Two views looking northeast to roughly the same southern Chalk Bluff ridge section, western foothills of California's Sierra Nevada. Youngest acummulations of the middle Eocene aurifeous gravels comprise the slopes. Fossil leaves occur in lenticular clay lenses about halfway up the incline. Top photo snapped in latest 20th Century; bottom photograph taken between 1933 and 1938--from the volume A Middle Eocene Flora From The Central Sierra Nevada, by H. D. MacGinitie, Carnegie Institute of Washington Publication 534, 1941.
