/Cedarville series [informal] (CA)
[When referring to the Cedarville series of Russell (1928), please use informally. Or, see NACSN (2021, Art. 29a, 38) for suggestions on replacement terms. The practice of employing "Series" for lithostratigraphic or lithodemic nomenclature is now regarded as improper (ACSN, 1961, 1970; NACSN, 1983, 2005, 2021). The term "Series" is applied formally only to chronostratigraphic units.]
Tertiary (late Oligocene to Miocene)
Not stated. Makes up great bulk of Warner Range, west of Cedarville, CA (Russell, 1928).
Southern Oregon basin
