underlies Whistler Squat
said by Prothero 1996b to be Bridgerian; Figure 2 of Wilson indicates that it is roughly at the level of the Alamo Creek Basalt because both are above the "basal Tertiary conglomerate" and below the "variegated bentonites"; the ACB is dated at 46 Ma (KA), and a tuff just below it at 46.0 +/- 1.0 Ma (KA) and 46.29 +/- 0.05 Ma (AA); latter date seems best
the following taxa are from Junction, exact locality unknown: Scenopagus priscus Centetodon pulcher ? Entomolestes sp. Nyctitherium velox cf. Pantolestes sp.

Ourayia uintensis5 Osborn 1895 tarsier includes "Homacodon cf. vagans" of West 1982 according to Stucky 1998, but Stucky means to refer to specimen of "Helohyus sp." figured and described by West and identity of "H. cf. vagans" specimen is unclear: Walsh 2000
