Isopleth map of Hagerman Fossil Beds National Monument (HAFO), showing change in elevation necessary to adjust localities in Glenns Ferry Formation to HHQ datum. SS1, SS2, and SS3 indicate positions of measured sections reported by Lee et al. (1995); A, B, C, D, E, F, and H show positions of measured sections (by Bjork, 1970) used here. Shaded area represents faulted area where no estimates are made as to elevation changes needed to adjust to HHQ datum. Isopleths dashed where placed with less certainty. Isopleths as drawn continue under thin deposits of colluvium, Yahoo Clay, Crowsnest Gravel, or small isolated pockets of Tuana Gravel, but not under much more substantial exposures of Tuana Gravel capping plateau to west of HAFO.
