Notes on Cloverly along Middle Fork Powder River East of preceding sections. Some relationship holds at Rusty-Cloverly contact; i.e. in local low areas on top of the "sparkly" SS, claysstone beds come into the section between contact & the SS. Laterally the Rusty beds rest directly on the SS, or very close to it, and there is a log conglomerate layer of polished pebbles. Because of apparent lack of continuous key layers the relation of Rusty bed detailed stratig. to the "highs" on the sparkly SS were not determined. At Loc. reached by taking first right from end of pavement on Bernum road, going about miles and walking W & NW along top of "sparkly SS" ridge into sec. 33 T 43 N R 83 W - Rusty beds chiefly on or very close to "sparkly" with amazing local accumulations of polished pebbles - either loose in silty cstm beneath contact or incorp in top layer of Fe impreg. SS at contact. Locally a typical Rusty bed ironstone sits directly on contact - though elsewhere the first of these Fe-stones 70
