Field Trip To Ione Basin--October 25-27, 2002

Western Foothills Of The Sierra Nevada

Amador County, California

Students and their professors from a Community College and a university collect fossil plants at famous Lygodium Gulch, one the truly great fossil leaf-bearing localities in the Ione Basin, western foothills of the Sierra Nevada, Amador County, California. The student-professor crews had volunteered to help paleobotanist Howard Schorn, retired Collections Manager Of Fossil Plants at the Univsersity California Museum Of Paleontology in Berkeley, collect plant fossils from the Middle Eocene Ione Formation. The many boxes of paleobotanical specimens recovered here would be used in a project, underwritten by the National Science Foundation, to study the numerous Eocene fossil floras of the Sierra Nevada region, to try to determine the ancestral paleoelevations and paleoclimate of the Eocene Sierra Nevada.

Please note: All fossil localities in the Ione Formation of Amador County, California, presently occur on private property; explicit permission from the land owners must be secured before collecting fossils there.
