variety of burrows, trails and other bedding structures that should be recorded in detail. For collecting suggest using casting medium in field to get record. Among others are normal Itzlymautes, strictly horizontal Itzlymautes, double castings on bedding surfaces, vertical pipes, vertical "funnels" shaped like -- "Colgate" also has bedding structures on slabby layers. Also look at shales between massive white sands. Some very local variation of clayey beds assoc. with the Corbicula lens - is it primary? Need to match "colgate" at 101 with that at 100. Luce: Should carry the section high enough to be well into it, as contact will be problem. REMARKS. Section cannot be measured directly as dip too steep - whole will have to be calculated from crop measurements. Several sections of massive and banded may have to be made betw. N. prong Crazy Woman and about 3/4 mile E. Fossils in massive chiefly Vanella - lower conc. zone seems betwen + no Bryozoa cones seen. #2 Locality 100; Section in windmill gulley & adjacent parts. Probably can use the 1938 measurements but they should be checked. Massive unit: Three conc. zones not as sharply defined as at Wasserburger Ranch, but does have zone jacketed cones at base though these sparingly fossiliferous. The phosphatic nodule layer conspicuous at top though not associated with large concretions as in Aukt Hills + north. 45
