Type locality not stated. Well exposed on Axes Creek in Beaverhead Co., MT.
[GNC remark (November 23, 2007): "Axes Creek phase" considered informal. The practice of employing "Phase" for lithostratigraphic or lithodemic nomenclature is now regarded as improper. Term "Phase" is applied formally only to diachronic units (NACSN, 1983, 2005, 2021).
"Cherry Creek series" considered informal. The practice of employing "Series" for lithostratigraphic or lithodemic nomenclature is now regarded as improper. Term "Series" is applied formally only to chronostratigraphic units (ACSN, 1961, 1970; NACSN, 1983, 2005, 2021).]
