| "Huerfano facies" | Lostcabinian "Most of Wortman's collection of 1897 came from here and probably from unit 13 of measured section; unit 13 has consistently produced good specimens and matches the description of the best bone-bearing layer given by Wortman to Osborn. Granger and Olsen also made good collections here." | |||

| "35 m below the contact of the Wasatch Formation with the Scheggs Bed of the Tipton Shale Member of the Green River Formation" and now assigned to the main body of the Wasatch Formation per Smith and Holroyd 2003. | UCMP,USNM | this is almost due N of Big Piney and west of the New Fork- Big Sandy area; Gazin's La Barge localities are S of Big Piney, except some about 12 mi due N on Muddy Creek that are referred to as "Red Buttes" or "Muddy Creek" elsewhere in the literature This locality previously referred to Knight Mbr. or LaBarge Mbr. but these rocks placed in main body of Wasatch Fm. by Roehler 1992. | ||
