LOC. 20-A Southwest-facing bluffs southeast of locality 20, on some west-treading spur as 20, in the NW¼, sec. 9, T. 20 N., R. 27 E, Little Eagle 7½' gwdy, Corson Co. Here the Timber Lake-Trail City contact is sharp and the "abyssinus" conc. layer comes in a few feet below it. Most these concs are broken but some have fossils. They are typified by numerous juveniles, abyssinus, mendzensis, nebraskaensis, and Plinguiiformis. One or two of these found here, but exposures not good. Better exposures at Loc. 63 to west. Also present are Gervilliz and Nicolleti concs. Total Trail City not exposed but can be blocked in on its conc layers. Elk Butte exposures are not good on west and south. Little possibility of section. Use Cobbzus. 16
