Summary:
Rocks originally defined by Ferguson and others (1951) now recognized by Nichols (1972) and N.J. Silberling (oral commun., 1973) as identical to middle member of the Augusta Mountain Formation (Muller and others, 1951) for exposures in Augusta Mountain. Accordingly name Panther Canyon Formation is considered obsolete, its rocks being reassigned to Augusta Mountain Formation.

Summary:
Muller and others (1951) originally divided Augusta Formation into 3 informal members but did not realize their middle member was also the Panther Canyon Formation. Panther Canyon reduced in rank to Panther Canyon Member of Augusta Mountain Formation (citing Nichols, 1974). Rocks of the Panther Canyon have been mapped as part of Prida, Favret, Natchez Pass, and Augusta Mountain Formations (Ferguson and others, 1951a, 1951b, 1952; Muller and others, 1951; Silberling and Roberts, 1962; Silberling and Wallace, 1969). [See also, Johnson (1977) where name abandoned.] In Augusta Mountain, unconformably overlies Home Station Member (new) of August Mountain Formation; in Humboldt and East Ranges, overlies upper member of the Prida Formation; at China Mountain, overlies the Fossil Hill Formation and locally overlies Koipato Group. Underlies Smelser Pass Member (new) of Augusta Mountain Formation. Age is Middle Triassic, based on stratigraphic position.
