Pg. 3 (fig. 2), 6-7, 16 (fig. 6), 20+ (measured sections), pl. 1 (corr. chart). Red Tops Member of Notch Peak Formation. Mostly thin-bedded, light-brown weathering, bioclastic lime grainstone; contains some halite and gypsum of probable secondary origin. Thickness 140 feet (42.7 m) at type section, 50 feet (15.2 m) at reference section. Is middle member of the Notch Peak Formation. Exposed in the House Range and Wah Wah Mountains; forms beds less resistant than the more massive Lava Dam Member (new) above and Hellnmaria Member (new) below. Age equivalent of parts of Chokecherry Dolomite of Deep Creek Range, Dugway Ridge Dolomite of Dugway Range, and Ajax Dolomite of Sheeprock and East Tintic Mountains. Fossils [listed]. Contains faunas of SAUKIA trilobite zone (SAUKIELLA PYRENE to SAUKIELLA SEROTINA subzone), PROCONODONTUS conodont zone (PROCONODONTUS POSTEROCOSTATUS to CAMBROOISTODUS MINUTUS subzone). Age is Late Cambrian (late Croixan; Trempeauleauan).
