Henry Redbird owns most of 12nd E Thunder Butte village on Monzon. Trip with Doug Black, Dr Tullis, Earl Cox and Joe Collick Bullhead - Colgate exposed in E bluffs above Red Coat Creek south of Pehlesuzke Butte. Here the Bullhead is less sandy and more bentonitic; it lacks fossils. Chiefly a silt or bentonitic silt, banding less evident. The Colgate has bands of shale and the typical huge brown concretions; sand friable, crossbedding evident, is less clayey than on Ground at Hump Creek. Plant frags are abundant throughout. This is just E. of Freeman ranch and probably on it. Along road to ranch (west through gate) flat at base banded beds has thin zone - 10'± of silty, buff shale with OB concs some containing the Timber Lake fauna. Apparently just this thin zone all that's left of the Timber Lake - beneath it featureless shale not like Trail City in type even. At "mud butte" NW of Freemans (see mosaic) oyster bed high in colgate is cap rock. Blacks' White Thunder section; sampled two zones highly calcareous foraminiferal shale above and below his "double bentonite" zone. Also microfossil sample of highest baculites in this section (these may be highest in his Pierre but he is not positive). Should get generalized section of this locality from him. 5
