Homer limestone member of Wayan formation. Referred 4 times (and showed its distribution on geologic map) to Homer limestone member of Wayan formation. Lower Cretaceous(?) southeastern Idaho, but did not define it. In Jour. Geol., v. 29, 1921, p. 458, 459, Mansfield casually referred twice to same unit, and also mapped it.

Pg. 107. Homer limestone member of Wayan formation. Occurs in northeastern part of Cranes Flat quadrangle and extends into adjacent regions north and east. Its stratigraphic position is not known definitely. Ordinarily the surface underlain by it is strewn with white pieces of rock, which by their arrangement on the slopes suggest the attitude of the beds. Locally, as on slope northeast of Sugarloaf Mountain, the limestone forms massive ledges. At this place some of upper beds are dull gray, coarsely crystalline, and crowded with poorly preserved fossils [pelecypods, gastropods identified by T.W. Stanton, USGS; listed, see p. 107]. [Age is considered Early(?) Cretaceous.]
[Named from exposures in valley of Homer Creek, Cranes Flat quadrangle, Bingham Co., southeastern ID.]
