Taxonomic list comments: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.
