based on maps of Wood 1934, Wheeler 1961, and West 1976a this appears to be the same as Hickey Mountain presumed to fall entirely in Bridger D based on available records "Telmatherium cultridens" type is actually from Henry's Fork Hill, see Osborn 1929 |

all fossils are from a single quarry within a member | "tuffaceous mudstone, sandstone, and siliceous limestone" (Nelson 1973) or "tuffaceous mudstone and sandstone" (Nelson 1974, 1977) | close to the Utah state line and well west of the Green River Basin date of 47.9 (49.1 corrected) +/- 1.9 Ma (K-Ar on biotite) on a sample immediately above the quarry; date of 47.7 Ma reported earlier is from a site 48 km to the north | ||

said to be early Uintan | replaces assorted Sand Wash lists of West and Dawson 1975 West and Dawson report specimen counts, but these are not valid estimates in light of the later CM collections apparently from a restricted stratigraphic interval that is correlable with the lower Adobe Town Mbr. in the Washakie Basin "Hemiacodon sp." is said to be "Washakius sp." of West and Dawson, which is from Lang Springs "Viverravus sp." is probably the specimen from Lang Springs described by West and Dawson 1975 "Tillomys cf. senex": probably the specimen from Lang Springs described by West and Dawson 1975 true identity of numerous remaining brontotheres of both West and Dawson 1975 and Stucky et al. is completely unclear; "Tanyorhinus" species could be Dolichorhinus or something else, and "Manteoceras" species could be Metatelmatherium, Dolichorhinus, or Telmatherium; Mader 1989 added Metatelmatherium ultimum to the list, but this is omitted by Stucky et al.; similarly, "Sphenocoelus sp." is listed by Prothero and Schoch 1989 but ignored by both Mader and Stucky et al. |

this unit spans beds 569 to 620 of Roehler; most of this interval is reversed, but there are two normal excursions of unclear significance; it is best treated as a reversed chron immediately preceding the normal chron seen in the overlying unit Turnbull 1972 distinguished "upper" and "lower" Washakie A faunas but the upper fauna is duplicated almost entirely by the lower fauna and the two are merged by McCarroll et al.; list is still incomplete and certain older i.d.s therefore may be valid |

this unit spans beds 620 to 675 of Roehler; most of the fauna appears to be from the lower half, which is entirely in a normal polarity interval replaces list of Turnbull 1972 |
