11.6 +/- 1.1 (recalibrated from 13.6 +/- 1.3) Ma FT on glass; this date is anomalous and the recalibration was never justified
