Stratigraphy
Formation: | Mount Hope | ||||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From what Scott (pers comm., 1911) referred to as the "Mount Hope Fm", which at this locality overlies the Gatun Fm. THICKNESS: Unknown stratigraphic thickness. AGE: Pleistocene, presumably (given geographic position) the Early Pleistocene. STRATIGRAPHIC POSITION: From the oyster bearing strata lying unconformably upon the Gatun Fm. |
