Sections to be measured and specific data needed at each. From Lance Creek area E and N #1 - Locality 101: First appreciable section of Fox Hills possible, From base massive or, slightly below, to Lance. KEY HORIZONS - zone of jacketed cones in lower massive is 15' or more thick. A zone #2 probably have too. The phosphatic module horizon not in here, tho phosphatic nodules scattered in upper part massive. Massive proper gives way to tabular X-12m unit 4 to 10'; this can probably be traced into Locality 100 - we carried it 1 mile E of N. prong Crazy Woman Cr. and it began to thin and become greenish. Large irreg. oval rb. weth cones some with Venicells lie approx at change from massive to tab, X-12m except to east where tabo massive extends above this layer. Scattered Venicells, the reddbrown cones, isolated "turds" typify the massive in upper 5-10' whereas none of these present in tabular which is typified by X-lamination of debris streaks, clay blebs and subangular fragments, flow structure, thin shaly layers - none of which occur in massive contact should be walked out to Loc. 100 to see whether the tabular goes laterally into the massive, or not. Scattering of the "turds" and phosphatic steinkerns in upper 5'+ of massive suggests that the phosphatic layer at 100 and localities to E + N may have been formed by the winnowing of upper massive to form lay concentrate. The "bended beds" here are more steudy than to E along 85 and consist of tab. X-12m ss, thin bedded ss + minor sh, and numerous slubby conc. layers. The latter show a fine 44
