LOC 100 (1) Spindle-burrow bed (same horizon as in Unit 10A of Sec A) is up to 4' thick locally - probably move (2) Some nodules (Coll.) at contact of massive-thumbedded sands, but not a well defined layer as at Gunn Ranch. (3) Ophiomorpha either more common in "white" sands or more obvious. (4) Massive yellow-orange sands appears thicker. (5) Bzuded beds 25'+ between 1st + 2nd white sands LOC 108 Bluffs of "bzuled beds" lying about an axis of Antihills syncline.. Not certain of relationship to "white" sands - could be above. On main bluff nearest road d cone. layer approx 25' below the capping sand contains small Ophiomorpha. This only fossil except bone fragment. BB's, however, have abundant meucsite pellets 34
