• 968 m above 1264. The Permian part of the Lee Canyon section is 1,616 m thick. As first recognized by Barosh (1968), it has three lithologic units: a lower limestone sequence (238 m thick), a central sandstone sequence with some thin limestone beds (1,037 m thick), and an upper sandstone-limestone sequence (341 m thick). The middle sandstone sequence lies entirely within the Zone of Pseudoschwagerina. The limestone at the top of the predominately sandstone unit (at this locality) was correlated by Baroh (1986) with the "Rib Hill" Sandstone of the Egan Range, White Pine County, Nevada. The loc. 1268 limestone and overlying thin-bedded sandstones were considered by Barosh (1986) to be equivalent to the Arcturus Formation of the Egan Range.
