Northeastern Carlile Quad. with Max Bergendahl and Bob Davis. Fall River - here consistently 3 sandstone units with dk gray shale interval between #1 and #2, ascending. #1 is thin bedded chiefly, rarely becomes massive. Distance above contact with Fuson-Lzkote series. Shale between it and #2 dk gray with selenite. No obvious thin SS beds + Max didn't mention any. #2 is the most prominent, most consistently massive tho it may have thin-bedded parts. Max pointed out calcaceous, round, concretions in it, formed by CaCO3 impreg. in spherical form. Also some thin lenses CaCO3 sandstone in base,-convex downward where I saw them. Max has found no cgl in the Fall River, consistently # fine-grained, commonly micaceous. #3 sand separated by only a few feet sandy shale from #2, is more commonly thin bedded but locally it too gets massive - may locally coalesce with #2. Top seems consistently platy. Overlain by good Skull Creek Sh.
