Within a tile (see Section 29) to the east, this -eroding (removal in pre-historic times) calcaireite began working to any higher sections, but still large valleys are apparent on the upper slope facing N.E. grayland coarse shales and gradiate into what might be reserved to be an 'adductile' zone based on colors. Orange brown SS are cross folded. Bed 14 of Sect. 33, as probably equivalent to bed 9 of sect. 32, but might be as old as Sect 37 bed 7 - but doubtful. Beds # 8 through 13 of Section 33 probably represent greenish shales of section 32. Bed 7 might be included in this grouping also.
